Job Summary
We are seeking a highly skilled Senior Static Timing Analysis (STA) Engineer to join our ASIC implementation team. The ideal candidate will have extensive experience in timing analysis, timing closure, and signoff for complex SoC designs at advanced technology nodes. The engineer will work closely with RTL, Physical Design, DFT, and CAD teams to ensure successful timing convergence and tape-out.
Key Responsibilities
Own full-chip and block-level timing closure from synthesis through signoff.
Perform static timing analysis across multiple operating modes and PVT corners.
Develop, review, and maintain timing constraints (SDC).
Analyze and resolve setup, hold, recovery, removal, clock gating, pulse width, and timing exception violations.
Perform SI-aware timing analysis and crosstalk delay/noise debugging.
Collaborate with Physical Design teams to optimize placement, CTS, routing, and ECO implementation for timing closure.
Generate and validate timing ECOs while ensuring minimal impact on power, area, and functionality.
Validate timing exceptions including false paths, multicycle paths, asynchronous paths, and generated clocks.
Perform timing signoff using industry-standard EDA tools.
Support timing correlation between implementation and signoff environments.
Develop automation scripts to improve timing analysis and reporting.
Participate in design reviews and provide technical guidance on timing-related issues.
Mentor junior engineers and contribute to methodology improvements.
