Abstract
Aggregation of coverage data for a design-under-test (DUT) can be performed using a coverage testbench without running any simulations on the DUT. Stimulus data that was used previously for performing different simulations on the DUT can be saved in a database. The coverage testbench can read the saved stimulus data and aggregate the coverage data from the stimulus data using a coverage model. When the DUT is updated, the coverage model can be updated, and updated coverage data can be collected using the coverage testbench without re-running the simulations on the DUT.
