Worked on simulation performance enhancements for the YosysHQ/yosys repository, focusing on optimizing the simulation path in C++. Introduced early-return checks in simulation mode and implemented caching of signal mappings to accelerate state retrieval and signal registration. Applied data structures and software optimization techniques to improve simulation throughput and responsiveness, supporting faster verification cycles and scalability for large designs. The work involved performance profiling, short-circuit evaluation, and incremental refactoring, with clear documentation and traceable commits. These targeted changes addressed core simulation bottlenecks and established a foundation for future improvements, aligning with the project’s performance objectives and release readiness requirements.
