CDC Signoff Dashboard: Step-by-Step Walkthrough

Step-by-Step Walkthrough for CDC Signoff Dashboard.

Step-by-step analysis walkthrough

Use this sequence when owning CDC Signoff Dashboard in a signoff review.

  1. Inspect warning class and severity.

  2. Trace crossing endpoints and domains.

  3. Check protocol/reset assumptions against spec.

  4. Review synchronizer or FIFO implementation detail.

  5. Run focused assertion or formal check.

  6. Draft fix options with risk and schedule impact.

  7. Execute regression and publish closure memo.

Artifacts to collect

  • weekly CDC dashboard, severity breakdown, closure forecast

  • crossing inventory

  • waiver board notes

  • regression report

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.

Principal CDC/RDC review addendum

Dashboarding translates thousands of crossings into actionable closure metrics by severity, block, owner, and risk state.

Metric: critical violations trend, closure burn-down, owner SLA adherence
