careers@nuvacore.aiCPU Design Verification (Lead & IC Engineers)
Full-time · US / Canada / UK / India or Hybrid · IC + Tech Lead
Nuvacore is building ground-up high performance, low-power CPU for next-generation compute workloads. As engineers within the CPU team and as leads of CPU units verifying functionality and correctness (fetch, decode/rename, scalar execute, fp/vector execute, load/store, memory management/TLB, prefetching, debug/trace, system/IO, and multi-level cache subsystem), you will be responsible for all phases of pre-silicon verification.
THE ROLE
As a CPU Design Verification (DV) Engineer, you will participate in the following:
- Building testing environments which target every aspect of the CPU unit, core, or system. Your goal is to find every weakness and flaw in the design using proven verification techniques.
- Run verification simulations and debug the CPU using various EDA or inhouse waveform debug tools.
- Triage issues and write up detailed bug reports to assist the CPU design team in fixing design issues.
- Develop and write detailed test plans for the CPU units, core, or system.
- Develop DV methodologies and best practices for the team.
- Test and debug the performance of a CPU against the performance model.
- With a solid understanding of coverage, develop test and checks for the CPU
- Writing tests in ASM, C, C++, or other to test the CPU’s correctness according to the test plan
- Verification and testing of the gate level design of the CPU.
REQUIREMENTS — MUST HAVE
- BS or MS with 15+ (leads) and 7+ (ICs) years experience in CPU verification
- Experience with coding in Verilog, debugging, simulation, ideal experience in driving modern AI engines to assist in test plan development, verification and testing
- Understanding in architecture and design practices and the trade-offs in verifying CPU designs.
- Experience with RISC-V or ARM64 or x86 ISA
- Strong communication skills and aptitude in debugging and breaking things in CPUs
REQUIREMENTS — nice to HAVE
- Years of expertise in one or more of the following areas of CPU verification: instruction fetch, branch prediction; instruction decoding, scheduling and register renaming; out-of-order execution; integer and floating point execution; load/store execution; prefetching; cache and memory subsystems; translation and memory management; memory coherence and ordering; power and thermal management; and, clocking / reset design
- Strong background in low power microarchitecture and high-performance verification techniques, with a proven track record of verification and sign-off on multiple CPU programs. Ideally, you have seen multiple designs from concept to production.
- Experience in C, C++, System Verilog, scripting and other languages such as Perl or Python
