Worked on the antmicro/verilator repository to enhance optimization guidance within the Verilator toolchain, focusing on improving the UNOPTFLAT warning for flat-structured designs. Developed and integrated a new suggestion, “isolate_assignments,” into the warning message, providing users with actionable steps to optimize unoptimized flat structures. This targeted feature, implemented in C++, aimed to align tool output with practical optimization workflows and improve user experience for developers working on verification and synthesis. The work demonstrated skills in code generation, compiler development, and static analysis, with careful attention to traceability and review by linking the change to a relevant issue for transparency.
