Course Description
This course is intended for users of JasperGold® wishing to improve Formal Verification Performance by using advanced techniques. There is a 50/50 split between lectures and hands-on labs, which allows the user to gain experience of the advanced techniques discussed in the course. Advanced property development techniques are shown with numerous real-life code examples utilizing techniques such as non-determinism, relaxing checks, reducing formal complexity in general and for liveness properties and fairness constraints,data tagging and more. In addition, how to detect, debug and fix over-constraining arising from conflicts and deadends is discussed. This course also covers how to make abstractions and reductions of the DUT to improve formal performance and how to use tool features to understand where design complexity is coming from and hence address how to reduce it. Finally, the course teaches methods of how to couple a design abstraction with a specialized checker to achieve better performance. Implementation of different kinds of formal scoreboards are discussed: for example, CAM tables and Fuzzy Scoreboards.
This is an Engineer Explorer series course. The Engineer Explorer courses explore advanced topics.
Learning Objectives
After attending the course, you will be able to:
