Abstract

We introduce comparative functional coverage --- a technique for comparing the coverage of multiple workloads --- and the tool in which it was implemented. The need to compare workloads and the use of functional coverage as a technique to explore data are not new. However, the use of functional coverage for comparing workloads has not been addressed as an answer to this long unanswered need. We describe our work in augmenting a functional coverage tool so it can handle multiple data sources. We present the data and an experiment that shows the usefulness of this method.
