About the role
- when they're fast and accurate, the whole program moves faster.
Responsibilities
- Design, build, and maintain the software simulators and models of our AI accelerator - functional / ISA simulators, cycle-approximate performance models, and the C++/Python infrastructure around them
- Build the pre-silicon development surface for the software teams: golden reference models, co-simulation, trace generation, and validation harnesses the compiler and runtime develop against daily
- Correlate models against RTL, emulation, and first silicon as they arrive, and drive the deltas back into the model to keep it trustworthy
- Use and develop AI-assisted tool flows to accelerate model development and validation
- 5+ years building simulators, emulators, virtual platforms, ISS, or large-scale systems/infrastructure software
- Real simulation/modeling judgment: functional vs. cycle-approximate trade-offs, validating against a reference, and optimizing the simulator's own performance
Requirements
