  • SystemVerilog source-map expansion and Verilator wrapper generation.
  • Docker-based Verilator compile path via SvPortSim.Compiler.compile/3.
  • Runtime operations for reset, tick, poke, peek, metadata, and shutdown.
  • Tests for wrapper generation, protocol framing, runtime error handling, and the generated RTL compile-and-run workflow.

Fixed

  • Elixir 1.20 / OTP 29 warning regressions in compile and test paths.
