RDC Methodology: Review Checklist

Review Checklist for RDC Methodology.

Review checklist

Review Checklist for RDC Methodology focuses on reset-domain hazard coverage, unresolved RDC severity count, closure quality. 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: RDC lead, methodology owner, verification lead.

OWNERSHIP MAP — RDC Methodology

artifact                  owner
----------------------    -------------------------
design intent           RDC lead
verification evidence   methodology owner
signoff decision        verification lead

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

RDC methodology treats reset behavior as a first-class asynchronous interface requiring intent capture, structural checks, and targeted dynamic proof.

Metric: reset-domain hazard coverage, unresolved RDC severity count, closure quality
