CDC Tool Flow: Reports & Metrics

Reports and metrics

Reports & Metrics for CDC Tool Flow focuses on analysis runtime, violation classification completeness, delta noise between runs. The goal is to convert issue observations into mechanism-backed closure decisions.

Reports must explain risk movement in analysis runtime, violation classification completeness, delta noise between runs, not just issue counts. A report is complete only when ownership and closure action are explicit.

Metric focus: analysis runtime, violation classification completeness, delta noise between runs

• Track analysis runtime, violation classification completeness, delta noise between runs 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.

Reports and artifacts

• critical by owner

• waiver quality

• review gate status

• closure trend

Mini case study

Pass rates improved while critical waivers aged out of policy; dashboard exposed hidden risk.

Debug branches

• Separate quality from quantity metrics

• enforce waiver expiry

• run gate checklists consistently

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.
