Job Decription:

We are looking for a skilled STA Methodology Engineer to join the team working on and using the Statistical Timing Estimation Platform (STEP) — internal gateway to timing data for silicon projection and correlation. You will drive PVT-aware Fmax/Vmin estimation and be actively involved in post-silicon correlation and pre-silicon design closure across advanced technology nodes, collaborating with design, PnR, process technology, and silicon validation teams.

WHAT YOU'LL DO
- Drive STA methodology development for statistical timing estimation infrastructure: timing closure flows, PVT scaling model integration, and silicon frequency projection.
- Develop and validate PVT (Process, Voltage, Temperature) scaling models for logic cells, RAMs, FCM, and wire delay — leveraging Process Lookup Tables (PLUTs) for characterization across EOC/aging conditions.
- Analyze system-level performance metrics (Fmax, Vmin, MPE, MPW) and debug path-level timing reports — critical paths, cell/wire margins, crosstalk, and part-to-part sensitivity.




- Correlate pre-silicon STA results with post-silicon measurements to build and refine silicon projection models.
- Integrate layout-driven timing effects into STEP flows: IR-drop, SPEF scaling, EM/IR/Noise reliability impacts, and aging derates (EOC_AGING).
- Validate quality of timing estimation data and contribute to SPICE-level verification of timing models.

REQUIRED QUALIFICATIONS
- 5–7 years of hands-on STA experience, preferably in advanced node (7nm, 5nm, 3nm) ASIC or GPU design.
- Deep understanding of system-level performance metrics: Fmax, Min Period (MPE), Min Pulse Width (MPW), setup/hold closure at signoff corners.
- Solid path-level timing analysis skills:

◦ Reading and debugging STA signoff reports (PrimeTime or equivalent)

◦ Cell delay, wire delay, clock path contributions

◦ Cell/wire margin analysis, derating (OCV/AOCV/POCV), jitter (DCD, PLL uncertainty), and part-to-part variation sensitivity
