Staff Engineer CPU DV
SiFiveJob Title
Staff Engineer, CPU DV
Role Summary
Lead design verification for high-performance CPU core microarchitecture. Drive verification strategy, architecture validation, and closure across simulation and emulation platforms to ensure functional correctness and silicon-quality delivery.
Experience Level
Senior — 6+ years of professional experience in CPU design verification or equivalent verification roles.
Responsibilities
Primary responsibilities include:
- Own end-to-end verification of CPU core components: Fetch, Decode, Execute, Memory, Pipeline, Cache, MMU.
- Develop verification plans from architecture specifications and ensure coverage closure.
- Validate microarchitectural features such as out-of-order execution, branch prediction, cache coherency, and virtual memory/paging.
- Lead verification execution using SystemVerilog and UVM.
- Implement testbenches, constrained-random tests, scoreboards, checkers, and coverage models (functional and code).
- Run regressions and debug complex failures across simulation and emulation platforms.
- Collaborate with Architecture and Design teams to validate corner cases, exceptions, interrupts, and perform ISA-level validation and compliance testing.
Requirements
Core qualifications and skills required:
Must-have- 6+ years of experience in CPU/core microarchitecture verification.
- Proven experience with SystemVerilog and UVM-based verification environments.
- Experience creating testbenches, constrained-random tests, scoreboards/checkers, and coverage-driven verification.
- Strong debugging skills across simulation and emulation platforms and driving regression suites to closure.
- Familiarity with CPU microarchitectural concepts: out-of-order execution, branch prediction, cache coherency, MMU, and virtual memory.
- Experience performing ISA-level validation and working with ISA behaviors (examples: RISC-V, ARM, or x86).
- Hands-on experience with emulation platforms or hardware-assisted verification flows.
- Prior experience validating high-performance processors at silicon bring-up.
Education Requirements
Not specified.
