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, ensuring asynchronous memory reads and aligning naming conventions with Verilator standards. Using skills in build systems, Verilog, and C++, he addressed a type mismatch in FlashHelper, passing r_data as a pointer to prevent incorrect 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 simulation environments.
