During April 2025, Sam Herbst enhanced Verilog parsing in the xlsynth/bedrock-rtl repository, focusing on both speed and build stability. He optimized the load_module function in Rust to filter input sources, ensuring only top-level, package, and multi-definition files were parsed, which reduced unnecessary processing. Sam also updated build tooling by configuring the slang parser to run in single-threaded mode and upgrading TopStitch, addressing thread contention issues in parallel Bazel builds. His work in build system configuration, code optimization, and SystemVerilog parsing improved parsing times and reliability, supporting faster development cycles for large RTL codebases without introducing new bugs.
Month 2025-04 — Key Verilog parsing improvements in xlsynth/bedrock-rtl: speed and stability enhancements that support faster iteration on RTL code and more reliable builds. Implemented input-source filtering in load_module to parse only top-level, package, and multi-definition sources, and updated build/tooling: TopStitch 0.57.0 and single-threaded slang parser to reduce thread contention in parallel Bazel builds and improve handling of Verilog sources.
