mental improvements during the same period. What is clearly needed in verification techniques and technology is the equivalent of a synthesis productivity breakthrough. In the second edition of Writing Testbenches, Bergeron raises the verification level of abstraction by introducing coverage-driven constrained-random transaction-level self-checking testbenches all made possible through the introduction of hardware verification languages (HVLs), such as e from Verisity and OpenVera from Synopsys. The state-of-art methodologies described in Writing Test benches will contribute greatly to the much-needed equivalent of a synthesis breakthrough in verification productivity. I not only highly recommend this book, but also I think it should be required reading by anyone involved in design and verification of today's ASIC, SoCs and systems. Harry Foster Chief Architect Verplex Systems, Inc. xviii Writing Testbenches: Functional Verification of HDL Models PREFACE If you survey hardware design groups, you will learn that between 60% and 80% of their effort is now dedicated to verification.

The Second Edition ofWriting Testbenches, Functional Verification of HDL Modelspresents the latest verification techniques to produce fully functional first silicon ASICs, systems-on-a-chip (SoC), boards and entire systems. From the Foreword: Building on the first edition, " ...the most successful and popular contemporary verification textbook", the author raises the verification level of abstraction by introducing coverage-driven constrained random transaction-level self-checking testbenches - all made possible through the introduction of hardware verification languages (HVLs) such as e from Verisity and OpenVera from Synopsys...."(Harry Foster, Chief Architect, Verplex Systems, Inc.) Topics includedin the new Second Edition: *Discussions on OpenVera and e; *Approaches for writing constrainable random stimulus generators; *Strategies for making testbenches self-checking; *A clear blueprint of a verification process that aims for first time success; *Recent advances in functional verification such as coverage-driven verification process; *VHDL and Verilog language semantics; *The semantics are presented in new verification-oriented languages; *Techniques for applying stimulus and monitoring the response of a design; *Behavioral modeling using non-synthesizeable constructs and coding style; *Updated for Verilog 2001.

One of the biggest challenges in chip and system design is determining whether the hardware works correctly. That is the job of functional verification engineers and they are the audience for this comprehensive text from three top industry professionals. As designs increase in complexity, so has the value of verification engineers within the hardware design team. In fact, the need for skilled verification engineers has grown dramatically--functional verification now consumes between 40 and 70% of a project's labor, and about half its cost. Currently there are very few books on verification for engineers, and none that cover the subject as comprehensively as this text. A key strength of this book is that it describes the entire verification cycle and details each stage. The organization of the book follows the cycle, demonstrating how functional verification engages all aspects of the overall design effort and how individual cycle stages relate to the larger design process. Throughout the text, the authors leverage their 35 plus years experience in functional verification, providing examples and case studies, and focusing on the skills, methods, and tools needed to complete each verification task. Comprehensive overview of the complete verification cycle Combines industry experience with a strong emphasis on functional verification fundamentals Includes real-world case studies
