Features

  • Implement read-write memory accessors for SyncReadMem (backport #3190) (by @mergify[bot] in #3214)
    SyncReadMem.readWrite(address, writeData, enabled, isWrite) explicitly generates a read-write port that supports both read and write access to the memory.
  • Added more Connectable customization functions (backport #3227) (by @mergify[bot] in #3231)
    • Added .unsafe, a useful function on Connectable when users want a connection to "try its best but don't error".
    • Added .squeezeAllAs, a useful function on Connectable when users want a connection to always squeeze, as well as upcast if desired.
    • Added .as, a useful function on Connectable when users to upcast the Scala type.
    • Connectable's now register erroneous connections (e.g. out of scope, unwritable sinks) to throw at end of elaboration

  • Add Chisel Scala CLI template and automation (backport #3186) (by @mergify[bot] in #3194)
    Add a new Chisel template for using Chisel with Scala CLI, and adds some automation for uploading versions of this template on tagged releases (or workflow dispatch).
  • Add Data.findFirstTypeMismatch for better type checking (backport #3201) (by @mergify[bot] in #3205)
  • Read previousVersions for bincompat checking from a file (backport #3202) (by @mergify[bot] in #3208)
    We can now simply append versions as they are released to project/previous-versions.txt on relevant release branches. build.sbt also now contains instructions are how to waive binary compatibility breakages.
