WebI worked on the verification of in-order and out-of-order RISCV cores. I developed test templates for the verification of LSU (load store unit) which includes verification of RVWMO (RISCV Weak memory model), Atomic extension (A), cache, cache coherence, store buffer and bus buffer modules. Meanwhile, I also developed a tool for RISCV ISA coverage.
