This course is intended for people with little or no experience of SVA, Formal Analysis (FA) and JasperGold®. SystemVerilog Assertions (SVA) is a very concise and powerful language for defining behaviors (properties) which a design should have. Its concise nature makes it deceptively difficult to intuitively understand all consequences of the property being written and, hence, very easy for users to make damaging mistakes. This course introduces SVA in a very pragmatic way, including how to code SVA properties which are efficient for Formal Analysis. Formal Analysis is a completely different paradigm from the older and more widely adopted methods of verification like simulation. As such, the fundamental objectives, capabilities, limitations, setup and initialization requirements, in addition to analysis and interpretation of results, need to be well understood before we can make effective use of FA tools and specialized JasperGold Apps. Formal is capable of much more than simulation alone can deliver but optimization techniques often need to be applied to get conclusive results within realistic timescales. These techniques are extremely difficult to discover or pick up "as one goes along" without training or expert assistance. Anyone can run an FA tool but experience is needed to get conclusive results in a realistic timeframe which are completely understood. This course is intended as a shortcut to gaining that experience. The course has 60% lectures and 40% hands-on labs.
After completing this course, you will be able to:
- Define reusable, functionally correct SVA properties which are efficient for Formal tools. These shall make use of abstract auxiliary code to simplify descriptions, make code maintenance easier, reduce debug time and reduce tool proof runtime.
- Set up, run and analyze results from Formal Analysis.
- Identify designs upon which formal is likely to be successful, while understanding formal complexity issues and how to identify and overcome them.
- Identify situations where Initial Value Abstractions (IVAs) would be appropriate and how to define them.
- Set up and run the JasperGold Apps named Superlint and X-Propagation
- Use a systematic process of property development to approach a completely new verification problem.
