Aidan contributed to the conneroisu/sfhw-proj2 repository by developing and validating core components of a pipelined MIPS CPU, focusing on pipeline stage implementation, hazard detection, and testbench infrastructure. He engineered the EX_MEM and MEM_WB pipeline stages, ensuring correct data propagation and robust forwarding logic, while standardizing module naming for simulation compatibility. Using VHDL, Verilog, and MIPS Assembly, Aidan enhanced the pipeline’s reliability through comprehensive testbenches and simulation debugging. His work addressed structural and data hazards, improved waveform visualization, and introduced versioning, resulting in a more maintainable and verifiable hardware design with accelerated validation cycles and streamlined future development.
December 2024 — Delivered core MIPS validation harness, pipeline core enhancements, and robust visualization and versioning for sfhw-proj2, while advancing testbench maturity and tooling. Implemented critical bug fixes (TB naming, hazard cleanup, structural hazard resolutions) that improved reliability and reduced debugging time. This work increases verification coverage, stabilizes the pipeline path, and supports release readiness with clear software versions and hazard-aware NOPs, accelerating future feature work and hardware validation.

Monthly Summary for 2024-11 focused on pipeline maturation and validation in conneroisu/sfhw-proj2. Key features delivered include the EX_MEM pipeline stage initialization with foundational components for the EX-to-MEM data path, and the MEM_WB pipeline stage implementation (module, data-path mux, signal naming, and documentation) enabling correct data propagation through the final write-back stage. Added ForwardUnit testing and validation to ensure forwarding logic behaves under hazards, and standardized the RegisterFile naming with compatibility fixes for testbenches (RegisterFile.vhd renamed to register_file.vhd) plus debug support. Major bug fixes include stabilization of the MEM_WB data path (resolving overlap/edge-case issues and ensuring consistent carry-over behavior across cycles) and comprehensive TB updates to MEM_WB, culminating in a finished tb_MEM_WB that passes across test vectors. TB stability improvements extended to ForwardUnit tests as well. Overall impact: improved pipeline reliability and correctness across EX/MEM/MEM_WB, enabling more accurate CPU simulations and faster validation cycles. The updates reduce risk for future feature work and simplify maintenance with clearer naming and better-documented components. Technologies/skills demonstrated: HDL design (VHDL/Verilog), pipelined CPU datapath development, testbench creation and debugging (ForwardUnit and MEM_WB TBs), simulation hygiene, and a disciplined approach to naming conventions and documentation.
