Reset Debug Playbook: Reports & Metrics

Reports and metrics

Reports & Metrics for Reset Debug Playbook focuses on reset-related failure reproduction time, first-pass root-cause hit rate. The goal is to convert issue observations into mechanism-backed closure decisions.

Reports must explain risk movement in reset-related failure reproduction time, first-pass root-cause hit rate, not just issue counts. A report is complete only when ownership and closure action are explicit.

Metric focus: reset-related failure reproduction time, first-pass root-cause hit rate

• Track reset-related failure reproduction time, first-pass root-cause hit rate by block, mode, and severity.

• Separate structural warnings from behavior-proven hazards.

• Show waiver age and owner SLA alongside raw counts.

• Store evidence links with each closure claim.

CDC/RDC deep dive

Reset release ordering is a first-order reliability contract.

Concept diagram

RESET RELEASE FLOW

assert global -> clocks stable -> sync release per domain -> first transaction

Metric graph

BOOT STABILITY

passes per 1k boots: 920 -> 980 -> 999

Reports and artifacts

• reset dependency matrix

• RDC warning classes

• boot stress logs

• waiver aging

Mini case study

Domain B released before producer A was valid, causing rare startup deadlock.

Debug branches

• Correlate reset and clock timelines

• verify async assert/sync release

• exercise skewed release tests

Senior review question

Ask: what evidence proves this risk is closed for silicon, not just tool-clean?

Key takeaways

• State crossing class, assumptions, and owner with every issue.

• Run structural and dynamic regressions after each fix.

Common pitfalls

• Treating all warnings as equivalent risk.

• Waiving issues without containment evidence.

• Skipping reset and reconvergence stress after CDC fixes.
