Worked on the antmicro/verilator repository to enhance SystemVerilog simulation fidelity by implementing support for forced assignments on unpacked arrays and improving bit-range handling. Addressed reliability issues in mailbox functionality and assertion management, introducing targeted tests to validate packed structure handling and assertion randomization. Delivered fixes for clocking-block sample handling and iff guard behavior, accompanied by regression tests to ensure robust simulation under varied conditions. Leveraged C++, Python, and Verilog to drive these improvements, focusing on test-driven development and automation. The work reduced verification risk and expanded modeling capabilities for users working with complex hardware constructs in Verilator-based environments.
