Review checklist

Review Checklist for Tapeout Readiness Review focuses on tapeout checklist pass rate, late blocker count. The goal is to map symptoms to boundary contracts, owner actions, and regression-proof closure.

• Baseline manifest and revision are explicit.

• Boundary contracts for this topic are current and approved.

• Ownership map covers all open issues.

• Focused and full regression evidence both exist.

• Residual risks are either closed or bounded via waiver policy.

• Owners signed: program director, signoff lead, integration lead.

Signoff ownership

OWNERSHIP MAP — Tapeout Readiness Review

artifact             owner
-----------------    -----------------
primary owner     program director
co-owner          signoff lead
review owner      integration lead

No top-level issue should remain ownerless beyond one review cycle.

SoC deep dive

Signoff confidence depends on evidence quality and reproducibility discipline.

Reports and artifacts

• closure dashboard

• signoff manifest

• waiver aging report

• TRR checklist

Mini case study

A near-tapeout risk was caught when manifest mismatch invalidated an apparently green closure report.

Debug branches

• Validate manifest integrity

• Bound waiver risk

• Audit cross-domain owner approvals

Senior review question

Ask: what baseline, owner, and artifact prove this topic is truly closed?

Key takeaways

• State baseline manifest and owner with every closure metric.

• Run cross-domain regression after every top-level fix.

Common pitfalls

• Comparing results across different manifests.

• Unowned issues slipping through review cycles.

• Waiving risks without expiry and validation plan.

Principal SoC review addendum

Tapeout readiness is an executive review that validates technical closure, reproducibility, and contingency posture before irreversible handoff.
