    (i1,b1) = unbundle (mealy clk rst en f 0 (bundle (a,b)))

A version of moore that does automatic Bundleing

Given a functions t and o of types:

When we want to make compositions of t and o in g using moore, we have to write:

g clk rst en a b c = (b1,b2,i2)
  where
    (i1,b1) = unbundle (moore clk rst en t o 0 (bundle (a,b)))
    (i2,b2) = unbundle (moore clk rst en t o 3 (bundle (c,i1)))

Using mooreB however we can write:

g clk rst en a b c = (b1,b2,i2)
  where
    (i1,b1) = mooreB clk rst en t o 0 (a,b)
    (i2,b2) = mooreB clk rst en t o 3 (c,i1)

registerB :: (KnownDomain dom, NFDataX a, Bundle a) => Clock dom -> Reset dom -> Enable dom -> a -> Unbundled dom a -> Unbundled dom a

Synchronizer circuits for safe clock domain crossings

dualFlipFlopSynchronizer

Arguments

:: (NFDataX a, KnownDomain dom1, KnownDomain dom2)

=> Clock dom1

Clock to which the incoming data is synchronized

-> Clock dom2

Clock to which the outgoing data is synchronized

-> Reset dom2

Reset for registers on the outgoing domain

-> Enable dom2

Enable for registers on the outgoing domain

-> a

Initial value of the two synchronization registers

-> Signal dom1 a

Incoming data

-> Signal dom2 a

Outgoing, synchronized, data

Synchronizer based on two sequentially connected flip-flops.

• NB: This synchronizer can be used for bit-synchronization.

• NB: Although this synchronizer does reduce metastability, it does not guarantee the proper synchronization of a whole word. For example, given that the output is sampled twice as fast as the input is running, and we have two samples in the input stream that look like:

  [0111,1000]

  But the circuit driving the input stream has a longer propagation delay on msb compared to the lsbs. What can happen is an output stream that looks like this:

  [0111,0111,0000,1000]

  Where the level-change of the msb was not captured, but the level change of the lsbs were.

  If you want to have safe word-synchronization use asyncFIFOSynchronizer.

asyncFIFOSynchronizer

Arguments

:: (KnownDomain wdom, KnownDomain rdom, 2 <= addrSize, NFDataX a)

=> SNat addrSize

Size of the internally used addresses, the FIFO contains 2^addrSize elements.

-> Clock wdom

Clock to which the write port is synchronized

-> Clock rdom

Clock to which the read port is synchronized

-> Reset wdom

-> Reset rdom

-> Enable wdom

-> Enable rdom

-> Signal rdom Bool

Read request

-> Signal wdom (Maybe a)

Element to insert

-> (Signal rdom a, Signal rdom Bool, Signal wdom Bool)

(Oldest element in the FIFO, empty flag, full flag)

Synchronizer implemented as a FIFO around a synchronous RAM. Based on the design described in Clash.Tutorial, which is itself based on the design described in http://www.sunburst-design.com/papers/CummingsSNUG2002SJ_FIFO1.pdf. However, this FIFO uses a synchronous dual-ported RAM which, unlike those designs using RAM with an asynchronous read port, is nearly guaranteed to actually synthesize into one of the dual-ported RAMs found on most FPGAs.

NB: This synchronizer can be used for word-synchronization. NB: This synchronizer will only work safely when you set up the proper bus skew and maximum delay constraints inside your synthesis tool for the clock domain crossings of the gray pointers.

createMemBlob

Arguments

:: forall a f. (Foldable f, BitPack a)

=> String

Name of the binding to generate

-> Maybe Bit

Value to map don't care bits to. Nothing means throwing an error on don't care bits.

-> f a

The content for the MemBlob

-> DecsQ

Create a MemBlob binding from a list of values

Since this uses Template Haskell, nothing in the arguments given to createMemBlob can refer to something defined in the same module.

Example

createMemBlob "content" Nothing [15 :: Unsigned 8 .. 17]

ram clk en = blockRamBlob clk en content

The Maybe datatype has don't care bits, where the actual value does not matter. But the bits need a defined value in the memory. Either 0 or 1 can be used, and both are valid representations of the data.

>>> import qualified Prelude as P
>>> let es = [ Nothing, Just (7 :: Unsigned 8), Just 8 ]
>>> :{
createMemBlob "content0" (Just 0) es
createMemBlob "content1" (Just 1) es
x = 1
:}

>>> let pr = mapM_ (putStrLn . show)
>>> pr $ P.map pack es
0b0_...._....
0b1_0000_0111
0b1_0000_1000
>>> pr $ unpackMemBlob content0
0b0_0000_0000
0b1_0000_0111
0b1_0000_1000
>>> pr $ unpackMemBlob content1
0b0_1111_1111
0b1_0000_0111
0b1_0000_1000
>>> :{
createMemBlob "contentN" Nothing es
x = 1
:}

<interactive>:...: error:...
    packBVs: cannot convert don't care values. Please specify a mapping to a definite value.

Note how we hinted to clashi that our multi-line command was a list of declarations by including a dummy declaration x = 1. Without this trick, clashi would expect an expression and the Template Haskell would not work.

memBlobTH

Arguments

:: forall a f. (Foldable f, BitPack a)

=> Maybe Bit

Value to map don't care bits to. Nothing means throwing an error on don't care bits.

-> f a

The content for the MemBlob

-> ExpQ

Create a MemBlob from a list of values

Since this uses Template Haskell, nothing in the arguments given to memBlobTH can refer to something defined in the same module.

Example

ram clk en = blockRamBlob clk en $(memBlobTH Nothing [15 :: Unsigned 8 .. 17])

The Maybe datatype has don't care bits, where the actual value does not matter. But the bits need a defined value in the memory. Either 0 or 1 can be used, and both are valid representations of the data.

>>> import qualified Prelude as P
>>> let es = [ Nothing, Just (7 :: Unsigned 8), Just 8 ]
>>> content0 = $(memBlobTH (Just 0) es)
>>> content1 = $(memBlobTH (Just 1) es)
>>> let pr = mapM_ (putStrLn . show)
>>> pr $ P.map pack es
0b0_...._....

Outputs data on next cycle. When writing, the data written will be echoed. When reading, the read data is returned.

Produces vendor-agnostic HDL that will be inferred as a true dual-port block RAM

Any value that is being written on a particular port is also the value that will be read on that port, i.e. the same-port read/write behavior is: WriteFirst. For mixed-port read/write, when port A writes to the address port B reads from, the output of port B is undefined, and vice versa.

isRising

Arguments

:: (KnownDomain dom, NFDataX a, Bounded a, Eq a)

=> Clock dom

-> Reset dom

-> Enable dom

-> a

Starting value

-> Signal dom a

-> Signal dom Bool

Give a pulse when the Signal goes from minBound to maxBound

isFalling

Arguments

:: (KnownDomain dom, NFDataX a, Bounded a, Eq a)

=> Clock dom

-> Reset dom

-> Enable dom

-> a

Starting value

-> Signal dom a

-> Signal dom Bool

Give a pulse when the Signal goes from maxBound to minBound

riseEvery :: forall dom n. KnownDomain dom => Clock dom -> Reset dom -> Enable dom -> SNat n -> Signal dom Bool

Give a pulse every n clock cycles. This is a useful helper function when combined with functions like regEn or mux, in order to delay a register by a known amount.

oscillate :: forall dom n. KnownDomain dom => Clock dom -> Reset dom -> Enable dom -> Bool -> SNat n -> Signal dom Bool

Oscillate a Bool for a given number of cycles, given the starting state.

Testbench functions

assert

Arguments

:: (KnownDomain dom, Eq a, ShowX a)

=> Clock dom

-> Reset dom

-> String

Additional message

-> Signal dom a

Checked value

-> Signal dom a

Expected value

-> Signal dom b

Return value

-> Signal dom b

Compares the first two Signals for equality and logs a warning when they are not equal. The second Signal is considered the expected value. This function simply returns the third Signal unaltered as its result. This function is used by outputVerifier.

Usage in clashi

NB: When simulating a component that uses assert in clashi, usually, the warnings are only logged the first time the component is simulated. Issuing :reload in clashi will discard the cached result of the computation, and warnings will once again be emitted.

NB: This function can be used in synthesizable designs.

=> Clock dom

Clock to which to synchronize the output signal

-> Reset dom

  -> Reset dom
  -> Signal dom Int
testInput clk rst = stimuliGenerator clk rst $(listToVecTH [(1::Int),3..21])

>>> sampleN 14 (testInput systemClockGen resetGen)

=> Clock dom

Clock to which the test bench is synchronized

-> Reset dom

-> Vec l a

Samples to compare with

-> Signal dom a

Signal to verify

-> Signal dom Bool

Indicator that all samples are verified

Same as outputVerifier but used in cases where the test bench domain and the domain of the circuit under test are the same.

Tracing

Simple

traceSignal1

Arguments

:: (BitPack a, NFDataX a, Typeable a)

=> String

Name of signal in the VCD output

-> Signal dom a

Signal to trace

-> Signal dom a

Trace a single signal. Will emit an error if a signal with the same name was previously registered.

NB: Associates the traced signal with a clock period of 1, which results in incorrect VCD files when working with circuits that have multiple clocks. Use traceSignal when working with circuits that have multiple clocks.

traceVecSignal1

Arguments

:: (KnownNat n, BitPack a, NFDataX a, Typeable a)

=> String

Name of signal in debugging output. Will be appended by _0, _1, ..., _n.

-> Signal dom (Vec (n + 1) a)

Signal to trace

-> Signal dom (Vec (n + 1) a)

Trace a single vector signal: each element in the vector will show up as a different trace. If the trace name already exists, this function will emit an error.

NB: Associates the traced signal with a clock period of 1, which results in incorrect VCD files when working with circuits that have multiple clocks. Use traceSignal when working with circuits that have multiple clocks.

Tracing in a multi-clock environment

traceSignal

Arguments

:: forall dom a. (KnownDomain dom, BitPack a, NFDataX a, Typeable a)

=> String

Name of signal in the VCD output

-> Signal dom a

Signal to trace

-> Signal dom a

Trace a single signal. Will emit an error if a signal with the same name was previously registered.

NB: Works correctly when creating VCD files from traced signal in multi-clock circuits. However traceSignal1 might be more convenient to use when the domain of your circuit is polymorphic.

traceVecSignal

Arguments

:: forall dom a n. (KnownDomain dom, KnownNat n, BitPack a, NFDataX a, Typeable a)

=> String

Name of signal in debugging output. Will be appended by _0, _1, ..., _n.

-> Signal dom (Vec (n + 1) a)

Signal to trace

-> Signal dom (Vec (n + 1) a)

Trace a single vector signal: each element in the vector will show up as a different trace. If the trace name already exists, this function will emit an error.

NB: Works correctly when creating VCD files from traced signal in multi-clock circuits. However traceSignal1 might be more convenient to use when the domain of your circuit is polymorphic.

VCD dump functions

dumpVCD

Arguments

:: NFDataX a

=> (Int, Int)

(offset, number of samples)

-> Signal dom a

(One of) the outputs of the circuit containing the traces

-> [String]

The names of the traces you definitely want to be dumped in the VCD file

-> IO (Either String Text)

Produce a four-state VCD (Value Change Dump) according to IEEE 1364-{1995,2001}. This function fails if a trace name contains either non-printable or non-VCD characters.

Due to lazy evaluation, the created VCD files might not contain all the traces you were expecting. You therefore have to provide a list of names you definately want to be dumped in the VCD file.

For example:

vcd <- dumpVCD (0, 100) cntrOut ["main", "sub"]

Evaluates cntrOut long enough in order for to guarantee that the main, and sub traces end up in the generated VCD file.

foldl :: (b -> a -> b) -> b -> Vec n a -> b

foldl, applied to a binary operator, a starting value (typically the left-identity of the operator), and a vector, reduces the vector using the binary operator, from left to right:

foldl f z (x1 :> x2 :> ... :> xn :> Nil) == (...((z `f` x1) `f` x2) `f`...) `f` xn
foldl f z Nil                            == z

>>> foldl (/) 1 (5 :> 4 :> 3 :> 2 :> Nil)
8.333333333333333e-3

"foldl f z xs" corresponds to the following circuit layout:

NB: "foldl f z xs" produces a linear structure, which has a depth, or delay, of O(length xs). Use fold if your binary operator f is associative, as "fold f xs" produces a structure with a depth of O(log_2(length xs)).

foldr :: (a -> b -> b) -> b -> Vec n a -> b

foldr, applied to a binary operator, a starting value (typically the right-identity of the operator), and a vector, reduces the vector using the binary operator, from right to left:

foldr f z (x1 :> ... :> xn1 :> xn :> Nil) == x1 `f` (... (xn1 `f` (xn `f` z))...)
foldr r z Nil                             == z

What you should use when your vector functions are too strict in their arguments.

doctests setup

>>> let compareSwapL a b = if a < b then (a,b) else (b,a)
>>> :{
let sortVL :: (Ord a, KnownNat (n + 1)) => Vec ((n + 1) + 1) a -> Vec ((n + 1) + 1) a
    sortVL xs = map fst sorted :< (snd (last sorted))
      where
        lefts  = head xs :> map snd (init sorted)
        rights = tail xs
        sorted = zipWith compareSwapL (lazyV lefts) rights
:}

>>> :{
let sortV_flip xs = map fst sorted :< (snd (last sorted))
      where
        lefts  = head xs :> map snd (init sorted)
        rights = tail xs
        sorted = zipWith (flip compareSwapL) rights lefts
:}

Example usage

For example:

-- Bubble sort for 1 iteration
sortV xs = map fst sorted :< (snd (last sorted))
 where
   lefts  = head xs :> map snd (init sorted)
   rights = tail xs
   sorted = zipWith compareSwapL lefts rights

-- Compare and swap
compareSwapL a b = if a < b then (a,b)
                            else (b,a)

Will not terminate because zipWith is too strict in its second argument.

In this case, adding lazyV on zipWiths second argument:

sortVL xs = map fst sorted :< (snd (last sorted))
 where
   lefts  = head xs :> map snd (init sorted)
   rights = tail xs
   sorted = zipWith compareSwapL (lazyV lefts) rights

Results in a successful computation:

>>> sortVL (4 :> 1 :> 2 :> 3 :> Nil)
1 :> 2 :> 3 :> 4 :> Nil

NB: There is also a solution using flip, but it slightly obfuscates the meaning of the code:

sortV_flip xs = map fst sorted :< (snd (last sorted))
 where
   lefts  = head xs :> map snd (init sorted)
   rights = tail xs
   sorted = zipWith (flip compareSwapL) rights lefts

>>> sortV_flip (4 :> 1 :> 2 :> 3 :> Nil)
1 :> 2 :> 3 :> 4 :> Nil

dfold

Arguments

:: forall p k a. KnownNat k

=> Proxy (p :: TyFun Nat Type -> Type)

The motive

-> (forall l. SNat l -> a -> (p @@ l) -> p @@ (l + 1))

Function to fold.

NB: The SNat l is not the index (see (!!)) to the element a. SNat l is the number of elements that occur to the right of a.

-> (p @@ 0)

Initial element

-> Vec k a

Vector to fold over

-> p @@ k

A dependently typed fold.

doctests setup

>>> :seti -fplugin GHC.TypeLits.Normalise
>>> import Data.Singletons (Apply, Proxy (..), TyFun)
>>> data Append (m :: Nat) (a :: Type) (f :: TyFun Nat Type) :: Type
>>> type instance Apply (Append m a) l = Vec (l + m) a
>>> let append' xs ys = dfold (Proxy :: Proxy (Append m a)) (const (:>)) ys xs

Example usage

Using lists, we can define append (a.k.a. Data.List.++) in terms of Data.List.foldr:

>>> import qualified Data.List
>>> let append xs ys = Data.List.foldr (:) ys xs
>>> append [1,2] [3,4]
[1,2,3,4]

However, when we try to do the same for Vec, by defining append' in terms of Clash.Sized.Vector.foldr:

append' xs ys = foldr (:>) ys xs

we get a type error:

>>> let append' xs ys = foldr (:>) ys xs

<interactive>:...
    • Occurs check: cannot construct the infinite type: ... ~ ... + 1
      Expected type: a -> Vec ... a -> Vec ... a
        Actual type: a -> Vec ... a -> Vec (... + 1) a
    • In the first argument of ‘foldr’, namely ‘(:>)’
      In the expression: foldr (:>) ys xs
      In an equation for ‘append'’: append' xs ys = foldr (:>) ys xs
    • Relevant bindings include
        ys :: Vec ... a (bound at ...)
        append' :: Vec n a -> Vec ... a -> Vec ... a
          (bound at ...)

The reason is that the type of foldr is:

>>> :t foldr
foldr :: (a -> b -> b) -> b -> Vec n a -> b

While the type of (:>) is:

>>> :t (:>)
(:>) :: a -> Vec n a -> Vec (n + 1) a

We thus need a fold function that can handle the growing vector type: dfold. Compared to foldr, dfold takes an extra parameter, called the motive, that allows the folded function to have an argument and result type that depends on the current length of the vector. Using dfold, we can now correctly define append':

import Data.Singletons
import Data.Proxy

data Append (m :: Nat) (a :: Type) (f :: TyFun Nat Type) :: Type
type instance Apply (Append m a) l = Vec (l + m) a

append' xs ys = dfold (Proxy :: Proxy (Append m a)) (const (:>)) ys xs

We now see that append' has the appropriate type:

>>> :t append'
append' :: KnownNat k => Vec k a -> Vec m a -> Vec (k + m) a

And that it works:

>>> append' (1 :> 2 :> Nil) (3 :> 4 :> Nil)
1 :> 2 :> 3 :> 4 :> Nil

NB: "dfold m f z xs" creates a linear structure, which has a depth, or delay, of O(length xs). Look at dtfold for a dependently typed fold that produces a structure with a depth of O(log_2(length xs)).

dtfold

Arguments

:: forall p k a. KnownNat k

=> Proxy (p :: TyFun Nat Type -> Type)

The motive

-> (a -> p @@ 0)

Function to apply to every element

-> (forall l. SNat l -> (p @@ l) -> (p @@ l) -> p @@ (l + 1))

Function to combine results.

NB: The SNat l indicates the depth/height of the node in the tree that is created by applying this function. The leafs of the tree have depth/height 0, and the root of the tree has height k.

-> Vec (2 ^ k) a

Vector to fold over.

NB: Must have a length that is a power of 2.

-> p @@ k

A combination of dfold and fold: a dependently typed fold that reduces a vector in a tree-like structure.

Example usage

As an example of when you might want to use dtfold we will build a population counter: a circuit that counts the number of bits set to '1' in a BitVector. Given a vector of n bits, we only need we need a data type that can represent the number n: Index (n+1). Index k has a range of [0 .. k-1] (using ceil(log2(k)) bits), hence we need Index n+1. As an initial attempt we will use sum, because it gives a nice (log2(n)) tree-structure of adders:

populationCount :: (KnownNat (n+1), KnownNat (n+2))
                => BitVector (n+1) -> Index (n+2)
populationCount = sum . map fromIntegral . bv2v

The "problem" with this description is that all adders have the same bit-width, i.e. all adders are of the type:

(+) :: Index (n+2) -> Index (n+2) -> Index (n+2).

This is a "problem" because we could have a more efficient structure: one where each layer of adders is precisely wide enough to count the number of bits at that layer. That is, at height d we want the adder to be of type:

Index ((2^d)+1) -> Index ((2^d)+1) -> Index ((2^(d+1))+1)

We have such an adder in the form of the add function, as defined in the instance ExtendingNum instance of Index. However, we cannot simply use fold to create a tree-structure of addes:

>>> :{
let populationCount' :: (KnownNat (n+1), KnownNat (n+2))
                     => BitVector (n+1) -> Index (n+2)
    populationCount' = fold add . map fromIntegral . bv2v
:}

<interactive>:...
    • Couldn't match type ‘((n + 2) + (n + 2)) - 1’ with ‘n + 2’
      Expected type: Index (n + 2) -> Index (n + 2) -> Index (n + 2)
        Actual type: Index (n + 2)
                     -> Index (n + 2) -> AResult (Index (n + 2)) (Index (n + 2))
    • In the first argument of ‘fold’, namely ‘add’
      In the first argument of ‘(.)’, namely ‘fold add’
      In the expression: fold add . map fromIntegral . bv2v
    • Relevant bindings include
        populationCount' :: BitVector (n + 1) -> Index (n + 2)
          (bound at ...)

because fold expects a function of type "a -> a -> a", i.e. a function where the arguments and result all have exactly the same type.

In order to accommodate the type of our add, where the result is larger than the arguments, we must use a dependently typed fold in the form of dtfold:

{-# LANGUAGE UndecidableInstances #-}
import Data.Singletons
import Data.Proxy

data IIndex (f :: TyFun Nat Type) :: Type
type instance Apply IIndex l = Index ((2^l)+1)

populationCount' :: (KnownNat k, KnownNat (2^k))
                 => BitVector (2^k) -> Index ((2^k)+1)
populationCount' bv = dtfold (Proxy @IIndex)
                             fromIntegral
                             (\_ x y -> add x y)
                             (bv2v bv)

And we can test that it works:

>>> :t populationCount' (7 :: BitVector 16)
populationCount' (7 :: BitVector 16) :: Index 17
>>> populationCount' (7 :: BitVector 16)
3

Some final remarks:

• By using dtfold instead of fold, we had to restrict our BitVector argument to have bit-width that is a power of 2.
• Even though our original populationCount function specified a structure where all adders had the same width. Most VHDL/(System)Verilog synthesis tools will create a more efficient circuit, i.e. one where the adders have an increasing bit-width for every layer, from the VHDL/(System)Verilog produced by the Clash compiler.

NB: The depth, or delay, of the structure produced by "dtfold m f g xs" is O(log_2(length xs)).

vfold :: forall k a b. KnownNat k => (forall l. SNat l -> a -> Vec l b -> Vec (l + 1) b) -> Vec k a -> Vec k b

Specialised version of dfold that builds a triangular computational structure.

doctests setup

>>> let compareSwap a b = if a > b then (a,b) else (b,a)
>>> let insert y xs = let (y',xs') = mapAccumL compareSwap y xs in xs' :< y'
>>> let insertionSort = vfold (const insert)

Example usage

compareSwap a b = if a > b then (a,b) else (b,a)
insert y xs     = let (y',xs') = mapAccumL compareSwap y xs in xs' :< y'
insertionSort   = vfold (const insert)

Builds a triangular structure of compare and swaps to sort a row.

>>> insertionSort (7 :> 3 :> 9 :> 1 :> Nil)
1 :> 3 :> 7 :> 9 :> Nil

The circuit layout of insertionSort, build using vfold, is:

maximum :: Ord a => Vec (n + 1) a -> a

The largest element of a non-empty vector

minimum :: Ord a => Vec (n + 1) a -> a

The least element of a non-empty vector

smap :: forall k a b. KnownNat k => (forall l. SNat l -> a -> b) -> Vec k a -> Vec k b

Apply a function to every element of a vector and the element's position (as an SNat value) in the vector.

>>> let rotateMatrix = smap (flip rotateRightS)
>>> let xss = (1:>2:>3:>Nil):>(1:>2:>3:>Nil):>(1:>2:>3:>Nil):>Nil
>>> xss
(1 :> 2 :> 3 :> Nil) :> (1 :> 2 :> 3 :> Nil) :> (1 :> 2 :> 3 :> Nil) :> Nil
>>> rotateMatrix xss
(1 :> 2 :> 3 :> Nil) :> (3 :> 1 :> 2 :> Nil) :> (2 :> 3 :> 1 :> Nil) :> Nil

Template Haskell

class Lift (t :: TYPE r) where

A Lift instance can have any of its values turned into a Template Haskell expression. This is needed when a value used within a Template Haskell quotation is bound outside the Oxford brackets ([| ... |] or [|| ... ||]) but not at the top level. As an example:

add1 :: Int -> Q (TExp Int)
add1 x = [|| x + 1 ||]

Template Haskell has no way of knowing what value x will take on at splice-time, so it requires the type of x to be an instance of Lift.

A Lift instance must satisfy $(lift x) ≡ x and $$(liftTyped x) ≡ x for all x, where $(...) and $$(...) are Template Haskell splices. It is additionally expected that lift x ≡ unTypeQ (liftTyped x).

Lift instances can be derived automatically by use of the -XDeriveLift GHC language extension:

{-# LANGUAGE DeriveLift #-}
module Foo where

import Language.Haskell.TH.Syntax

data Bar a = Bar1 a (Bar a) | Bar2 String
  deriving Lift

Levity-polymorphic since template-haskell-2.16.0.0.

Haskell Prelude

Clash.Explicit.Prelude re-exports most of the Haskell Prelude with the exception of those functions that the Clash API defines to work on Vec from Clash.Sized.Vector instead of on lists as the Haskell Prelude does. In addition, for the odd and even functions a type class called Parity is available at Clash.Class.Parity.
