PROFILE
Zihao Yu
Yuzihao contributed to the OpenXiangShan/difftest repository by enabling GSIM-based simulation and improving flash read safety. He integrated GSIM-compatible stubs and updated build scripts to support new C++ sources, allowing asynchronous memory reads and aligning naming conventions with Verilator standards. Using skills in Verilog, C++, and build systems, Yuzihao addressed a type mismatch in FlashHelper, ensuring correct pointer handling for flash reads. These changes reduced integration risk and accelerated validation cycles, resulting in more reliable test automation and smoother release processes. His work demonstrated a solid understanding of hardware interaction and low-level programming within a complex simulation environment.
