Tapeout Readiness Review: Review Checklist

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.

OWNERSHIP MAP — Tapeout Readiness Review

artifact             owner
-----------------    -----------------
primary owner     program director

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.
