CDC Review Gate: Review Checklist

Review Checklist for CDC Review Gate.

Review checklist

Review Checklist for CDC Review Gate focuses on gate pass rate, late-stage CDC churn, review defect leakage. 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: program lead, CDC owner, integration lead.

OWNERSHIP MAP — CDC Review Gate

artifact                  owner
----------------------    -------------------------
design intent           program lead
verification evidence   CDC owner
signoff decision        integration lead

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

CDC/RDC deep dive

Signoff is an evidence governance problem across teams.

closure trend

Mini case study

Pass rates improved while critical waivers aged out of policy; dashboard exposed hidden risk.

Debug branches

Separate quality from quantity metrics
enforce waiver expiry
run gate checklists consistently

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

Gate reviews align RTL, verification, and signoff evidence before integration milestones to avoid endgame metastability surprises.

Metric: gate pass rate, late-stage CDC churn, review defect leakage
