PROFILE
Artur Bieniek
Worked on the antmicro/verilator repository over four months, delivering enhancements and fixes to Verilog simulation and property verification workflows. Focused on improving timing fidelity, assertion framework robustness, and simulation determinism, the work included implementing rise/fall delay support, refining $finish semantics, and expanding property expression capabilities such as if/else and s_until constructs. Addressed correctness gaps by fixing event handling, unsized literal evaluation, and cross-platform build reliability. Leveraged C++, Verilog, and Python to optimize core algorithms, enforce standards compliance, and automate testing. These contributions strengthened simulation accuracy, reduced regression risk, and improved maintainability for users and downstream verification flows.
