PROFILE
Cai Weipeng
Cai Weipeng contributed to the OpenXiangShan-Nanhu/Nanhu-V5 repository by enhancing hardware testability and maintainability through Design for Test (DFT) logic and SRAM integration. Using SystemVerilog and Scala, Cai refactored the SRAM interface, updated XScore connections, and improved L2 MBIST controls, enabling faster hardware validation and clearer component interfaces. Cai also managed dependencies and fixed DFT-related bugs in submodules, ensuring consistent integration. In response to hardware updates, Cai removed obsolete MBIST logic, reducing dead code and aligning the codebase with new register-based SRAM. This work demonstrated depth in RTL design, embedded systems, and system integration practices.

1 Commits
May 1, 2025In May 2025, completed a focused code cleanup to align Nanhu-V5 with hardware changes by removing obsolete MBIST logic tied to the SRAM updated to registers. This reduces maintenance surface, eliminates dead code, and mitigates potential verification risk introduced by legacy MBIST paths. The work is tightly traceable to a single commit and prepares the codebase for future MBIST/verification optimizations.
