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.

Code Coverage Closure

Formal Proof That the Code Can be Safely Ignored

<p>Questa CoverCheck 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.</p>

Questa CoverCheck Waiver

Target Coverage Holes

Code Coverage’s “Last Mile” Problem

<p>Questa CoverCheck automatically traverses your DUT&#39;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 Management analyses and progress reporting.</br></br></p>
