Tapeout Readiness Review: Inputs & Outputs

Inputs & Outputs for Tapeout Readiness Review.

Inputs and outputs contract

Inputs & Outputs 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.

Treat these as a signed integration contract. Ambiguity here causes multi-team debug loops where everyone is right inside their own assumptions.

INPUTS
  - baseline manifest (versions + hashes)
  - interface/budget contract revision
  - mode assumptions (functional/test/low-power)
  - owner accountability map

OUTPUTS
  - measurable closure deltas
  - owner-approved fix proposal
  - regression evidence package
  - risk/waiver disposition

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.
