Interview Discussion – Sign-off Ownership

• "Can you walk us through a time when you owned sign-off readiness under tight schedule constraints?"
  My Talking Points

  • Situation: Late-stage ASIC approaching tape-out with unresolved DRC and manufacturability risks.
  • Task: Own end-to-end sign-off readiness without impacting schedule.
  • Action: Identified systematic violations, worked directly with layout and foundry teams, and prioritized fixes based on manufacturing risk.
  • Result: Achieved first-time-right tape-out with no critical sign-off issues.
• "How do you decide whether a violation requires a local fix versus a systematic layout or rule-level change?"
  My Talking Points

  • Look for spatial repetition and pattern dependency.
  • Evaluate impact on manufacturability and OPC sensitivity.
  • Prefer systematic fixes when violations indicate process interaction.
  • Balance risk vs. schedule when deciding scope of change.
• "What trade-offs do you consider between verification closure and manufacturing robustness?"
  My Talking Points

  • Short-term closure vs. long-term yield and stability.
  • Foundry guidance and silicon history.
  • Risk of re-spin outweighs small schedule gain.
