Features

  • Add DeletedPath for targets that no longer exist. (backport #3937) (by @mergify[bot] in #3938)
    Sometimes a generator wants to emit a Path that targets some Data, but that Data isn't always produced by the generator. The DeletedPath can be used to represent the presence of a Path, but the absence of a Data in this case.
  • Add requireIsAnnotatable for better errors when annotating literals (backport #3968) (by @mergify[bot] in #3971)
    This gives much better error messages when accidentally dontTouching a literal

Performance

  • Optimize BitPat factory from UInt literals (backport #3988) (by @mergify[bot] in #3989)
    Speeds up conversion of UInt literals to BitPat by ~9x in practice, ~70x for large UInts.
  • Optimize truth table merge (backport #3993) (by @mergify[bot] in #3995)

Fixes

  • toBigInt should round identically for Double and BigDecimal (backport #3921) (by @mergify[bot] in #3927)
  • Fix Data.findFirstTypeMismatch to check all elements of Bundles (backport #3928) (by @mergify[bot] in #3930)
    Fixes DataMirror.checkTypeEquivalence to actually check all fields of Bundles and Records. This may expose latent bugs in user code.
  • Support literals in DataView (backport #3964) (by @mergify[bot] in #3966)
    View of literals will now themselves be literals. This also fixes an internal bug related to views of literals.
  • Fix === for abstract Reset types (backport #3979) (by @mergify[bot] in #3982)
    Previously, the function would infinitely recurse resulting in a stack overflow.
  • Provide require message for negative widths (backport #4008) (by @mergify[bot] in #4010)
    Fixes #4007

Documentation

  • Rename Scala CLI template to example (backport #3917) (by @mergify[bot] in #3920)
    Existing links to https://github.com/chipsalliance/chisel/releases/latest/download/chisel-template.scala should instead use https://github.com/chipsalliance/chisel/releases/latest/download/chisel-example.scala
  • [website] Bump Docusaurus to 3.1.1 and fix broken anchors (backport #3948) (by @mergify[bot] in #3949)
