SBV: SMT Based Verification

Express properties about Haskell programs and automatically prove them using SMT solvers.

>>> prove $ \x -> x `shiftL` 2 .== 4 * (x :: SWord8)
Q.E.D.

>>> prove $ \x -> x `shiftL` 2 .== 2 * (x :: SWord8)
Falsifiable. Counter-example:
  s0 = 32 :: Word8

The function prove has the following type:

    prove :: Provable a => a -> IO ThmResult

The class Provable comes with instances for n-ary predicates, for arbitrary n. The predicates are just regular Haskell functions over symbolic types listed below. Functions for checking satisfiability (sat and allSat) are also provided.

The sbv library introduces the following symbolic types:

• SBool: Symbolic Booleans (bits).
• SWord8, SWord16, SWord32, SWord64: Symbolic Words (unsigned).
• SInt8, SInt16, SInt32, SInt64: Symbolic Ints (signed).
• 'SWord n': Generalized symbolic words of arbitrary bit-size.
• 'SInt n': Generalized symbolic ints of arbitrary bit-size.
• SInteger: Unbounded signed integers.
• SReal: Algebraic-real numbers
• SFloat: IEEE-754 single-precision floating point values
• SDouble: IEEE-754 double-precision floating point values
• SChar, SString, RegExp: Characters, strings and regular expressions
• SList: Symbolic lists (which can be nested)
• STuple, STuple2, STuple3, .., STuple8 : Symbolic tuples (upto 8-tuples, can be nested)
• SEither: Symbolic sums
• SMaybe: Symbolic optional values
• SSet: Symbolic sets
• SArray, SFunArray: Flat arrays of symbolic values.
• Symbolic polynomials over GF(2^n), polynomial arithmetic, and CRCs.
• Uninterpreted constants and functions over symbolic values, with user defined SMT-Lib axioms.
• Uninterpreted sorts, and proofs over such sorts, potentially with axioms.
• Model validation: SBV can validate models returned by solvers, which allows for protection against bugs in SMT solvers and SBV itself. (See the validateModel parameter.)

The user can construct ordinary Haskell programs using these types, which behave very similar to their concrete counterparts. In particular these types belong to the standard classes Num, Bits, custom versions of Eq (EqSymbolic) and Ord (OrdSymbolic), along with several other custom classes for simplifying programming with symbolic values. The framework takes full advantage of Haskell's type inference to avoid many common mistakes.

Furthermore, predicates (i.e., functions that return SBool) built out of these types can also be:

• proven correct via an external SMT solver (the prove function)
• checked for satisfiability (the sat, allSat functions)
• used in synthesis (the sat function with existentials)
• quick-checked

If a predicate is not valid, prove will return a counterexample: An assignment to inputs such that the predicate fails. The sat function will return a satisfying assignment, if there is one. The allSat function returns all satisfying assignments.

The sbv library uses third-party SMT solvers via the standard SMT-Lib interface: http://smtlib.cs.uiowa.edu/

The SBV library is designed to work with any SMT-Lib compliant SMT-solver. Currently, we support the following SMT-Solvers out-of-the box:

• ABC from University of Berkeley: http://www.eecs.berkeley.edu/~alanmi/abc/
• CVC4 from Stanford: http://cvc4.cs.stanford.edu/web/
• Boolector from Johannes Kepler University: http://fmv.jku.at/boolector/
• MathSAT from Fondazione Bruno Kessler and DISI-University of Trento: http://mathsat.fbk.eu/
• Yices from SRI: http://yices.csl.sri.com/
• Z3 from Microsoft: http://github.com/Z3Prover/z3/wiki

SBV requires recent versions of these solvers; please see the file SMTSolverVersions.md in the source distribution for specifics.

SBV also allows calling these solvers in parallel, either getting results from multiple solvers or returning the fastest one. (See proveWithAll, proveWithAny, etc.)

Support for other compliant solvers can be added relatively easily, please get in touch if there is a solver you'd like to see included.

Documentation

The SBV library is really two things:

• A framework for writing symbolic programs in Haskell, i.e., programs operating on symbolic values along with the usual concrete counterparts.
• A framework for proving properties of such programs using SMT solvers.

The programming goal of SBV is to provide a seamless experience, i.e., let people program in the usual Haskell style without distractions of symbolic coding. While Haskell helps in some aspects (the Num and Bits classes simplify coding), it makes life harder in others. For instance, if-then-else only takes Bool as a test in Haskell, and comparisons (> etc.) only return Bools. Clearly we would like these values to be symbolic (i.e., SBool), thus stopping us from using some native Haskell constructs. When symbolic versions of operators are needed, they are typically obtained by prepending a dot, for instance == becomes .==. Care has been taken to make the transition painless. In particular, any Haskell program you build out of symbolic components is fully concretely executable within Haskell, without the need for any custom interpreters. (They are truly Haskell programs, not AST's built out of pieces of syntax.) This provides for an integrated feel of the system, one of the original design goals for SBV.

Incremental query mode: SBV provides a wide variety of ways to utilize SMT-solvers, without requiring the user to deal with the solvers themselves. While this mode is convenient, advanced users might need access to the underlying solver at a lower level. For such use cases, SBV allows users to have an interactive session: The user can issue commands to the solver, inspect the values/results, and formulate new constraints. This advanced feature is available through the Data.SBV.Control module, where most SMTLib features are made available via a typed-API.

Unbounded integers

The SBV library supports unbounded signed integers with the type SInteger, which are not subject to overflow/underflow as it is the case with the bounded types, such as SWord8, SInt16, etc. However, some bit-vector based operations are not supported for the SInteger type while in the verification mode. That is, you can use these operations on SInteger values during normal programming/simulation. but the SMT translation will not support these operations since there corresponding operations are not supported in SMT-Lib. Note that this should rarely be a problem in practice, as these operations are mostly meaningful on fixed-size bit-vectors. The operations that are restricted to bounded word/int sizes are:

• Rotations and shifts: rotateL, rotateR, shiftL, shiftR
• Bitwise logical ops: .&., .|., xor, complement
• Extraction and concatenation: bvExtract, #, zeroExtend, signExtend, bvDrop, and bvTake

Usual arithmetic (+, -, *, sQuotRem, sQuot, sRem, sDivMod, sDiv, sMod) and logical operations (.<, .<=, .>, .>=, .==, ./=) operations are supported for SInteger fully, both in programming and verification modes.

type SInteger = SBV Integer

Infinite precision signed symbolic value

Floating point numbers

Floating point numbers are defined by the IEEE-754 standard; and correspond to Haskell's Float and Double types. For SMT support with floating-point numbers, see the paper by Rummer and Wahl: http://www.philipp.ruemmer.org/publications/smt-fpa.pdf.

type SFloat = SBV Float

IEEE-754 single-precision floating point numbers

type SDouble = SBV Double

IEEE-754 double-precision floating point numbers

Algebraic reals

Algebraic reals are roots of single-variable polynomials with rational coefficients. (See http://en.wikipedia.org/wiki/Algebraic_number.) Note that algebraic reals are infinite precision numbers, but they do not cover all real numbers. (In particular, they cannot represent transcendentals.) Some irrational numbers are algebraic (such as sqrt 2), while others are not (such as pi and e).

SBV can deal with real numbers just fine, since the theory of reals is decidable. (See http://smtlib.cs.uiowa.edu/theories-Reals.shtml.) In addition, by leveraging backend solver capabilities, SBV can also represent and solve non-linear equations involving real-variables. (For instance, the Z3 SMT solver, supports polynomial constraints on reals starting with v4.0.)

type SReal = SBV AlgReal

Infinite precision symbolic algebraic real value

Characters, Strings and Regular Expressions

Support for characters, strings, and regular expressions (intial version contributed by Joel Burget) adds support for QF_S logic, described here: http://smtlib.cs.uiowa.edu/theories-UnicodeStrings.shtml and here: http://rise4fun.com/z3/tutorialcontent/sequences. Note that this logic is still not part of official SMTLib (as of March 2018), so it should be considered experimental.

See Data.SBV.Char, Data.SBV.String, Data.SBV.RegExp for related functions.

type SChar = SBV Char

A symbolic character. Note that, as far as SBV's symbolic strings are concerned, a character is currently an 8-bit unsigned value, corresponding to the ISO-8859-1 (Latin-1) character set: http://en.wikipedia.org/wiki/ISO/IEC_8859-1. A Haskell Char, on the other hand, is based on unicode. Therefore, there isn't a 1-1 correspondence between a Haskell character and an SBV character for the time being. This limitation is due to the SMT-solvers only supporting this particular subset. However, there is a pending proposal to add support for unicode, and SBV will track these changes to have full unicode support as solvers become available. For details, see: http://smtlib.cs.uiowa.edu/theories-UnicodeStrings.shtml

type SString = SBV String

A symbolic string. Note that a symbolic string is not a list of symbolic characters, that is, it is not the case that SString = [SChar], unlike what one might expect following Haskell strings. An SString is a symbolic value of its own, of possibly arbitrary but finite length, and internally processed as one unit as opposed to a fixed-length list of characters.

Symbolic lists

Support for symbolic lists (intial version contributed by Joel Burget) adds support for sequence support, described here: http://rise4fun.com/z3/tutorialcontent/sequences. Note that this logic is still not part of official SMTLib (as of March 2018), so it should be considered experimental.

See Data.SBV.List for related functions.

type SList a = SBV [a]

A symbolic list of items. Note that a symbolic list is not a list of symbolic items, that is, it is not the case that SList a = [a], unlike what one might expect following haskell lists/sequences. An SList is a symbolic value of its own, of possibly arbitrary but finite length, and internally processed as one unit as opposed to a fixed-length list of items. Note that lists can be nested, i.e., we do allow lists of lists of ... items.

Tuples

Tuples can be used as symbolic values. This is useful in combination with lists, for example SBV [(Integer, String)] is a valid type. These types can be arbitrarily nested, eg SBV [(Integer, [(Char, (Integer, String))])]. Instances of upto 8-tuples are provided.

Arrays of symbolic values

class SymArray array where

Flat arrays of symbolic values An array a b is an array indexed by the type SBV a, with elements of type SBV b.

If a default value is supplied, then all the array elements will be initialized to this value. Otherwise, they will be left unspecified, i.e., a read from an unwritten location will produce an uninterpreted constant.

While it's certainly possible for user to create instances of SymArray, the SArray and SFunArray instances already provided should cover most use cases in practice. Note that there are a few differences between these two models in terms of use models:

• SArray produces SMTLib arrays, and requires a solver that understands the array theory. SFunArray is internally handled, and thus can be used with any solver. (Note that all solvers except abc support arrays, so this isn't a big decision factor.)
• For both arrays, if a default value is supplied, then reading from uninitialized cell will return that value. If the default is not given, then reading from uninitialized cells is still OK for both arrays, and will produce an uninterpreted constant in both cases.
• Only SArray supports checking equality of arrays. (That is, checking if an entire array is equivalent to another.) SFunArrays cannot be checked for equality. In general, checking wholesale equality of arrays is a difficult decision problem and should be avoided if possible.
• Only SFunArray supports compilation to C. Programs using SArray will not be accepted by the C-code generator.
• You cannot use quickcheck on programs that contain these arrays. (Neither SArray nor SFunArray.)
• With SArray, SBV transfers all array-processing to the SMT-solver. So, it can generate programs more quickly, but they might end up being too hard for the solver to handle. With SFunArray, SBV only generates code for individual elements and the array itself never shows up in the resulting SMTLib program. This puts more onus on the SBV side and might have some performance impacts, but it might generate problems that are easier for the SMT solvers to handle.

As a rule of thumb, try SArray first. These should generate compact code. However, if the backend solver has hard time solving the generated problems, switch to SFunArray. If you still have issues, please report so we can see what the problem might be!

Symbolic Equality and Comparisons

class EqSymbolic a where

Symbolic Equality. Note that we can't use Haskell's Eq class since Haskell insists on returning Bool Comparing symbolic values will necessarily return a symbolic value.

Minimal complete definition

(.==)

Methods

(.==) :: a -> a -> SBool infix 4

Symbolic equality.

(./=) :: a -> a -> SBool infix 4

Symbolic inequality.

(.===) :: a -> a -> SBool infix 4

Strong equality. On floats ('SFloat'/'SDouble'), strong equality is object equality; that is NaN == NaN holds, but +0 == -0 doesn't. On other types, (.===) is simply (.==). Note that (.==) is the right notion of equality for floats per IEEE754 specs, since by definition +0 == -0 and NaN equals no other value including itself. But occasionally we want to be stronger and state NaN equals NaN and +0 and -0 are different from each other. In a context where your type is concrete, simply use fpIsEqualObject. But in a polymorphic context, use the strong equality instead.

NB. If you do not care about or work with floats, simply use (.==) and (./=).

(./==) :: a -> a -> SBool infix 4

Negation of strong equality. Equaivalent to negation of (.===) on all types.

distinct :: [a] -> SBool

Returns (symbolic) sTrue if all the elements of the given list are different.

allEqual :: [a] -> SBool

Returns (symbolic) sTrue if all the elements of the given list are the same.

sElem :: a -> [a] -> SBool

Symbolic membership test.

Symbolic Comparisons. Similar to Eq, we cannot implement Haskell's Ord class since there is no way to return an Ordering value from a symbolic comparison. Furthermore, OrdSymbolic requires Mergeable to implement if-then-else, for the benefit of implementing symbolic versions of max and min functions.

Conditionals: Mergeable values

class Mergeable a where

Symbolic conditionals are modeled by the Mergeable class, describing how to merge the results of an if-then-else call with a symbolic test. SBV provides all basic types as instances of this class, so users only need to declare instances for custom data-types of their programs as needed.

A Mergeable instance may be automatically derived for a custom data-type with a single constructor where the type of each field is an instance of Mergeable, such as a record of symbolic values. Users only need to add Generic and Mergeable to the deriving clause for the data-type. See Status for an example and an illustration of what the instance would look like if written by hand.

The function select is a total-indexing function out of a list of choices with a default value, simulating array/list indexing. It's an n-way generalization of the ite function.

Minimal complete definition: None, if the type is instance of Generic. Otherwise symbolicMerge. Note that most types subject to merging are likely to be trivial instances of Generic.

Minimal complete definition

Nothing

Methods

symbolicMerge :: Bool -> SBool -> a -> a -> a

Merge two values based on the condition. The first argument states whether we force the then-and-else branches before the merging, at the word level. This is an efficiency concern; one that we'd rather not make but unfortunately necessary for getting symbolic simulation working efficiently.

select :: (Ord b, SymVal b, Num b) => [a] -> a -> SBV b -> a

Total indexing operation. select xs default index is intuitively the same as xs !! index, except it evaluates to default if index underflows/overflows.

symbolicMerge :: (Generic a, GMergeable (Rep a)) => Bool -> SBool -> a -> a -> a

Merge two values based on the condition. The first argument states whether we force the then-and-else branches before the merging, at the word level. This is an efficiency concern; one that we'd rather not make but unfortunately necessary for getting symbolic simulation working efficiently.

ite :: Mergeable a => SBool -> a -> a -> a

If-then-else. This is by definition symbolicMerge with both branches forced. This is typically the desired behavior, but also see iteLazy should you need more laziness.

iteLazy :: Mergeable a => SBool -> a -> a -> a

A Lazy version of ite, which does not force its arguments. This might cause issues for symbolic simulation with large thunks around, so use with care.

Symbolic integral numbers

class (SymVal a, Num a, Bits a, Integral a) => SIntegral a

Symbolic Numbers. This is a simple class that simply incorporates all number like base types together, simplifying writing polymorphic type-signatures that work for all symbolic numbers, such as SWord8, SInt8 etc. For instance, we can write a generic list-minimum function as follows:

   mm :: SIntegral a => [SBV a] -> SBV a
   mm = foldr1 (a b -> ite (a .<= b) a b)

It is similar to the standard Integral class, except ranging over symbolic instances.

Division and Modulus

class SDivisible a where

The SDivisible class captures the essence of division. Unfortunately we cannot use Haskell's Integral class since the Real and Enum superclasses are not implementable for symbolic bit-vectors. However, quotRem and divMod both make perfect sense, and the SDivisible class captures this operation. One issue is how division by 0 behaves. The verification technology requires total functions, and there are several design choices here. We follow Isabelle/HOL approach of assigning the value 0 for division by 0. Therefore, we impose the following pair of laws:

     x sQuotRem 0 = (0, x)
     x sDivMod  0 = (0, x)

Note that our instances implement this law even when x is 0 itself.

NB. quot truncates toward zero, while div truncates toward negative infinity.

C code generation of division operations

In the case of division or modulo of a minimal signed value (e.g. -128 for SInt8) by -1, SMTLIB and Haskell agree on what the result should be. Unfortunately the result in C code depends on CPU architecture and compiler settings, as this is undefined behaviour in C. **SBV does not guarantee** what will happen in generated C code in this corner case.

Bit-vector operations

Conversions

sFromIntegral :: forall a b. (Integral a, HasKind a, Num a, SymVal a, HasKind b, Num b, SymVal b) => SBV a -> SBV b

Conversion between integral-symbolic values, akin to Haskell's fromIntegral

Shifts and rotates

Symbolic words (both signed and unsigned) are an instance of Haskell's Bits class, so regular bitwise operations are automatically available for them. Shifts and rotates, however, require specialized type-signatures since Haskell insists on an Int second argument for them.

sShiftLeft :: (SIntegral a, SIntegral b) => SBV a -> SBV b -> SBV a

Generalization of shiftL, when the shift-amount is symbolic. Since Haskell's shiftL only takes an Int as the shift amount, it cannot be used when we have a symbolic amount to shift with.

sShiftRight :: (SIntegral a, SIntegral b) => SBV a -> SBV b -> SBV a

Generalization of shiftR, when the shift-amount is symbolic. Since Haskell's shiftR only takes an Int as the shift amount, it cannot be used when we have a symbolic amount to shift with.

NB. If the shiftee is signed, then this is an arithmetic shift; otherwise it's logical, following the usual Haskell convention. See sSignedShiftArithRight for a variant that explicitly uses the msb as the sign bit, even for unsigned underlying types.

sRotateLeft :: (SIntegral a, SIntegral b) => SBV a -> SBV b -> SBV a

Generalization of rotateL, when the shift-amount is symbolic. Since Haskell's rotateL only takes an Int as the shift amount, it cannot be used when we have a symbolic amount to shift with. The first argument should be a bounded quantity.

sBarrelRotateLeft :: (SFiniteBits a, SFiniteBits b) => SBV a -> SBV b -> SBV a

An implementation of rotate-left, using a barrel shifter like design. Only works when both arguments are finite bitvectors, and furthermore when the second argument is unsigned. The first condition is enforced by the type, but the second is dynamically checked. We provide this implementation as an alternative to sRotateLeft since SMTLib logic does not support variable argument rotates (as opposed to shifts), and thus this implementation can produce better code for verification compared to sRotateLeft.

>>> prove $ \x y -> (x `sBarrelRotateLeft`  y) `sBarrelRotateRight` (y :: SWord32) .== (x :: SWord64)
Q.E.D.

sRotateRight :: (SIntegral a, SIntegral b) => SBV a -> SBV b -> SBV a

Generalization of rotateR, when the shift-amount is symbolic. Since Haskell's rotateR only takes an Int as the shift amount, it cannot be used when we have a symbolic amount to shift with. The first argument should be a bounded quantity.

sBarrelRotateRight :: (SFiniteBits a, SFiniteBits b) => SBV a -> SBV b -> SBV a

An implementation of rotate-right, using a barrel shifter like design. See comments for sBarrelRotateLeft for details.

>>> prove $ \x y -> (x `sBarrelRotateRight` y) `sBarrelRotateLeft`  (y :: SWord32) .== (x :: SWord64)
Q.E.D.

sSignedShiftArithRight :: (SFiniteBits a, SIntegral b) => SBV a -> SBV b -> SBV a

Arithmetic shift-right with a symbolic unsigned shift amount. This is equivalent to sShiftRight when the argument is signed. However, if the argument is unsigned, then it explicitly treats its msb as a sign-bit, and uses it as the bit that gets shifted in. Useful when using the underlying unsigned bit representation to implement custom signed operations. Note that there is no direct Haskell analogue of this function.

Finite bit-vector operations

class (Ord a, SymVal a, Num a, Bits a) => SFiniteBits a where

Finite bit-length symbolic values. Essentially the same as SIntegral, but further leaves out Integer. Loosely based on Haskell's FiniteBits class, but with more methods defined and structured differently to fit into the symbolic world view. Minimal complete definition: sFiniteBitSize.

Compute the remainder: x - y * n, where n is the truncated integer nearest to x/y. The rounding mode is implicitly assumed to be RoundNearestTiesToEven.

fpRoundToIntegral :: SRoundingMode -> SBV a -> SBV a

Round to the nearest integral value, using the given rounding mode.

fpMin :: SBV a -> SBV a -> SBV a

Compute the minimum of two floats, respects infinity and NaN values

fpMax :: SBV a -> SBV a -> SBV a

Compute the maximum of two floats, respects infinity and NaN values

fpIsEqualObject :: SBV a -> SBV a -> SBool

Are the two given floats exactly the same. That is, NaN will compare equal to itself, +0 will not compare equal to -0 etc. This is the object level equality, as opposed to the semantic equality. (For the latter, just use .==.)

fpIsNormal :: SBV a -> SBool

Is the floating-point number a normal value. (i.e., not denormalized.)

fpIsSubnormal :: SBV a -> SBool

Is the floating-point number a subnormal value. (Also known as denormal.)

fpIsZero :: SBV a -> SBool

Is the floating-point number 0? (Note that both +0 and -0 will satisfy this predicate.)

fpIsInfinite :: SBV a -> SBool

Is the floating-point number infinity? (Note that both +oo and -oo will satisfy this predicate.)

fpIsNaN :: SBV a -> SBool

Is the floating-point number a NaN value?

fpIsNegative :: SBV a -> SBool

Is the floating-point number negative? Note that -0 satisfies this predicate but +0 does not.

fpIsPositive :: SBV a -> SBool

Is the floating-point number positive? Note that +0 satisfies this predicate but -0 does not.

fpIsNegativeZero :: SBV a -> SBool

Is the floating point number -0?

fpIsPositiveZero :: SBV a -> SBool

Is the floating point number +0?

fpIsPoint :: SBV a -> SBool

Is the floating-point number a regular floating point, i.e., not NaN, nor +oo, nor -oo. Normals or denormals are allowed.

data RoundingMode

Rounding mode to be used for the IEEE floating-point operations. Note that Haskell's default is RoundNearestTiesToEven. If you use a different rounding mode, then the counter-examples you get may not match what you observe in Haskell.

Constructors

Round to nearest representable floating point value. If precisely at half-way, pick the even number. (In this context, even means the lowest-order bit is zero.)

RoundNearestTiesToAway

Round to nearest representable floating point value. If precisely at half-way, pick the number further away from 0. (That is, for positive values, pick the greater; for negative values, pick the smaller.)

Conversion to/from floats

class SymVal a => IEEEFloatConvertible a where

Capture convertability from/to FloatingPoint representations.

Conversions to float: toSFloat and toSDouble simply return the nearest representable float from the given type based on the rounding mode provided.

Conversions from float: fromSFloat and fromSDouble functions do the reverse conversion. However some care is needed when given values that are not representable in the integral target domain. For instance, converting an SFloat to an SInt8 is problematic. The rules are as follows:

If the input value is a finite point and when rounded in the given rounding mode to an integral value lies within the target bounds, then that result is returned. (This is the regular interpretation of rounding in IEEE754.)

Otherwise (i.e., if the integral value in the float or double domain) doesn't fit into the target type, then the result is unspecified. Note that if the input is +oo, -oo, or NaN, then the result is unspecified.

Due to the unspecified nature of conversions, SBV will never constant fold conversions from floats to integral values. That is, you will always get a symbolic value as output. (Conversions from floats to other floats will be constant folded. Conversions from integral values to floats will also be constant folded.)

Note that unspecified really means unspecified: In particular, SBV makes no guarantees about matching the behavior between what you might get in Haskell, via SMT-Lib, or the C-translation. If the input value is out-of-bounds as defined above, or is NaN or oo or -oo, then all bets are off. In particular C and SMTLib are decidedly undefine this case, though that doesn't mean they do the same thing! Same goes for Haskell, which seems to convert via Int64, but we do not model that behavior in SBV as it doesn't seem to be intentional nor well documented.

You can check for NaN, oo and -oo, using the predicates fpIsNaN, fpIsInfinite, and fpIsPositive, fpIsNegative predicates, respectively; and do the proper conversion based on your needs. (0 is a good choice, as are min/max bounds of the target type.)

Currently, SBV provides no predicates to check if a value would lie within range for a particular conversion task, as this depends on the rounding mode and the types involved and can be rather tricky to determine. (See http://github.com/LeventErkok/sbv/issues/456 for a discussion of the issues involved.) In a future release, we hope to be able to provide underflow and overflow predicates for these conversions as well.

Methods

fromSFloat :: SRoundingMode -> SFloat -> SBV a

Convert from an IEEE74 single precision float.

toSFloat :: SRoundingMode -> SBV a -> SFloat

Convert to an IEEE-754 Single-precision float.

105509888 % 1

Note how the numerator is different, it is off by 3. This is hardly surprising, since floats become sparser as the magnitude increases to be able to cover all the integer values representable.

Just like in the SFloat case, once we reach 64-bits, we no longer can exactly represent the integer value for all possible values:

Bit-pattern conversions

sFloatAsSWord32 :: SFloat -> SWord32

Convert an SFloat to an SWord32, preserving the bit-correspondence. Note that since the representation for NaNs are not unique, this function will return a symbolic value when given a concrete NaN.

Implementation note: Since there's no corresponding function in SMTLib for conversion to bit-representation due to partiality, we use a translation trick by allocating a new word variable, converting it to float, and requiring it to be equivalent to the input. In code-generation mode, we simply map it to a simple conversion.

sWord32AsSFloat :: SWord32 -> SFloat

Reinterpret the bits in a 32-bit word as a single-precision floating point number

sDoubleAsSWord64 :: SDouble -> SWord64

Convert an SDouble to an SWord64, preserving the bit-correspondence. Note that since the representation for NaNs are not unique, this function will return a symbolic value when given a concrete NaN.

See the implementation note for sFloatAsSWord32, as it applies here as well.

sWord64AsSDouble :: SWord64 -> SDouble

Reinterpret the bits in a 32-bit word as a single-precision floating point number

blastSFloat :: SFloat -> (SBool, [SBool], [SBool])

Extract the sign/exponent/mantissa of a single-precision float. The output will have 8 bits in the second argument for exponent, and 23 in the third for the mantissa.

blastSDouble :: SDouble -> (SBool, [SBool], [SBool])

Extract the sign/exponent/mantissa of a single-precision float. The output will have 11 bits in the second argument for exponent, and 52 in the third for the mantissa.

Enumerations

If the uninterpreted sort definition takes the form of an enumeration (i.e., a simple data type with all nullary constructors), then SBV will actually translate that as just such a data-type to SMT-Lib, and will use the constructors as the inhabitants of the said sort. A simple example is:

    data X = A | B | C
    mkSymbolicEnumeration ''X

Note the magic incantation mkSymbolicEnumeration ''X. For this to work, you need to have the following options turned on:

  LANGUAGE TemplateHaskell
  LANGUAGE StandaloneDeriving
  LANGUAGE DeriveDataTypeable
  LANGUAGE DeriveAnyClass

Now, the user can define

    type SX = SBV X

and treat SX as a regular symbolic type ranging over the values A, B, and C. Such values can be compared for equality, and with the usual other comparison operators, such as .==, ./=, .>, .>=, <, and <=.

Note that in this latter case the type is no longer uninterpreted, but is properly represented as a simple enumeration of the said elements. A simple query would look like:

     allSat $ x -> x .== (x :: SX)

which would list all three elements of this domain as satisfying solutions.

     Solution #1:
       s0 = A :: X
     Solution #2:
       s0 = B :: X
     Solution #3:
       s0 = C :: X
     Found 3 different solutions.

Note that the result is properly typed as X elements; these are not mere strings. So, in a getModelAssignment scenario, the user can recover actual elements of the domain and program further with those values as usual.

See Documentation.SBV.Examples.Misc.Enumerate for an extended example on how to use symbolic enumerations.

mkSymbolicEnumeration :: Name -> Q [Dec]

Make an enumeration a symbolic type.

Uninterpreted sorts, constants, and functions

Users can introduce new uninterpreted sorts simply by defining a data-type in Haskell and registering it as such. The following example demonstrates:

    data B = B () deriving (Eq, Ord, Show, Read, Data, SymVal, HasKind, SatModel)
 

(Note that you'll also need to use the language pragmas DeriveDataTypeable, DeriveAnyClass, and import Data.Generics for the above to work.)

This is all it takes to introduce B as an uninterpreted sort in SBV, which makes the type SBV B automagically become available as the type of symbolic values that ranges over B values. Note that the () argument is important to distinguish it from enumerations, which will be translated to proper SMT data-types.

Uninterpreted functions over both uninterpreted and regular sorts can be declared using the facilities introduced by the Uninterpreted class.

class Uninterpreted a where

Uninterpreted constants and functions. An uninterpreted constant is a value that is indexed by its name. The only property the prover assumes about these values are that they are equivalent to themselves; i.e., (for functions) they return the same results when applied to same arguments. We support uninterpreted-functions as a general means of black-box'ing operations that are irrelevant for the purposes of the proof; i.e., when the proofs can be performed without any knowledge about the function itself.

Minimal complete definition: sbvUninterpret. However, most instances in practice are already provided by SBV, so end-users should not need to define their own instances.

Properties, proofs, and satisfiability

The SBV library provides a "push-button" verification system via automated SMT solving. The design goal is to let SMT solvers be used without any knowledge of how SMT solvers work or how different logics operate. The details are hidden behind the SBV framework, providing Haskell programmers with a clean API that is unencumbered by the details of individual solvers. To that end, we use the SMT-Lib standard (http://smtlib.cs.uiowa.edu/) to communicate with arbitrary SMT solvers.

A note on reasoning in the presence of quantifers

Note that SBV allows reasoning with quantifiers: Inputs can be existentially or universally quantified. Predicates can be built with arbitrary nesting of such quantifiers as well. However, SBV always assumes that the input is in prenex-normal form: http://en.wikipedia.org/wiki/Prenex_normal_form. That is, all the input declarations are treated as happening at the beginning of a predicate, followed by the actual formula. Unfortunately, the way predicates are written can be misleading at times, since symbolic inputs can be created at arbitrary points; interleaving them with other code. The rule is simple, however: All inputs are assumed at the top, in the order declared, regardless of their quantifiers. SBV will apply skolemization to get rid of existentials before sending predicates to backend solvers. However, if you do want nested quantification, you will manually have to first convert to prenex-normal form (which produces an equisatisfiable but not necessarily equivalent formula), and code that explicitly in SBV. See http://github.com/LeventErkok/sbv/issues/256 for a detailed discussion of this issue.

Using multiple solvers

On a multi-core machine, it might be desirable to try a given property using multiple SMT solvers, using parallel threads. Even with machines with single-cores, threading can be helpful if you want to try out multiple-solvers but do not know which one would work the best for the problem at hand ahead of time.

SBV allows proving/satisfiability-checking with multiple backends at the same time. Each function comes in two variants, one that returns the results from all solvers, the other that returns the fastest one.

The All variants, (i.e., proveWithAll, satWithAll) run all solvers and return all the results. SBV internally makes sure that the result is lazily generated; so, the order of solvers given does not matter. In other words, the order of results will follow the order of the solvers as they finish, not as given by the user. These variants are useful when you want to make sure multiple-solvers agree (or disagree!) on a given problem.

The Any variants, (i.e., proveWithAny, satWithAny) will run all the solvers in parallel, and return the results of the first one finishing. The other threads will then be killed. These variants are useful when you do not care if the solvers produce the same result, but rather want to get the solution as quickly as possible, taking advantage of modern many-core machines.

Note that the function sbvAvailableSolvers will return all the installed solvers, which can be used as the first argument to all these functions, if you simply want to try all available solvers on a machine.

type Predicate = Symbolic SBool

A predicate is a symbolic program that returns a (symbolic) boolean value. For all intents and purposes, it can be treated as an n-ary function from symbolic-values to a boolean. The Symbolic monad captures the underlying representation, and can/should be ignored by the users of the library, unless you are building further utilities on top of SBV itself. Instead, simply use the Predicate type when necessary.

type Goal = Symbolic ()

A goal is a symbolic program that returns no values. The idea is that the constraints/min-max goals will serve as appropriate directives for sat/prove calls.

type Provable = MProvable IO

Provable is specialization of MProvable to the IO monad. Unless you are using transformers explicitly, this is the type you should prefer.

forAll_ :: Provable a => a -> Symbolic SBool

Turns a value into a universally quantified predicate, internally naming the inputs. In this case the sbv library will use names of the form s1, s2, etc. to name these variables Example:

 forAll_ $ \(x::SWord8) y -> x `shiftL` 2 .== y

is a predicate with two arguments, captured using an ordinary Haskell function. Internally, x will be named s0 and y will be named s1.

NB. For a version which generalizes over the underlying monad, see forAll_

forAll :: Provable a => [String] -> a -> Symbolic SBool

Turns a value into a predicate, allowing users to provide names for the inputs. If the user does not provide enough number of names for the variables, the remaining ones will be internally generated. Note that the names are only used for printing models and has no other significance; in particular, we do not check that they are unique. Example:

 forAll ["x", "y"] $ \(x::SWord8) y -> x `shiftL` 2 .== y

This is the same as above, except the variables will be named x and y respectively, simplifying the counter-examples when they are printed.

NB. For a version which generalizes over the underlying monad, see forAll

forSome_ :: Provable a => a -> Symbolic SBool

Turns a value into an existentially quantified predicate. (Indeed, exists would have been a better choice here for the name, but alas it's already taken.)

NB. For a version which generalizes over the underlying monad, see forSome_

allSat :: Provable a => a -> IO AllSatResult

Find all satisfying assignments, using the default solver. Equivalent to allSatWith defaultSMTCfg. See allSatWith for details.

NB. For a version which generalizes over the underlying monad, see allSat

allSatWith :: Provable a => SMTConfig -> a -> IO AllSatResult

Return all satisfying assignments for a predicate. Note that this call will block until all satisfying assignments are found. If you have a problem with infinitely many satisfying models (consider SInteger) or a very large number of them, you might have to wait for a long time. To avoid such cases, use the allSatMaxModelCount parameter in the configuration.

NB. Uninterpreted constant/function values and counter-examples for array values are ignored for the purposes of allSat. That is, only the satisfying assignments modulo uninterpreted functions and array inputs will be returned. This is due to the limitation of not having a robust means of getting a function counter-example back from the SMT solver. Find all satisfying assignments using the given SMT-solver

Prove a property with multiple solvers, running them in separate threads. Only the result of the first one to finish will be returned, remaining threads will be killed. Note that we send a ThreadKilled to the losing processes, but we do *not* actually wait for them to finish. In rare cases this can lead to zombie processes. In previous experiments, we found that some processes take their time to terminate. So, this solution favors quick turnaround.

generateSMTBenchmark :: (MonadIO m, MProvable m a) => Bool -> a -> m String

Create an SMT-Lib2 benchmark. The Bool argument controls whether this is a SAT instance, i.e., translate the query directly, or a PROVE instance, i.e., translate the negated query.

solve :: [SBool] -> Symbolic SBool

Form the symbolic conjunction of a given list of boolean conditions. Useful in expressing problems with constraints, like the following:

  sat $ do [x, y, z] <- sIntegers ["x", "y", "z"]
           solve [x .> 5, y + z .< x]

NB. For a version which generalizes over the underlying monad, see solve

Constraints

A constraint is a means for restricting the input domain of a formula. Here's a simple example:

   do x <- exists "x"
      y <- exists "y"
      constrain $ x .> y
      constrain $ x + y .>= 12
      constrain $ y .>= 3
      ...

The first constraint requires x to be larger than y. The scond one says that sum of x and y must be at least 12, and the final one says that y to be at least 3. Constraints provide an easy way to assert additional properties on the input domain, right at the point of the introduction of variables.

Note that the proper reading of a constraint depends on the context:

• In a sat (or allSat) call: The constraint added is asserted conjunctively. That is, the resulting satisfying model (if any) will always satisfy all the constraints given.
• In a prove call: In this case, the constraint acts as an implication. The property is proved under the assumption that the constraint holds. In other words, the constraint says that we only care about the input space that satisfies the constraint.
• In a quickCheck call: The constraint acts as a filter for quickCheck; if the constraint does not hold, then the input value is considered to be irrelevant and is skipped. Note that this is similar to prove, but is stronger: We do not accept a test case to be valid just because the constraints fail on them, although semantically the implication does hold. We simply skip that test case as a bad test vector.
• In a genTest call: Similar to quickCheck and prove: If a constraint does not hold, the input value is ignored and is not included in the test set.

A good use case (in fact the motivating use case) for constrain is attaching a constraint to a forall or exists variable at the time of its creation. Also, the conjunctive semantics for sat and the implicative semantics for prove simplify programming by choosing the correct interpretation automatically. However, one should be aware of the semantic difference. For instance, in the presence of constraints, formulas that are provable are not necessarily satisfiable. To wit, consider:

   do x <- exists "x"
      constrain $ x .< x
      return $ x .< (x :: SWord8)

This predicate is unsatisfiable since no element of SWord8 is less than itself. But it's (vacuously) true, since it excludes the entire domain of values, thus making the proof trivial. Hence, this predicate is provable, but is not satisfiable. To make sure the given constraints are not vacuous, the functions isVacuous (and isVacuousWith) can be used.

Also note that this semantics imply that test case generation (genTest) and quick-check can take arbitrarily long in the presence of constraints, if the random input values generated rarely satisfy the constraints. (As an extreme case, consider constrain sFalse.)

constrain :: SolverContext m => SBool -> m ()

Add a constraint, any satisfying instance must satisfy this condition.

softConstrain :: SolverContext m => SBool -> m ()

Add a soft constraint. The solver will try to satisfy this condition if possible, but won't if it cannot.

Constraint Vacuity

When adding constraints, one has to be careful about making sure they are not inconsistent. The function isVacuous can be use for this purpose. Here is an example. Consider the following predicate:

>>> let pred = do { x <- free "x"; constrain $ x .< x; return $ x .>= (5 :: SWord8) }

This predicate asserts that all 8-bit values are larger than 5, subject to the constraint that the values considered satisfy x .< x, i.e., they are less than themselves. Since there are no values that satisfy this constraint, the proof will pass vacuously:

>>> prove pred
Q.E.D.

We can use isVacuous to make sure to see that the pass was vacuous:

>>> isVacuous pred
True

While the above example is trivial, things can get complicated if there are multiple constraints with non-straightforward relations; so if constraints are used one should make sure to check the predicate is not vacuously true. Here's an example that is not vacuous:

>>> let pred' = do { x <- free "x"; constrain $ x .> 6; return $ x .>= (5 :: SWord8) }

This time the proof passes as expected:

>>> prove pred'
Q.E.D.

And the proof is not vacuous:

>>> isVacuous pred'
False

Named constraints and attributes

Constraints can be given names:

 namedConstraint "a is at least 5" $ a .>= 5

Similarly, arbitrary term attributes can also be associated:

 constrainWithAttribute [(":solver-specific-attribute", "value")] $ a .>= 5

Note that a namedConstraint is equivalent to a constrainWithAttribute call, setting the `":named"' attribute.

namedConstraint :: SolverContext m => String -> SBool -> m ()

Add a named constraint. The name is used in unsat-core extraction.

constrainWithAttribute :: SolverContext m => [(String, String)] -> SBool -> m ()

Add a constraint, with arbitrary attributes. Used in interpolant generation.

Unsat cores

Named constraints are useful when used in conjunction with getUnsatCore function where the backend solver can be queried to obtain an unsat core in case the constraints are unsatisfiable. See getUnsatCore for details and Documentation.SBV.Examples.Queries.UnsatCore for an example use case.

Cardinality constraints

A pseudo-boolean function (http://en.wikipedia.org/wiki/Pseudo-Boolean_function) is a function from booleans to reals, basically treating True as 1 and False as 0. They are typically expressed in polynomial form. Such functions can be used to express cardinality constraints, where we want to count how many things satisfy a certain condition.

One can code such constraints using regular SBV programming: Simply walk over the booleans and the corresponding coefficients, and assert the required relation. For instance:

[b0, b1, b2, b3] `pbAtMost` 2

is precisely equivalent to:

sum (map (\b -> ite b 1 0) [b0, b1, b2, b3]) .<= 2

and they both express that at most two of b0, b1, b2, and b3 can be sTrue. However, the equivalent forms give rise to long formulas and the cardinality constraint can get lost in the translation. The idea here is that if you use these functions instead, SBV will produce better translations to SMTLib for more efficient solving of cardinality constraints, assuming the backend solver supports them. Currently, only Z3 supports pseudo-booleans directly. For all other solvers, SBV will translate these to equivalent terms that do not require special functions.

pbAtMost :: [SBool] -> Int -> SBool

sTrue if at most k of the input arguments are sTrue

pbAtLeast :: [SBool] -> Int -> SBool

sTrue if at least k of the input arguments are sTrue

pbExactly :: [SBool] -> Int -> SBool

sTrue if exactly k of the input arguments are sTrue

pbLe :: [(Int, SBool)] -> Int -> SBool

sTrue if the sum of coefficients for sTrue elements is at most k. Generalizes pbAtMost.

pbGe :: [(Int, SBool)] -> Int -> SBool

sTrue if the sum of coefficients for sTrue elements is at least k. Generalizes pbAtLeast.

pbEq :: [(Int, SBool)] -> Int -> SBool

sTrue if the sum of coefficients for sTrue elements is exactly least k. Useful for coding exactly K-of-N constraints, and in particular mutex constraints.

pbMutexed :: [SBool] -> SBool

sTrue if there is at most one set bit

pbStronglyMutexed :: [SBool] -> SBool

sTrue if there is exactly one set bit

Checking safety

The sAssert function allows users to introduce invariants to make sure certain properties hold at all times. This is another mechanism to provide further documentation/contract info into SBV code. The functions safe and safeWith can be used to statically discharge these proof assumptions. If a violation is found, SBV will print a model showing which inputs lead to the invariant being violated.

Here's a simple example. Let's assume we have a function that does subtraction, and requires its first argument to be larger than the second:

>>> let sub x y = sAssert Nothing "sub: x >= y must hold!" (x .>= y) (x - y)

Clearly, this function is not safe, as there's nothing that stops us from passing it a larger second argument. We can use safe to statically see if such a violation is possible before we use this function elsewhere.

>>> safe (sub :: SInt8 -> SInt8 -> SInt8)
[sub: x >= y must hold!: Violated. Model:
  s0 = 30 :: Int8
  s1 = 32 :: Int8]

What happens if we make sure to arrange for this invariant? Consider this version:

>>> let safeSub x y = ite (x .>= y) (sub x y) 0

Clearly, safeSub must be safe. And indeed, SBV can prove that:

>>> safe (safeSub :: SInt8 -> SInt8 -> SInt8)
[sub: x >= y must hold!: No violations detected]

Note how we used sub and safeSub polymorphically. We only need to monomorphise our types when a proof attempt is done, as we did in the safe calls.

If required, the user can pass a CallStack through the first argument to sAssert, which will be used by SBV to print a diagnostic info to pinpoint the failure.

Also see Documentation.SBV.Examples.Misc.NoDiv0 for the classic div-by-zero example.

sAssert :: HasKind a => Maybe CallStack -> String -> SBool -> SBV a -> SBV a

Symbolic assert. Check that the given boolean condition is always sTrue in the given path. The optional first argument can be used to provide call-stack info via GHC's location facilities.

isSafe :: SafeResult -> Bool

Check if a safe-call was safe or not, turning a SafeResult to a Bool.

class ExtractIO m => SExecutable m a

Symbolically executable program fragments. This class is mainly used for safe calls, and is sufficently populated internally to cover most use cases. Users can extend it as they wish to allow safe checks for SBV programs that return/take types that are user-defined.

Quick-checking

sbvQuickCheck :: Symbolic SBool -> IO Bool

Quick check an SBV property. Note that a regular quickCheck call will work just as well. Use this variant if you want to receive the boolean result.

Optimization

SBV can optimize metric functions, i.e., those that generate both bounded SIntN, SWordN, and unbounded SInteger types, along with those produce SReals. That is, it can find models satisfying all the constraints while minimizing or maximizing user given metrics. Currently, optimization requires the use of the z3 SMT solver as the backend, and a good review of these features is given in this paper: http://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/nbjorner-scss2014.pdf.

Goals can be lexicographically (default), independently, or pareto-front optimized. The relevant functions are:

• minimize: Minimize a given arithmetic goal
• maximize: Minimize a given arithmetic goal

Goals can be optimized at a regular or an extended value: An extended value is either positive or negative infinity (for unbounded integers and reals) or positive or negative epsilon differential from a real value (for reals).

For instance, a call of the form

 minimize "name-of-goal" $ x + 2*y

minimizes the arithmetic goal x+2*y, where x and y can be signed/unsigned bit-vectors, reals, or integers.

A simple example

Here's an optimization example in action:

>>> optimize Lexicographic $ \x y -> minimize "goal" (x+2*(y::SInteger))
Optimal in an extension field:
  goal = -oo :: Integer

We will describe the role of the constructor Lexicographic shortly.

Of course, this becomes more useful when the result is not in an extension field:

>>> :{
    optimize Lexicographic $ do
                  x <- sInteger "x"
                  y <- sInteger "y"
                  constrain $ x .> 0
                  constrain $ x .< 6
                  constrain $ y .> 2
                  constrain $ y .< 12
                  minimize "goal" $ x + 2 * y
    :}
Optimal model:
  x    = 1 :: Integer
  y    = 3 :: Integer
  goal = 7 :: Integer

As usual, the programmatic API can be used to extract the values of objectives and model-values (getModelObjectives, getModelAssignment, etc.) to access these values and program with them further.

The following examples illustrate the use of basic optimization routines:

• Documentation.SBV.Examples.Optimization.LinearOpt: Simple linear-optimization example.
• Documentation.SBV.Examples.Optimization.Production: Scheduling machines in a shop
• Documentation.SBV.Examples.Optimization.VM: Scheduling virtual-machines in a data-center

Multiple optimization goals

Multiple goals can be specified, using the same syntax. In this case, the user gets to pick what style of optimization to perform, by passing the relevant OptimizeStyle as the first argument to optimize.

• [Lexicographic]. The solver will optimize the goals in the given order, optimizing the latter ones under the model that optimizes the previous ones.
• [Independent]. The solver will optimize the goals independently of each other. In this case the user will be presented a model for each goal given.
• [Pareto]. Finally, the user can query for pareto-fronts. A pareto front is an model such that no goal can be made "better" without making some other goal "worse."

Pareto fronts only make sense when the objectives are bounded. If there are unbounded objective values, then the backend solver can loop infinitely. (This is what z3 does currently.) If you are not sure the objectives are bounded, you should first use Independent mode to ensure the objectives are bounded, and then switch to pareto-mode to extract them further.

The optional number argument to Pareto specifies the maximum number of pareto-fronts the user is asking to get. If Nothing, SBV will query for all pareto-fronts. Note that pareto-fronts can be really large, so if Nothing is used, there is a potential for waiting indefinitely for the SBV-solver interaction to finish. (If you suspect this might be the case, run in verbose mode to see the interaction and put a limiting factor appropriately.)

data OptimizeStyle

Style of optimization. Note that in the pareto case the user is allowed to specify a max number of fronts to query the solver for, since there might potentially be an infinite number of them and there is no way to know exactly how many ahead of time. If Nothing is given, SBV will possibly loop forever if the number is really infinite.

Constructors

Lexicographic

Objectives are optimized in the order given, earlier objectives have higher priority.

Independent

Each objective is optimized independently.

Pareto (Maybe Int)

Objectives are optimized according to pareto front: That is, no objective can be made better without making some other worse.

class Metric a where

Class of metrics we can optimize for. Currently, booleans, bounded signed/unsigned bit-vectors, unbounded integers, algebraic reals and floats can be optimized. You can add your instances, but bewared that the MetricSpace should map your type to something the backend solver understands, which are limited to unsigned bit-vectors, reals, and unbounded integers for z3.

A good reference on these features is given in the following paper: http://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/nbjorner-scss2014.pdf.

Minimal completion: None. However, if MetricSpace is not identical to the type, you want to define toMetricSpace and possibly 'minimize'/'maximize' to add extra constraints as necessary.

Soft assertions

Related to optimization, SBV implements soft-asserts via assertWithPenalty calls. A soft assertion is a hint to the SMT solver that we would like a particular condition to hold if **possible*. That is, if there is a solution satisfying it, then we would like it to hold, but it can be violated if there is no way to satisfy it. Each soft-assertion can be associated with a numeric penalty for not satisfying it, hence turning it into an optimization problem.

Note that assertWithPenalty works well with optimization goals ('minimize'/'maximize' etc.), and are most useful when we are optimizing a metric and thus some of the constraints can be relaxed with a penalty to obtain a good solution. Again see http://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/nbjorner-scss2014.pdf for a good overview of the features in Z3 that SBV is providing the bridge for.

A soft assertion can be specified in one of the following three main ways:

         assertWithPenalty "bounded_x" (x .< 5) DefaultPenalty
         assertWithPenalty "bounded_x" (x .< 5) (Penalty 2.3 Nothing)
         assertWithPenalty "bounded_x" (x .< 5) (Penalty 4.7 (Just "group-1"))

In the first form, we are saying that the constraint x .< 5 must be satisfied, if possible, but if this constraint can not be satisfied to find a model, it can be violated with the default penalty of 1.

In the second case, we are associating a penalty value of 2.3.

Finally in the third case, we are also associating this constraint with a group. The group name is only needed if we have classes of soft-constraints that should be considered together.

Introduce a soft assertion, with an optional penalty

NB. For a version which generalizes over the underlying monad, see assertWithPenalty

Model extraction

The default Show instances for prover calls provide all the counter-example information in a human-readable form and should be sufficient for most casual uses of sbv. However, tools built on top of sbv will inevitably need to look into the constructed models more deeply, programmatically extracting their results and performing actions based on them. The API provided in this section aims at simplifying this task.

Inspecting proof results

ThmResult, SatResult, and AllSatResult are simple newtype wrappers over SMTResult. Their main purpose is so that we can provide custom Show instances to print results accordingly.

Observing expressions

The observe command can be used to trace values of arbitrary expressions during a sat, prove, or perhaps more importantly, in a quickCheck call with the sObserve variant.. This is useful for, for instance, recording expected vs. obtained expressions as a symbolic program is executing.

>>> :{
prove $ do a1 <- free "i1"
           a2 <- free "i2"
           let spec, res :: SWord8
               spec = a1 + a2
               res  = ite (a1 .== 12 .&& a2 .== 22)   -- insert a malicious bug!
                          1
                          (a1 + a2)
           return $ observe "Expected" spec .== observe "Result" res
:}
Falsifiable. Counter-example:
  Expected = 34 :: Word8
  Result   =  1 :: Word8
  i1       = 12 :: Word8
  i2       = 22 :: Word8

The observeIf variant allows the user to specify a boolean condition when the value is interesting to observe. Useful when you have lots of "debugging" points, but not all are of interest. Use the sObserve variant when you are at the Symbolic monad, which also supports quick-check applications.

observe :: SymVal a => String -> SBV a -> SBV a

Observe the value of an expression, uncoditionally. See observeIf for a generalized version.

observeIf :: SymVal a => (a -> Bool) -> String -> SBV a -> SBV a

Observe the value of an expression, if the given condition holds. Such values are useful in model construction, as they are printed part of a satisfying model, or a counter-example. The same works for quick-check as well. Useful when we want to see intermediate values, or expected/obtained pairs in a particular run. Note that an observed expression is always symbolic, i.e., it won't be constant folded. Compare this to label which is used for putting a label in the generated SMTLib-C code.

sObserve :: SymVal a => String -> SBV a -> Symbolic ()

A variant of observe that you can use at the top-level. This is useful with quick-check, for instance.

Programmable model extraction

While default Show instances are sufficient for most use cases, it is sometimes desirable (especially for library construction) that the SMT-models are reinterpreted in terms of domain types. Programmable extraction allows getting arbitrarily typed models out of SMT models.

class SatModel a where

Instances of SatModel can be automatically extracted from models returned by the solvers. The idea is that the sbv infrastructure provides a stream of CV's (constant values) coming from the solver, and the type a is interpreted based on these constants. Many typical instances are already provided, so new instances can be declared with relative ease.

Methods

modelExists :: a -> Bool

Is there a model?

getModelAssignment :: SatModel b => a -> Either String (Bool, b)

Extract assignments of a model, the result is a tuple where the first argument (if True) indicates whether the model was "probable". (i.e., if the solver returned unknown.)

getModelDictionary :: a -> Map String CV

Extract a model dictionary. Extract a dictionary mapping the variables to their respective values as returned by the SMT solver. Also see getModelDictionaries.

getModelValue :: SymVal b => String -> a -> Maybe b

Extract a model value for a given element. Also see getModelValues.

getModelUninterpretedValue :: String -> a -> Maybe String

displayModels :: SatModel a => (Int -> (Bool, a) -> IO ()) -> AllSatResult -> IO Int

Given an allSat call, we typically want to iterate over it and print the results in sequence. The displayModels function automates this task by calling disp on each result, consecutively. The first Int argument to disp 'is the current model number. The second argument is a tuple, where the first element indicates whether the model is alleged (i.e., if the solver is not sure, returing Unknown)

extractModels :: SatModel a => AllSatResult -> [a]

Return all the models from an allSat call, similar to extractModel but is suitable for the case of multiple results.

getModelDictionaries :: AllSatResult -> [Map String CV]

Get dictionaries from an all-sat call. Similar to getModelDictionary.

getModelValues :: SymVal b => String -> AllSatResult -> [Maybe b]

Extract value of a variable from an all-sat call. Similar to getModelValue.

getModelUninterpretedValues :: String -> AllSatResult -> [Maybe String]

Extract value of an uninterpreted variable from an all-sat call. Similar to getModelUninterpretedValue.

SMT Interface

data SMTConfig

Solver configuration. See also z3, yices, cvc4, boolector, mathSAT, etc. which are instantiations of this type for those solvers, with reasonable defaults. In particular, custom configuration can be created by varying those values. (Such as z3{verbose=True}.)

Most fields are self explanatory. The notion of precision for printing algebraic reals stems from the fact that such values does not necessarily have finite decimal representations, and hence we have to stop printing at some depth. It is important to emphasize that such values always have infinite precision internally. The issue is merely with how we print such an infinite precision value on the screen. The field printRealPrec controls the printing precision, by specifying the number of digits after the decimal point. The default value is 16, but it can be set to any positive integer.

When printing, SBV will add the suffix ... at the and of a real-value, if the given bound is not sufficient to represent the real-value exactly. Otherwise, the number will be written out in standard decimal notation. Note that SBV will always print the whole value if it is precise (i.e., if it fits in a finite number of digits), regardless of the precision limit. The limit only applies if the representation of the real value is not finite, i.e., if it is not rational.

The printBase field can be used to print numbers in base 2, 10, or 16. If base 2 or 16 is used, then floating-point values will be printed in their internal memory-layout format as well, which can come in handy for bit-precise analysis.

Controlling verbosity

SBV provides various levels of verbosity to aid in debugging, by using the SMTConfig fields:

• [verbose] Print on stdout a shortened account of what is sent/received. This is specifically trimmed to reduce noise and is good for quick debugging. The output is not supposed to be machine-readable.
• [redirectVerbose] Send the verbose output to a file. Note that you still have to set `verbose=True` for redirection to take effect. Otherwise, the output is the same as what you would see in verbose.
• [transcript] Produce a file that is valid SMTLib2 format, containing everything sent and received. In particular, one can directly feed this file to the SMT-solver outside of the SBV since it is machine-readable. This is good for offline analysis situations, where you want to have a full account of what happened. For instance, it will print time-stamps at every interaction point, so you can see how long each command took.

class HasKind a where

A class for capturing values that have a sign and a size (finite or infinite) minimal complete definition: kindOf, unless you can take advantage of the default signature: This class can be automatically derived for data-types that have a Data instance; this is useful for creating uninterpreted sorts. So, in reality, end users should almost never need to define any methods.

label :: SymVal a => String -> SBV a -> SBV a

label: Label the result of an expression. This is essentially a no-op, but useful as it generates a comment in the generated C/SMT-Lib code. Note that if the argument is a constant, then the label is dropped completely, per the usual constant folding strategy. Compare this to observe which is good for printing counter-examples.

output :: Outputtable a => a -> Symbolic a

Mark an interim result as an output. Useful when constructing Symbolic programs that return multiple values, or when the result is programmatically computed.

Run an arbitrary symbolic computation, equivalent to runSMTWith defaultSMTCfg

NB. For a version which generalizes over the underlying monad, see runSMT

runSMTWith :: SMTConfig -> Symbolic a -> IO a

Runs an arbitrary symbolic computation, exposed to the user in SAT mode
