S10 — DV Coverage Closure

To close verification coverage gaps, you can analyze URG reports to map missing code and functional coverage to DUT signals and covergroups, then classify gaps to generate exclusion files and test stubs.

The best way to classify DV coverage gaps for milestone sign-off is to categorize them into excludable, coverable, and requires_analysis buckets, automating the generation of exclusion files and sign-off data.

Coverage closure requires cross-referencing assertion and regression data to comprehensively identify coverage gaps, ensuring milestone evaluation and sign-off reporting consolidate URG, regression, and assertion inputs.

You generate exclusion files from functional coverage holes by analyzing the merged.vdb database to identify coverable and excludable gaps, automatically producing per-type exclusion files to drive remediation.

When coverage gaps are classified as requires_analysis during verification, it indicates complex holes needing manual review before deciding whether to generate exclusion files or create test stubs for remediation.
