Reports and metrics

Reports & Metrics for Waiver & Risk Governance focuses on waiver aging, post-silicon waiver escape rate. The goal is to map symptoms to boundary contracts, owner actions, and regression-proof closure.

The job of a report is to convert waiver aging, post-silicon waiver escape rate into a closure decision. One summary number is never enough without baseline, owner, and boundary context.

Debug the high-severity tail first; averages hide escape risk.

• Track waiver aging, post-silicon waiver escape rate by domain and owner boundary.

• Store baseline manifest beside every metric snapshot.

• Report both immediate fix result and full regression result.

• Explicitly call out residual risk and ownership.

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.
