The focus of Assertion-Based Design is three-fold: How to specify assertions; how to create and adopt a methodology that supports assertion-based design (predominately for RTL design); and what to do with the assertions and methodology once you have them. To support these three over-arching goals, the authors showcase multiple forms of assertion specification: Accellera Open Verification Library (OVL), Accellera Property Specification Language (PSL), and Accellera SystemVerilog. The recommendations and claims the authors make in this book are based on their combined actual experiences in applying an assertion-based methodology to real design and verification as well as their work in developing industry assertion standards.
