Address Missing Coverage

Filter coverage results and address gaps

To focus your coverage results on the aspects of your design that you want to test, you use filters to exclude elements or justify unsatisfied outcomes that you do not intend to exercise. The remaining coverage gaps might indicate insufficient testing, missing requirements, or incorrect implementation. To address these coverage gaps, you can then create additional tests, extend existing tests, refine requirements, or edit your model.
