Worked on enhancing the Setundef pass in the YosysHQ/yosys repository, focusing on precision-aware rewriting and expanded cross-mode testing. Leveraged C++ and Verilog to ensure that only user-selected cells, wires, and processes were affected, aligning rewrite behavior with explicit selections. Migrated tests to Verilog format for improved compatibility with Yosys test flows and refined the CI infrastructure to support reliable, repeatable runs. Incorporated feedback by updating process handling and mode-specific logic, improving maintainability and reducing regression risk. Emphasized comprehensive test coverage and clear documentation, demonstrating depth in algorithm design, code refactoring, and digital circuit synthesis within a collaborative workflow.

Mar 1, 2026March 2026 delivered a targeted refinement of the Setundef pass in Yosys, introducing precision-aware rewriting and expanded cross-mode testing. By aligning rewrite behavior with user selections and migrating tests to Verilog-compatible formats, the changes improve design safety, CI reliability, and overall maintainability. The work reduces risk of unintended initializations across -zero, -undriven, and -init modes while expanding test coverage and aligning with code-review feedback.
