Top-Level Closure Dashboard: Worked Example

Worked example

Worked Example 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.

A review detects open critical signoff items, closure burn-down trend. Strong analysis starts by freezing baseline and proving where the first boundary failed in Top-Level Closure Dashboard.

Closure dashboard view

CLOSURE DASHBOARD

timing:   open/closed
power:    open/closed
phys:     DRC/LVS status
CDC/RDC:  waiver state
verification: signoff status

1. Capture failing artifact and manifest tags.

2. Map failure to one owner boundary.

3. Verify mechanism using one reduced repro.

4. Compare against closure dashboard, risk burndown chart, owner status report.

5. Select one reversible fix and define full regression upfront.

Always verify collateral, regression suite, and owner signoff.

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.
