PROFILE
Rice Shelley
Shelley Rice contributed to the siliconcompiler/siliconcompiler repository by developing and enhancing automation and simulation workflows for FPGA and digital design verification. Over six months, Shelley implemented Python-based test automation using Cocotb, integrated Verilog and Tcl scripting for hardware simulation, and improved CI/CD reliability. Their work included building a Cocotb hardware test framework supporting Icarus Verilog and Verilator, adding flexible script execution within Vivado flows, and refining simulation workflows with timescale configuration and command file management. Shelley’s engineering addressed reproducibility, streamlined onboarding, and reduced debugging time, demonstrating depth in Python scripting, EDA tool integration, and robust test infrastructure development.

Mar 1, 2026March 2026 performance highlights for siliconcompiler/siliconcompiler: Delivered Verilog-style plusargs support via a new PlusArgs mixin for CocotbExecTask, enabling users to set, add, and retrieve simulation command-line arguments with per-step/index retrieval. Introduced API rename from add_plusargs to add_plusarg, and implemented associated tests and documentation updates. The work also included multiple review cycles and targeted fixes to improve code quality and maintainability. This enhancement increases configuration flexibility, improves reproducibility of simulation runs, and strengthens tooling for hardware/software co-design within the project.

Feb 1, 2026February 2026 (siliconcompiler/siliconcompiler) monthly summary: Implemented enhancements to the adder design simulation workflow for Icarus and Verilator to streamline verification, including timescale setup examples, simulator command files, and an update to make.py to include these steps in the Workflow. This deliverable improves reproducibility and reduces setup time for adder verification across simulators. No major bugs were reported this month. Overall impact: faster iteration cycles, better test coverage reliability, and easier onboarding for contributors. Technologies/skills demonstrated: Verilog/SystemVerilog simulators (Icarus Verilog, Verilator), timescale configuration, Python scripting (make.py), and workflow automation.
