Formal equivalence is a well-established topic in EDA. I will quickly review Boolean equivalence and talk about some difficult problems. Then I will discuss sequential equivalence and cite several different approaches to its definition and solution. Finally, a discussion of transaction-level to RT level equivalence will be discussed focusing on our new Hector technology and some competitors. The main point is that equivalence verification is necessary for enabling various approaches to synthesis and other EDA tools. For example, Hector is necessary to enable ESL design.
