PROFILE
Aleksander Kiryk
During October 2025, Arkadiusz Kiryk focused on stabilizing random number generation in the antmicro/verilator repository, addressing a subtle but impactful bug affecting multi-process workflows. He implemented per-process random state management by introducing new C++ methods in VlProcess and updating both verilated.cpp and verilated_types.h, ensuring that each process maintained its own RNG state. By integrating these changes with SystemVerilog through verilated_std.sv, Arkadiusz prevented cross-process interference and improved test determinism. His work, rooted in C++, SystemVerilog, and software testing, demonstrated careful attention to isolating state and maintaining code clarity, resulting in more reliable and maintainable simulation infrastructure.

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.
