Worked on the antmicro/verilator repository to address random number generation stability in multi-process workflows. Focused on fixing a bug where global RNG state could be inadvertently affected by process-specific calls, the developer implemented per-process random state management by introducing new C++ methods and updating SystemVerilog integration. This approach ensured that each process maintained its own random state, preventing cross-process interference and improving test determinism. The solution involved changes to verilated.cpp, verilated_types.h, and verilated_std.sv, leveraging skills in C++, SystemVerilog, and software testing. All code was localized, reviewed, and prepared for mainline integration, directly resolving tracked issues.

Oct 1, 2025Month 2025-10 monthly summary focusing on key accomplishments, highlighting business value and technical achievements for antmicro/verilator. The primary deliverable this month was stabilizing RNG behavior in a multi-process Verilator workflow by implementing per-process random state management. This included adding new API methods and integrating them across C++ and SystemVerilog to ensure get_randstate retrieves the correct per-process state without disturbing global RNG stability.
