0.11.2

• New features:
  • Add riseEvery: Give a pulse every n clock cycles. (Thanks to @thoughtpolice)
  • Add oscillate: Oscillate a Bool with a given half-period of cycles. (Thanks to @thoughtpolice)
• Fixes bugs:
  • Eagerness bug in regEn #104 (Thanks to @cbiffle)

v0.11.1

• Changes:
  • Bundle instance for () behaves like a product-type instance #96
• Fixes bugs:
  • Ensure that fold gets correctly type-applied in Vec.== #202

v0.11

• New features:
  • CLaSH.XException: a module defining an exception representing uninitialised values. Additionally adds the ShowX class which has methods that prints values as "X" where they would normally raise an XException exception.
  • Add BNat (and supporting functions) to CLaSH.Promoted.Nat: base-2 encoded natural numbers.
  • Add divSNat and logBaseSNat to CLaSH.Promoted.Nat: division and logarithm for singleton natural numbers.
  • Add predUNat and subUNat to CLaSH.Promoted.Nat: predecessor and subtraction for unary-encoded natural numbers.
  • Add dtfold to CLaSH.Sized.Vector: a dependently-typed tree-fold over Vec.
  • Add the perfect-depth binary trees module CLaSH.Sized.RTree
  • Synthesisable definitions of countLeadingZeros and countTrailingZeros for: BitVector, Signed, Unsigned, and Fixed
  • Add the (:::) type alias in CLaSH.NamedTypes which allows you to annotate types with documentation
• Changes:
  • asyncRam, blockRam, blockRamFile have a Maybe (addr,a) as write input instead of three separate Bool, addr, and a inputs.
  • asyncFIFOSynchronizer has a Maybe a as write-request instead of a separate Bool and a input
  • bundle' and unbundle' are removed; bundle now has type Unbundled' clk a -> Signal' clk a, unbundle now has type Signal' clk a -> Unbundled' clk a
  • subSNat now has the type SNat (a+b) -> SNat b -> SNat a (where it used to be SNat a -> SNat b -> SNat (a-b))
  • Renamed multUNat to mulUNat to be in sync with mulSNat and mulBNat.
  • The function argument of vfold in CLaSH.Sized.Vector is now (forall l . SNat l -> a -> Vec l b -> Vec (l + 1) b) (where it used to be (forall l . a -> Vec l b -> Vec (l + 1) b))
  • Cons constructor of Vec is no longer visible; (:>) and (:<) are now listed as constructors of Vec
  • Simulation speed improvements for numeric types

v0.10.11

• New features:
  • Add strict version of: sample, sampleN, fromList, and simulate
  • Make Signals <*> slightly stricter:
    • Feedback loops still work with this new implementation
    • No more space-leaks when used in combination with the strict version of sample, sampleN, and simulate
  • Add NFData instances for the numeric types
• Speed up arithmetic operations of Signed, Unsigned and BitVector
• Fixes bugs:
  • CLaSH compiler sees internals of numeric types in their Lift functions

v0.10.10

• Fixes bugs:
  • shrink functions for numeric types throw exceptions #153
  • CLaSH compiler sees internals of numeric types in their Show functions

v0.10.6

• Fixes bugs:
  • CLaSH.Prelude.DataFlow.parNDF is not lazy enough

v0.10.5

• New features:
  • Add readNew to CLaSH.Prelude.BlockRam: create a read-after-write blockRAM from a read-before-write blockRAM.
  • popCount functions for BitVector, Signed, and Unsigned are now synthesisable.
  • Add parNDF to CLaSH.Prelude.DataFlow: compose N dataflow circuits in parallel.
  • Add and instance Vec n a for LockStep in CLaSH.Prelude.DataFlow: have N dataflow circuits operate in lock-step.

v0.10.4

• New features:
  • Add pureDF to CLaSH.Prelude.DataFlow: lift combinational circuits to DataFlow circuits.
  • Add fifoDF to CLaSH.Prelude.DataFlow: a simple FIFO buffer adhering to the DataFlow protocol.
  • loopDF no longer uses the lockStep and stepLock automatically, and now includes a FIFO buffer on the feedback path.
  • Add loopDF_nobuf to CLaSH.Prelude.DataFlow: a version of loopDF with no FIFO buffer on the feedback path.
  • Add boolToBV to CLaSH.CLass.BitPack: convert Booleans to n-bit BitVectors.
  • ClockSource in CLaSH.Annotations.TopEntity can now have multiple clock inputs #33
• Bug fixes:
  • asyncRomFile reads file multiple times.

v0.10.3

• Disable CPR analysis (See clash-lang/clash-compiler@721fcfa):
  • GHC < 7.11: In all modules using -fcpr-off
  • GHC >= 7.11: In CLaSH.Signal.Internal and CLaSH.Prelude.RAM using -fno-cpr-anal

v0.10.2

• New features
  • ExtendingNum, BitPack, and Resize instance for Index
  • Add bv2i: convert BitVector n to Index (2^n)
