This edition has been checked and reviewed many times over, but once again, all mistakes are ours. Why was SystemVerilog Created?
SystemVerilog for Verification 3rd edition
In the late s, the Verilog Hardware Description Language HDL became the most widely used language for describing hardware for simulation and synthesis. However, the first two versions standardized by the IEEE and had only simple constructs for creating tests. As design sizes outgrew the verification capabilities of the language, commercial Hardware Verification Languages HVLs such as OpenVera and e were created. Companies that did not want to pay for these tools instead spent hundreds of man-years creating their own custom tools.
This productivity crisis, along with a similar one on the design side, led to the creation of Accellera, a consortium of EDA companies and users who wanted to create the next generation of Verilog. Merging these two standards into a single one means there is now one language, SystemVerilog, for both design and verification.
Importance of a Unified Language Verification is generally viewed as a fundamentally different activity from design. This split has led to the development of narrowly focused languages for verification and to the bifurcation of engineers into two largely independent disciplines. This specialization has created substantial bottlenecks in terms of communication between the two groups. SystemVerilog addresses this issue with its capabilities for both camps.
SystemVerilog for Verification
Neither team has to give up any capabilities it needs to be successful, but the unification of both syntax and semantics of design and verification tools improves communication. For example, while a design engineer may not be able to write an object-oriented testbench environment, it is fairly straightforward to read such a test and understand what is happening, enabling both the design and verification engineers to work together to identify and fix problems.
Likewise, a designer understands the inner workings of his or her block, and is the best person to write assertions about it, but a verification engineer may have a broader view needed to create assertions between blocks. Another advantage of including the design, testbench, and assertion constructs in a single language is that the testbench has easy access to all parts of the environment without requiring a specialized Application Programming Interface API.
The value of an HVL is its ability to create high-level, flexible tests, not its loop constructs or declaration style. Importance of Methodology There is a difference between learning the syntax of a language and learning how to use a tool. This book focuses on techniques for verification using constrainedrandom tests that use functional coverage to measure progress and direct the verification.
As the chapters unfold, language and methodology features are shown side by side. For more on methodology, see Bergeron et al. The most valuable benefit of SystemVerilog is that it allows the user to construct reliable, repeatable verification environments, in a consistent syntax, that can be used across multiple projects.

This book focuses on the constructs used to verify a design. There are many ways to solve a problem using SystemVerilog. This book explains the tradeoffs between alternative solutions.
Chapter 1, Verification Guidelines, presents verification techniques to serve as a foundation for learning and using the SystemVerilog language. These guidelines emphasize coverage-driven random testing in a layered testbench environment. Chapter 2, Data Types, covers the new SystemVerilog data types such as arrays, structures, enumerated types, and packed arrays and structures.
Chapter 3, Procedural Statements and Routines, shows the new procedural statements and improvements for tasks and functions. Chapter 4, Connecting the Testbench and Design, shows the new SystemVerilog verification constructs, such as program blocks, interfaces, and clocking blocks, and how they are used to build your testbench and connect it to the design under test.
Chapter 5, Basic OOP, is an introduction to Object-Oriented Programming, explaining how to build classes, construct objects, and use handles. Chapter 7, Threads and Interprocess Communication, shows how to create multiple threads in your testbench, use interprocess communication to exchange data between these threads and synchronize them. Chapter 9, Functional Coverage, explains the different types of coverage and how you can use functional coverage to measure your progress as you follow a verification plan.
SystemVerilog for Verification, third edition
Chapter 10, Advanced Interfaces, shows how to use virtual interfaces to simplify your testbench code, connect to multiple design configurations, and create interfaces with procedural code so your testbench and design can work at a higher level of abstraction.
Chapter 11, A Complete SystemVerilog Testbench, shows a constrained random testbench using the guidelines shown in Chapter 8. Several tests are shown to demonstrate how you can easily extend the behavior of a testbench without editing the original code, which always carries risk of introducing new bugs.
Preface xi Icons used in this book Table i. There are over code samples and detailed explanations.
Learn the inner workings of such concepts as polymorphism, callbacks, and factory patterns. In addition, the book includes hundreds of guidelines to make you more productive with the language, and also explanations for common coding mistakes so you can avoid these traps.
Plus Greg Tumbush has contributed homework questions from his college course on verification. SystemVerilog for Verification focuses on the best practices for verifying your design using the power of the language.
What is new in the third edition? This new edition of SystemVerilog for Verification has many improvements over the second edition that was published in The biggest change is that this edition can also be used as a textbook for an undergraduate or graduate course in verification of digital designs.
This book tries to include the latest relevant information. Once again, Chris and Greg have responded to feedback from readers, professors, and students about SystemVerilog concepts. Almost all of these conversations have been incorporated into this book as expanded explanations and code samples.Once again, Chris and Greg have responded to feedback from readers, professors, and students about SystemVerilog concepts.
Another advantage of including the design, testbench, and assertion constructs in a single language is that the testbench has easy access to all parts of the environment without requiring a specialized Application Programming Interface API. In , Greg left ON Semiconductor to form Tumbush Enterprises, where he has been consulting clients in the areas of design, verification, and backend to ensure first pass success.

If you create testbenches, you need this book.
