Functional verification remains one of the single biggest challenges in the development of complex system-on-chip (SoC) devices. Despite the introduction of successive new technologies, the gap between design capability and verification confidence continues to widen. The biggest problem is that these diverse new technologies have led to a proliferation of verification point tools, most with their own languages and methodologies. Fortunately, a solution is at hand. SystemVerilog is a unified language that serves both design and verification engineers by including RTL design constructs, assertions and a rich set of verification constructs. SystemVerilog is an industry standard that is well supported by a wide range of verification tools and platforms. A single language fosters the development of a unified simulation-based verification tool or platform. Consolidation of point tools into a unified platform and convergence to a unified language enable the development of a unified verification methodology that can be used on a wide range of SoC projects. ARM and Synopsys have worked together to define just such a methodology in the SystemVerilog Verification Methodology Manual (VMM). their customers. The SystemVerilog VMM is a blueprint for verification success, guiding SoC teams in building a reusable verification environment taking full advantage of design-for-verification techniques, constrained-random stimulus generation, coverage-driven verification, formal verification and other advanced technologies to help solve their current and future verification problems. This book is appropriate for anyone involved in the design or verification of a complex chip or anyone who would like to know more about the capabilities of SystemVerilog. Following the SystemVerilog VMM will give SoC development teams and project managers the confidence needed to tape out a complex design, secure in the knowledge that the chip will function correctly in the real world.

Verification is too often approached in an ad hoc fashion. Visually inspecting simulation results is no longer feasible and the directed test-case methodology is reaching its limit. Moore's Law demands a productivity revolution in functional verification methodology.

Writing Testbenches Using SystemVerilog offers a clear blueprint of a verification process that aims for first-time success using the SystemVerilog language. From simulators to source management tools, from specification to functional coverage, from I's and O's to high-level abstractions, from interfaces to bus-functional models, from transactions to self-checking testbenches, from directed testcases to constrained random generators, from behavioral models to regression suites, this book covers it all.

Writing Testbenches Using SystemVerilog presents many of the functional verification features that were added to the Verilog language as part of SystemVerilog. Interfaces, virtual modports, classes, program blocks, clocking blocks and others SystemVerilog features are introduced within a coherent verification methodology and usage model.

Writing Testbenches Using SystemVerilog introduces the reader to all elements of a modern, scalable verification methodology. It is an introduction and prelude to the verification methodology detailed in the Verification Methodology Manual for SystemVerilog. It is a SystemVerilog version of the author's bestselling book Writing Testbenches: Functional Verification of HDL Models.

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."

Offers users the first resource guide that combines both the methodology and basics of SystemVerilog Addresses how all these pieces fit together and how they should be used to verify complex chips rapidly and thoroughly. Unique in its broad coverage of SystemVerilog, advanced functional verification, and the combination of the two.

Writing Testbenches: Functional Verification of HDL Models first introduces the necessary concepts and tools of verification, then describes a process for carrying out an effective functional verification of a design. This book also presents techniques for applying a stimulus and monitoring the response of a design by abstracting the operations using bus-functional models. The architecture of testbenches built around these bus-functional models is important for minimizing development and maintenance effort. Behavioral modeling is another important concept presented in this book. It is used to parallelize the implementation and verification of a design and to perform more efficient simulations. For many, behavioral modeling is synonymous with synthesizeable or RTL modeling. In this book, the term 'behavioural' is used to describe any model that adequately emulates the functionality of a design, usually using non-synthesizeable constructs and coding style. Writing Testbenches: Functional Verification of HDL Models focuses on the functional verification of hardware designs using either VHDL or Verilog.The reader should have at least a basic knowledge of one of the languages. Ideally, he or she should have experience in writing synthesizeable models and be familiar with running a simulation using any of the available VHDL or Verilog simulators. From the Foreword 'With gate counts and system complexity growing exponentially, engineers confront the most perplexing challenge in product design: functional verification. The bulk of the time consumed in the design of new ICs and systems is now spent on verification. New and interesting design technologies like physical synthesis and design reuse that create ever- larger designs only aggravate the problem. What the EDA tool industry has continuously failed to realize is that the real problem is not how to create a 12 million gate IC that runs at 600 MHz, but how to verify it. This text marks the first genuine effort at defining a verification methodology that is independent of both tools and applications. Engineers now have a true reference text for quickly and accurately verifying the functionality of their designs.' Michael Horne, President and CEO, Qualis Design Corporation
