Assertion-based IP is much more than a comprehensive set of related assertions. It is a full-fledged reusable and configurable transaction-level verification component, which is used to detect both interesting and incorrect behaviors. Upon detecting interesting or incorrect behavior, the assertion-based IP alerts other verification components within a simulation environment, which are responsible for taking appropriate action. The focus of this book is to bring the assertion discussion up to a higher level and introduce a process for creating effective, reusable, assertion-based IP, which easily integrates with the user existing verification environment, in other words the testbench infrastructure. The guiding principles promoted in this book when creating an assertion-based IP monitor are: modularity—assertion-based IP should have a clear separation between detection and action clarity—assertion-based IP should be written initially focusing on capturing intent (versus optimizations) A unique feature of this book is the fully worked out, detailed examples. The concepts presented in the book are drawn from the authors’ experience developing assertion-based IP, as well as general assertion-based techniques. Creating Assertion-Based IP is an important resource for design and verification engineers. From the Foreword: Creating Assertion-Based IP …reduces to process the creation of one of the most valuable kinds of VIP: assertion-based VIP…This book will serve as a valuable reference for years to come.
