SOC Timing Analysis (STA) Engineer ,HBM

About This Role

• Responsibilities will include, but are not limited to: Own end-to-end chip-level static timing analysis and sign-off, covering all timing checks including setup, hold, recovery, removal, and data-to-data across all process corners, operating modes, and voltage and temperature conditions.
• Develop, maintain, and validate comprehensive Synopsys Design Constraints (SDC) for all clock domains, reset trees, high-bandwidth memory (HBM) physical interfaces, Joint Test Action Group (JTAG), memory built-in self-test (MBIST), design for test (DFT), and configuration logic, ensuring sign-off quality and reuse across design generations.
• Drive timing closure at block, subsystem, and full-chip levels through critical path analysis, timing engineering change orders (ECOs), and close collaboration with physical design teams on placement, clock tree synthesis (CTS), and routing to meet timing targets.
• Perform multi-mode, multi-corner (MMMC) timing analysis including setup and hold closure, clock domain crossing (CDC) timing, and application of on-chip variation derates (OCV, AOCV, POCV) appropriate for advanced technology nodes.
• Lead signal integrity and crosstalk analysis, identify noise-induced timing violations, and work with physical design teams to implement mitigation strategies, while conducting DFT timing analysis including scan chain timing, automatic test pattern generation (ATPG) mode constraints, MBIST timing closure, and JTAG interface timing.
• Partner with RTL and architecture teams to provide early static timing analysis feedback on micro-architectural decisions, clock architecture, timing budgets, and power and area tradeoffs, and develop and maintain automation scripts and flows in Python and Tcl for constraint generation, timing report extraction, waiver management, quality of results dashboards, regression tracking, and sign-off readiness reporting.
• Perform post-silicon timing correlation by analyzing silicon measurement data against pre-silicon predictions, identifying systematic discrepancies, feeding learnings back into timing models, tool settings, and methodology updates, and engaging directly with electronic design automation tool vendors to evaluate new features, resolve tool issues, and drive methodology enhancements.
• Define and drive organization-wide static timing analysis methodology, sign-off standards, and timing closure best practices; lead readiness reviews and tape-out sign-off gates; mentor and grow junior engineers; contribute to design documentation, timing sign-off reports, constraint specifications, and block-level timing budgets; and collaborate cross-functionally with Physical Design, RTL Design, Verification, DFT, Product Engineering, and Test teams to ensure timing requirements are met through all phases of the design cycle.
