Description Staff Engineer, STA – Functional SDC Lead Function: ASIC Design / Physical Design – Signoff |
Location:
[Bangalore] | Reports to: [Manager] Role Summary Own the functional timing constraints (SDC) for advanced-node SoCs, from definition through signoff. You will lead the development, quality and ongoing maintenance of functional-mode constraints, so that STA, synthesis and PD work from complete and correct timing intent. You will work with Architecture, RTL, DFT, CDC/RDC, IP, Physical Design and the SoC Timing Lead.
Key Responsibilities
• Functional SDC ownership:
Develop and maintain top-level and block-level functional constraints. Cover clocks, generated clocks, clock groups, I/O delays, case analysis, and timing exceptions (false and multicycle paths).
• Constraint intent and review: Work with RTL, architecture and IP owners to capture and review clocking and timing intent. Drive constraint sign-off with these teams.
• Constraint quality: Run constraint checks (e.g., missing or conflicting constraints, unconstrained paths, exception validation) and CDC/RDC alignment. Keep functional constraints consistent between synthesis, PD and signoff.
• Mode and hierarchy management: Define functional modes and constraint hierarchy across blocks, subsystems and the full chip. Handle IP and hard-macro constraint integration, and block-to-top constraint propagation.
• Interface and IO constraints: Define timing constraints for high-speed and source-synchronous interfaces (e.g., DDR, PCIe, die-to-die) with IP and PHY teams.
• Debug and closure support: Debug constraint-related timing violations and exception issues, and support convergence with PD and the timing lead.
• Flow and automation: Develop scripts and flows for constraint generation, checking and regression. Maintain checklists and documentation.
• Leadership: Lead and mentor SDC engineers, track schedule and risk, and report status to program and management teams.
Qualifications
• BS/MS in Electrical Engineering or a related field.
• 8+ years in ASIC STA or constraint development, with multiple advanced-node tape-outs.
• Strong command of SDC, clocking architectures, and timing exceptions.
• Experience with hierarchical constraint management and block-to-top propagation.
• Familiarity with CDC/RDC concepts and constraint-checking tools.
• Tools: PrimeTime, Tempus, and constraint-quality tools (e.g., Conformal Constraint Designer, Spyglass or equivalent).
• Scripting in Tcl, Python or Perl.
• Preferred: High-speed interface constraints, multi-voltage (UPF) awareness, and experience leading constraint methodology.
