Chip-level RDC Closure: Reports & Metrics

Reports and metrics

Reports & Metrics for Chip-level RDC Closure focuses on top-level RDC open count, subsystem handoff completeness, integration churn. The goal is to convert issue observations into mechanism-backed closure decisions.

Reports must explain risk movement in top-level RDC open count, subsystem handoff completeness, integration churn, not just issue counts. A report is complete only when ownership and closure action are explicit.

Metric focus: top-level RDC open count, subsystem handoff completeness, integration churn

• Track top-level RDC open count, subsystem handoff completeness, integration churn 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

RDC closure must connect IP assumptions to SoC reality.

Reports and artifacts

• top-level RDC opens

• reset simulation coverage

• chip integration blockers

• waiver backlog

Mini case study

Each IP was locally clean, but top-level sequencing violation created cross-subsystem boot intermittency.

Debug branches

• Audit subsystem assumptions

• stress chip-level reset scenarios

• close ownership gaps

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.
