PROFILE
Jakub Wasilewski
Worked on the antmicro/verilator repository to deliver two targeted feature enhancements over a two-month period, focusing on simulation flexibility and test bench capability. Developed C++ and SystemC support for the sc_biguint pragma, enabling signal widths from 1 to 512 and allowing more scalable and accurate Verilog simulations. Additionally, enhanced Verilator’s std::randomize functionality to traverse complex expressions, including member and array selections, improving compatibility with other simulators and expanding randomization options for test benches. The work demonstrated depth in C++ development, Python scripting, and Verilog simulation, addressing specific needs in hardware modeling and automated verification workflows.

Nov 1, 2025November 2025: Delivered Verilator sc_biguint pragma support in the antmicro/verilator repository, enabling signal width specification from 1 to 512. This enhancement provides more flexible and scalable signal handling in simulations, reducing manual configuration and improving model accuracy and performance for wide signals. The change is captured in commit 0b8c3697403aefd7830cfc7292880c4448454710 with the message 'Add `sc_biguint` pragma (#6712)'.
