Overview

Questa Increase Coverage

Flagging of code coverage items that are difficult to reach by formal techniques and haven’t been hit in simulation; thus providing a valuable measure of verification complexity. This guides engineers to change their designs to make them more easily verifiable.

Key features

Exhaustively identifies dead code areas

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.

Formal proof that the code can be safely ignored

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.

Code coverage’s “last mile” problem

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.
