Opis

Integrating formal property verification (FPV) into an existing design process raises several interesting questions. Have I written enough properties? Have I written a consistent set of properties? What should I do when the FPV tool runs into capacity issues? This book develops the answers to these questions and fits them into a roadmap for formal property verification a roadmap that shows how to glue FPV technology into the traditional validation flow. A Roadmap for Formal Property Verification explores the key issues in this powerful technology through simple examples you do not need any background on formal methods to read most parts of this book. "

Recenzje

"This book is a "must-read" for anyone who needs a broad and deep understanding of  assertion-based verification technology and methodology. It gives an in-depth overview of the logic behind, and algorithms for, reasoning about design behavior using assertions. The book also presents advanced methods for checking consistency and coverage of an assertion-based specification, for maintaining completeness of a specification as it is refined, and for leveraging assertions for automatic test generation in constrained random simulation.
Detailing both established practice and recent developments, "A Roadmap for Formal Property Verification" is a valuable reference for insight into both the present and the future of assertion-based verification." (Erich Marschner, Senior Architect, Systems and Functional Verification, Cadence Design Systems, and Co-Chair, Accellera Formal Verification Technical Committee (FVTC)
