Chip-level RDC Closure: Review Checklist

Review Checklist for Chip-level RDC Closure.

Review checklist

Review Checklist for Chip-level RDC Closure focuses on top-level RDC open count, subsystem handoff completeness, integration churn. The goal is to convert issue observations into mechanism-backed closure decisions.

  • Crossing and reset intent are explicitly classified.

  • Protocol assumptions are documented and checked.

  • Critical issues have owners and dates.

  • Waivers include mechanism, containment, and expiry.

  • Regression matrix includes stress and milestone modes.

  • Owners signed: SoC lead, RDC lead, IP owners.

OWNERSHIP MAP — Chip-level RDC Closure

artifact                  owner
----------------------    -------------------------
design intent           SoC lead
verification evidence   RDC lead
signoff decision        IP owners

Every open CDC/RDC issue needs one accountable owner before waiver or fix.

CDC/RDC deep dive

RDC closure must connect IP assumptions to SoC reality.

Reports and artifacts

  • top-level RDC opens

  • reset simulation coverage

  • chip integration blockers

  • waiver backlog

Mini case study

Each IP was locally clean, but top-level sequencing violation created cross-subsystem boot intermittency.

Debug branches

  • Audit subsystem assumptions

  • stress chip-level reset scenarios

  • close ownership gaps

Senior review question

Ask: what evidence proves this risk is closed for silicon, not just tool-clean?

Key takeaways

  • State crossing class, assumptions, and owner with every issue.

  • Run structural and dynamic regressions after each fix.

Common pitfalls

  • Treating all warnings as equivalent risk.

  • Waiving issues without containment evidence.

  • Skipping reset and reconvergence stress after CDC fixes.

Principal CDC/RDC review addendum

Chip-level RDC closure depends on clean reset intent handoff from IPs and alignment between subsystem sequencing assumptions.

Metric: top-level RDC open count, subsystem handoff completeness, integration churn
