Recently on this blog, a series of related posts from Breker, Jasper, and OneSpin discussed formal analysis and its potential for playing a greater role in the verification process. We think that it’s important for The Breker Trekker to address topics in verification beyond our own technology and to provide occasional commentary on technology and the world of EDA in general. However, this recent focus on formal has caused some readers to wonder whether we consider ourselves to be in the formal market.
The short answer is “no” but there is some overlap in the technologies that we use and the techniques employed for formal analysis. Regular readers know that the foundation for our products is a graph-based scenario model that captures both the intended behavior of your SoC design and your system-level test plan. We can automatically extract system coverage from this model, with the model and coverage interacting in interesting ways. Let’s consider to what extent this is formal technology.
