Inputs and outputs contract

Inputs & Outputs for Top-Level Closure Dashboard focuses on open critical signoff items, closure burn-down trend. 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

A closure dashboard unifies timing, power, DRC/LVS, CDC/RDC, and verification readiness into a decision-grade tapeout view.
