Snohomish
We are hiring Static Timing Analysis engineers to strengthen the timing signoff team supporting a leading SoC manufacturer on advanced-node designs. In this role you will own timing constraints, drive block- and full-chip timing closure across all modes and corners, and collaborate closely with the physical design, synthesis, and DFT teams to deliver clean, silicon-ready timing signoff.
The ideal candidate has strong fundamentals in static timing analysis, hands-on experience with industry signoff tools, and a proven track record of closing timing on complex, high-frequency designs at advanced FinFET technology nodes.
Key Responsibilities
• Timing constraints (SDC): Develop, review, validate, and maintain timing constraints — clock definitions, generated clocks, I/O delays, false paths, multicycle paths, and clock-domain-crossing (CDC) exceptions — and ensure constraint consistency and quality.
• Timing signoff: Perform block-level and full-chip static timing analysis and signoff using Synopsys PrimeTime / PrimeTime SI (and/or Cadence Tempus) across a full multi-mode multi-corner (MMMC) setup.
• Timing closure: Analyze and close setup, hold, recovery/removal, and transition/capacitance violations; generate and implement timing ECOs and coordinate fixes with the place-and-route team.
• Signal integrity: Run crosstalk delay and noise (SI) analysis, identify and resolve SI-induced violations, and correlate with extraction and physical data.
• Parasitic correlation: Set up and validate RC parasitic extraction and SPEF (StarRC / Quantus QRC), manage RC corners, and ensure extraction-vs-signoff correlation.
• Variation-aware analysis: Apply OCV / AOCV / POCV (SOCV) derating methodologies and drive accurate margin-aware signoff.
• Hierarchical timing: Build and validate timing abstracts / interface models (ETM / ILM), perform interface timing budgeting, and support top-level integration for hierarchical designs.
• Low-power timing: Handle UPF-based multi-voltage / multi-power-domain designs, including level shifters, isolation cells, and power-aware timing checks.
• Flow & automation: Automate and enhance timing analysis and ECO flows using TCL / Python / Perl; improve turnaround time and reporting.
• Collaboration & signoff quality: Work with synthesis, P&R, CTS, DFT, and IR/EM teams; document methodology, present timing reviews, and provide silicon-ready signoff sign-off criteria and reports.
