PROFILE
Marco Bartoli
Worked on the antmicro/verilator repository to enhance simulation reliability and macOS compatibility. Delivered a macOS-specific AddressSanitizer memory limit configuration by leveraging system programming and memory management techniques in C++, aligning Verilator’s debugging tools with macOS expectations. Addressed simulation correctness by fixing Verilog interface properties, parameter handling, and execution flow in nested fork blocks, using test-driven development and Python scripting to validate changes and prevent regressions. These contributions improved cross-platform stability, reduced false positives in CI, and ensured robust simulation behavior, reflecting a focus on platform-specific optimization and rigorous validation across both hardware description and system-level code.
