Coverage Goals

The project aims for:

  • Functional Coverage: 100% of critical paths tested

  • Statement Coverage: 95% of VHDL statements exercised

  • Branch Coverage: 90% of conditional branches tested

  • Edge Case Coverage: All boundary conditions verified

Improving Coverage

To expand test coverage:

  1. Add missing testbenches for untested components

  2. Enhance existing tests with more comprehensive scenarios

  3. Implement assertion-based verification for better coverage metrics

  4. Add performance and timing tests for critical paths
