Use In connection with any form of information storage and retrieval, electronic adaptation, computer software, or by similar or dissimilar methodology now known or hereafter developed is forbidden. The use in this publication of trade names, trademarks, service marks and similar terms, even if they are not identified as such, is not to be taken as an expression of opinion as to whether or not they are subject to proprietary rights.
Nevertheless, the term is entirely applicable to the current evolution-arguably even a revolution-in functional verification for chip designs. Three converging forces are at work today: complexity, language, and methodology.
Far too many chips do not ship on first silicon due to functional bugs that should have been caught before tapeout. Hand-written simulation tests are being almost entirely replaced by constrained-random verification environments using functional coverage metrics to determine when to tape out.
Specification of assertions, constraints, and coverage points has become an essential part of the development process. The SystemVerilog language has been a major driver in the adoption of these advanced verification techniques.
SystemVerilog provides constructs for assertions, constraints, and coverage along with powerful object-oriented capabilities that foster reusable testbenches and verification components. The broad vendor support and wide industry adoption of System Veri log have directly led to mainstream use of constrained-random, coverage-driven verification environments. However, a language alone cannot guarantee successful verification. Such topics require a comprehensive verification methodology to tie together the advanced techniques and the features of the language in a systematic approach.
It was greeted with enormous enthusiasm by the industry and is used today on countless chip projects. It provides thorough coverage of all three forces at work. The complexity challenge is addressed by timely advice on verification planning and coherent descriptions of advanced verification techniques.
Many aspects of the SystemVerilog language, including its assertion and testbench constructs, are covered in detail. Finally, this book embraces the OVM as the guide for verification success, providing a real-world example deploying this methodology. Functional verification has never been easy, but it has become an overwhelming problem for many chip development teams.
This book should be a great comfort for both design and verification engineers. So grab a beverage of your choice and curl up in a comfortable chair to learn how to get started on your toughest verification problems. Spring Table ofContents Foreword Chapter 1: Verification Tools and Methodologies Black-Box Assertions Coverage Collection Current Value This period has witnessed the introduction of new tools, methodologies, languages, planning approaches, and management philosophies, all sharply focused on addressing this very visible, and increasingly difficult, aspect of product development.
Significant progress has been made during this period, culminating, in recent years, in the emergence and maturity of best-in-class tools and practices. These maturing technologies not only allow the functional verification challenge to be addressed today, but also provide a foundation on which much-needed future innovations will be based.
This means that having a deep understanding of, and hands-on skills in applying, these maturing technologies is mandatory for all engineers and technologists whose task is to address the current and future functional verification challenges. A hallmark of maturing technologies is the emergence of multi-vendor supported and standardized verification languages and libraries. SystemVerilog is an extension of Verilog IEEE Standard , and enhances features of Verilog by introducing new data types, constrained randomization, object-oriented programming, assertion constructs, and coverage constructs.
OVM, in tum, provides the methodology and the class library that enable the implementation of a verification environment according to best-in-class verification practices.
This book is intended for a wide range of readers. It can be used to learn functional verification methodology, the SystemVerilog language, and the OVM class library and its methodology. This book can also be used as a step-by-step guide for implementing a verification environment. In addition, the source code for the full implementation of the XBar verification environment can be used as a template for starting a new project. As such, this book can be used by engineers starting to learn the SystemVerilog language concepts and syntax, as well as advanced readers looking to achieve better verification quality in their next verification project.
I am especially grateful to David Tokic and Luis Morales for helping tum this book from a nascent idea into a viable target, to Susan Peterson for getting this project off the ground and for her infectious positive energy, and to Tom Anderson for his continued technical and logistical guidance and support throughout the life of this effort.
Special thanks also go to Sarah Cooper Lundell and Adam Sherer for valuable planning and technical discussions, and to Ben Kauffman, the technical editor. I would like to thank Cadence Design Systems and the Verification Alliance program for their generous support of this effort. The technical content of this book has benefited greatly from feedback by great engineers and technologists.
Special thanks go to David Pena and Zeev Kirshenbaum for itt-depth discussions on many parts of this book. In addition, technical feedback and discussions by individuals from a diverse set of companies have contributed significantly to improving the technical content of this book. I am especially grateful to these individuals whose nan:les and affiliations are listed below. Sasan Iman Santa Clara.

Free Evaluation Universal Verification Methodology UVM is an open source SystemVerilog library allowing creation of flexible, reusable verification components and assembling powerful test environments utilizing constrained random stimulus generation and functional coverage methodologies. Its main promise is to improve testbench reuse, make verification code more portable and create new market for universal, high-quality Verification IP Intellectual Property. Open Verification Methodology OVM is the library of objects and procedures for stimulus generation, data collection and control of verification process. As the first SystemVerilog-based verification library available on multiple simulators, OVM contributed significantly to the development of its successor, Universal Verification Methodology. Verification Methodology Manual VMM was the first successful and widely implemented set of practices for creation of reusable verification environments in SystemVerilog.
