Book Description
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.

Book Description
Functional verification is an art as much as a science. It requires not only creativity and cunning, but also a clear methodology to approach the problem. The Open Verification Methodology (OVM) is a leading-edge methodology for verifying designs at multiple levels of abstraction. It brings together ideas from electrical, systems, and software engineering to provide a complete methodology for verifying large scale System-on-Chip (SoC) designs. OVM defines an approach for developing testbench architectures so they are modular, configurable, and reusable. This book is designed to help both novice and experienced verification engineers master the OVM through extensive examples. It describes basic verification principles and explains the essentials of transaction-level modeling (TLM). It leads readers from a simple connection of a producer and a consumer through complete self-checking testbenches. It explains construction techniques for building configurable, reusable testbench components and how to use TLM to communicate between them. Elements such as agents and sequences are explained in detail.

Book Description
A comprehensive resource on Verilog HDL for beginners and experts Large and complicated digital circuits can be incorporated into hardware by using Verilog, a hardware description language (HDL). A designer aspiring to master this versatile language must first become familiar with its constructs, practice their use in real applications, and apply them in combinations in order to be successful. Design Through Verilog HDL affords novices the opportunity to perform all of these tasks, while also offering seasoned professionals a comprehensive resource on this dynamic tool. Describing a design using Verilog is only half the story: writing test-benches, testing a design for all its desired functions, and how identifying and removing the faults remain significant challenges. Design Through Verilog HDL addresses each of these issues concisely and effectively. The authors discuss constructs through illustrative examples that are tested with popular simulation packages, ensuring the subject matter remains practically relevant. Other important topics covered include: Primitives Gate and Net delays Buffers CMOS switches State machine design Further, the authors focus on illuminating the differences between gate level, data flow, and behavioral styles of Verilog, a critical distinction for designers. The book's final chapters deal with advanced topics such as timescales, parameters and related constructs, queues, and switch level design. Each chapter concludes with exercises that both ensure readers have mastered the present material and stimulate readers to explore avenues of their own choosing. Written and assembled in a paced, logical manner, Design Through Verilog HDL provides professionals, graduate students, and advanced undergraduates with a one-of-a-kind resource.

Book Description
The Verilog Hardware Description Language was first introduced in 1984. Over the 20 year history of Verilog, every Verilog engineer has developed his own personal “bag of tricks” for coding with Verilog. These tricks enable modeling or verifying designs more easily and more accurately. Developing this bag of tricks is often based on years of trial and error. Through experience, engineers learn that one specific coding style works best in some circumstances, while in another situation, a different coding style is best. As with any high-level language, Verilog often provides engineers several ways to accomplish a specific task. Wouldn’t it be wonderful if an engineer first learning Verilog could start with another engineer’s bag of tricks, without having to go through years of trial and error to decide which style is best for which circumstance? That is where this book becomes an invaluable resource. The book presents dozens of Verilog tricks of the trade on how to best use the Verilog HDL for modeling designs at various level of abstraction, and for writing test benches to verify designs. The book not only shows the correct ways of using Verilog for different situations, it also presents alternate styles, and discusses the pros and cons of these styles.

Book Description
SystemVerilog language consists of three categories of features -- Design, Assertions and Testbench. Assertions add a whole new dimension to the ASIC verification process. Engineers are used to writing testbenches in verilog that help verify their design. Verilog is a procedural language and is very limited in capabilities to handle the complex ASICs built today. SystemVerilog assertions (SVA) is a declarative language. The temporal nature of the language provides excellent control over time and allows mulitple processes to execute simultaneously. This provides the engineers a very strong tool to solve their verification problems. The language is still new and the thinking is very different from the user's perspective when compared to standard verilog language. There is not enough expertise or intellectual property available as of today in the field. While the language has been defined very well, there is no practical guide that shows how to use the language to solve real verification problems. This book is a practical guide that will help people to understand this new language and adopt assertion based verification methodology quickly.
