Nuvacore CPU Performance Modeling Lead at Nuvacore owning the cycle-accurate CPU performance simulator and driving microarchitectural exploration. Lead model-to-RTL correlation and mentor performance engineers.
Responsibilities
- Design, develop and own Nuvacore’s cycle-accurate CPU performance simulator — its architecture, fidelity, and long-term roadmap — as the authoritative reference model for the design team.
- Lead microarchitectural exploration across all major CPU domains: frontend (fetch, decode, branch prediction), out-of-order engine (rename, dispatch, execution), and memory subsystem (caches, prefetchers, TLBs, coherence).
- Drive model-to-RTL correlation through all execution phases; own debug and resolution of performance miscorrelation between the performance model, RTL simulation, and post-silicon results.
- Collaborate closely with design, verification, compiler, and system software teams to align architecture decisions with implementation constraints and software stack realities.
- Mentor engineers across the performance team; provide technical leadership on modeling methodology, simulation infrastructure, and analysis tooling.
- Contribute to IP development through patents and, where applicable, external publication
