No matter how many clever directed test you write, no matter how many different random seeds you try, the coverage score simply flat-lines. In parallel, specifying waivers to deliberately exclude unused IP configurations from the analysis can be a tedious and error prone manual process.
Code coverage closure
Questa Increase Coverage is an automatic formal solution for achieving code coverage closure faster. The tool addresses an incontrovertible fact of verification: no matter the combination of techniques used, and even after running an exhaustive battery of tests, some fraction of uncovered code always remains.
Target coverage holes
Questa Increase Coverage automatically traverses your DUT's state spaces and identifies unreachable areas, enables the user to "waive"/exclude items from future analyses, and pipe all results into a Unified Coverage DataBase (UCDB) for inclusion in Questa Verification IQ analyses and progress reporting.
