Test Coverage
=============

Overview of test coverage metrics and strategies.

.. note::

   This section provides details about test coverage analysis and metrics.

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
