Evaluating coverage collection using the VEasy functional verification tool suite

This paper describes a performance evaluation of coverage collection on different simulators. It also describes how coverage is collected using VEasy, a tool suite developed specifically for aiding the process of Functional Verification. A Verilog module is used as an example of where each coverage metric applies. The block and toggle coverage collection algorithms used in VEasy are presented and explained in detail. Finally, the results show that the algorithms used in VEasy are capable of performing coverage collection with a lower simulation overhead when compared with commercial simulators.
