Tapeout Readiness Review: Step-by-Step Walkthrough

Step-by-step analysis walkthrough

Use when you own Tapeout Readiness Review in a top-level integration review.

1. Open latest integration baseline and manifest.

2. Inspect failing metric by domain.

3. Trace first failing contract boundary.

4. Collect artifacts and assign single-thread owner.

5. Define minimal proof experiment.

6. Apply smallest reversible fix.

7. Run focused check then full regression.

8. Update dashboard and governance log.

9. Decide: close, waive with expiry, or escalate.

10. Publish final review memo.

Artifacts to collect

• TRR deck, closure checklist, final release package

• baseline manifest

• owner matrix

• regression summary

• risk memo

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.

Metric: tapeout checklist pass rate, late blocker count
