Description

About the Role
We are looking for a Design Verification Engineer to support gate-level simulation (GLS) and hardware emulation activities for our AI chip design and verification teams. In this role, you will help ensure silicon correctness by validating post-synthesis netlists, debugging timing and reset issues, and enabling large-scale emulation of SoC designs prior to tapeout. This is a hands-on role requiring close collaboration with RTL design, DFT, physical design, and firmware teams.

Key Responsibilities
- Set up, run, and debug gate-level simulations (GLS) for functional, timing (SDF back-annotated), and low-power verification across multiple design blocks and full-chip levels.
- Support hardware emulation platforms Siemens Veloce including design compilation, bring-up, debug, and regression management.
- Debug mismatches between RTL and gate-level simulation results, including X-propagation, timing violations, glitches, and clock/reset domain issues.
- Develop and maintain testbenches, scripts, and flows to automate GLS and emulation compile/run cycles.




- Collaborate with DFT engineers to validate scan, ATPG patterns, and BIST in gate-level and emulation environments.
- Work with physical design and STA teams to resolve SDF annotation, timing exceptions, and back-annotated simulation discrepancies.
- Bring up emulation models for pre-silicon software/firmware validation and performance profiling.
- Triage and root-cause simulation/emulation failures, track bugs, and drive issues to closure with cross-functional teams.
- Optimize simulation and emulation runtimes, capacity, and compile turnaround for large SoC designs
- Maintain documentation of GLS/emulation methodologies, flows, and known issues.
