Automating code coverage closure
Questa Increase Coverage uses formal analysis to help design and verification teams close coverage gaps faster by identifying truly unreachable code and intelligently guiding verification effort.
Key Features:
- Automated Coverage Closure – Analyzes simulation results and applies formal techniques to close stubborn code coverage holes.
- Dead Code Detection – Identifies unreachable logic and eliminates the need to write futile tests.
- Automatic Waiver Generation – Generates waivers for proven unreachable code to streamline reporting.
- Guided Debug – Flags hard-to-reach code that may require design refactoring or targeted tests.
- UCDB Integration – Works with Unified Coverage Database (UCDB) for seamless data aggregation.
- Flow Integration – Fully integrated with QuestaSim and Verification Management tools.
- Improves Verification Efficiency – Focuses engineering effort where it truly matters.
- Design Quality Insights – Highlights design complexity and verification bottlenecks.
- Reduces Waste – Avoids time spent on unreachable paths and reduces unnecessary test development.
- Speeds Closure Signoff – Helps teams reach 100% code coverage goals confidently and efficiently.
