1.4.7 Jan 30th 2022

Fixed:

  • Clash now shows days in time strings for compile runs which take longer than a day #1989.
  • Types defined in the package head are no longer qualified in the package body when rendering VHDL #1996.
  • asyncRam with different read and write clocks no longer produce the wrong results in Haskell simulation. #2031
  • Clash.Explicit.RAM.asyncRam# Haskell simulation incorrectly treated an undefined write enable as asserted. It now causes an undefined value to be written instead. This problem did not propagate to the other asyncRam functions, where the same condition would simultaneously lead to an undefined write address, which would be handled correctly. This problem also only affects Haskell simulation, not the generated HDL. #2031
  • Clash.Explicit.BlockRam.blockRam# and Clash.Explicit.BlockRam.File.blockRamFile# Haskell simulation incorrectly treated an undefined write enable as asserted. It now causes an undefined value to be written instead. This problem did not propagate to the other blockRam functions, where the same condition would simultaneously lead to an undefined write address, which would be handled correctly. This problem also only affects Haskell simulation, not the generated HDL.(#2054)

Internal changes:

  • Removed instances of Hashable Term and Hashable Type #1986
  • Added structural equality on Term (Clash.Core.Subst.eqTerm) and Type (Clash.Core.Subst.eqType)

Internal fixes:

  • Enable used to be a Bool in the Blackbox DSL, so we could use boolToBit. However it now has its own type in the DSL (Enable domainName), so we've added a new conversion function in order to convert it to a Bool.
