Tool Updates

  • Updated nix-eda to 0814aa6: more orthodox approach to managing dependencies by overlaying them on top of nixpkgs, which fixes an occasional "repeated allocation" issue and helps make override behavior more consistent.
    • Yosys and first-party plugins updated to 0.46
  • OpenLane itself no longer included in devShells.*.dev, devShells.*.docs
    • These shells are intended to be actual dev shells, i.e. used to develop OpenLane, and needing OpenLane to pass tests to run these shells makes no sense.
