There are already many books on formal verification, from academic to application-centric, and from tutorials for beginners to guides for advanced users. Many are excellent for their intended purpose; we recommend a few at the end of this book. But most start from the assumption that you have already committed to becoming a hands-on expert (or in some cases that you already are an expert). We feel that detailed tutorials are not the easiest place to extract the introductory view many of us are looking for - background, a general idea of how methods work, applications and how formal verification is managed in the overall verification objective. Since we're writing for a fairly wide audience, we cover some topics that some of you may consider elementary (why verification is hard), some we hope will be of general interest (elementary understanding of the technology) and others that may not immediately interest some readers (setting up a formal verification team). What we intentionally do not cover at all is how to become a hands-on expert.

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.

Introduction The purpose of this book is to provide insight and intuition into the analog and analog-mixed signal system verification. It is also a journey the author of this book has been through on the way to tackle practical design and verification challenges with state of art analog and mixed signal designs. Motivation for authoring this book The digital design verification skill set is very different than analog design and verification. Traditionally, the analog block level verification is performed by the analog designers, and digital design verification is performed by digital design verification engineer. Lack of cross domain skill set makes it challenging to perform verification at mixed-signal level. Hence, either analog designer engineer should learn advanced digital verification techniques or digital design verification engineer embrace analog verification to become analog-mixed signal verification engineer. This book is written keeping this new trend in mind, hence it covers digital design fundamentals, digital design verification as well as analog design fundamentals, and analog performance verification. Organization of this book Keeping the readers of analog verification or digital design verification background in mind, the book has first 5 chapters focused on the fundamentals of the analog design, digital design, and its verification. Chapter 6 and chapter 7 focuses on the analog-mixed signal design verification and behavioral modeling respectively. Chapter 8 is dedicated to the low power verification techniques. Chapter 1: Introduction to Analog Mixed Signal Verification This chapter discusses about the evolution of the verification methodologies, history of analog-mixed signal designs, applications, and future trends. Chapter 2: Analog Design Fundamentals The purpose of this chapter is to give an overview of the analog design fundamentals for digital design background engineers. Major focus is given on analog behavior, design criteria and their concept rather than design themselves, such as voltage/current reference, some of the basic key analog design properties such as gain, band width, basics of jitter, eye diagram, etc. Chapter 3: Digital Design Fundamentals In this chapter, we explain digital design flow, combinational and sequential logic design fundamentals, design for testability, concepts of timing, and timing verification. Chapter 4: Analog Verification This chapter focuses on analog performance verification and functional verification under the context of mixed signal design hierarchical verification rather than the detail performance analysis of the designs themselves. Chapter 5: Digital Design Verification This chapter explains the tools and methodologies that are evolved over the period that are predicated on predictable quality and verification efficiency. The chapter contains the sections on the coverage driven verification (CDV) methodology, assertion based verification (ABV) methodology, and overview of the CDV using Open Verification Methodology (OVM). Chapter 6: Analog-Mixed Signal Verification This chapter discusses about the AMS verification phases, choosing the right abstraction of DUT for a given verification challenge, AMS verification planning, testplanning for AMS design verification, and testbench development with re-use in mind. Chapter 7: Analog Behavioral Modeling This chapter explains about the applications of analog behavioral models, modeling methodology, simple examples of various analog behavioral modeling styles, selection of accuracy level of the models based on the verification plan, model verification, and signoff. Chapter 8: Low Power Verification The purpose of this chapter is to explain the low power design verification challenges, key low power design elements, low power design techniques, low power design and verification cycle, testplanning for low power design verification, power aware digital, and AMS simulations.

Principles of Verifiable RTL Design: A Functional Coding Style Supporting Verification Processes in Verilog explains how you can write Verilog to describe chip designs at the RT-level in a manner that cooperates with verification processes. This cooperation can return an order of magnitude improvement in performance and capacity from tools such as simulation and equivalence checkers. It reduces the labor costs of coverage and formal model checking by facilitating communication between the design engineer and the verification engineer. It also orients the RTL style to provide more useful results from the overall verification process. The intended audience for Principles of Verifiable RTL Design: A Functional Coding Style Supporting Verification Processes in Verilog is engineers and students who need an introduction to various design verification processes and a supporting functional Verilog RTL coding style. A second intended audience is engineers who have been through introductory training in Verilog and now want to develop good RTL writing practices for verification. A third audience is Verilog language instructors who are using a general text on Verilog as the course textbook but want to enrich their lectures with an emphasis on verification. A fourth audience is engineers with substantial Verilog experience who want to improve their Verilog practice to work better with RTL Verilog verification tools. A fifth audience is design consultants searching for proven verification-centric methodologies. A sixth audience is EDA verification tool implementers who want some suggestions about a minimal Verilog verification subset. Principles of Verifiable RTL Design: A Functional Coding Style Supporting Verification Processes in Verilog is based on the reality that comes from actual large-scale product design process and tool experience.

The fact that there are more embedded computers than general-purpose computers and that we are impacted by hundreds of them every day is no longer news. What is news is that their increasing performance requirements, complexity and capabilities demand a new approach to their design. Fisher, Faraboschi, and Young describe a new age of embedded computing design, in which the processor is central, making the approach radically distinct from contemporary practices of embedded systems design. They demonstrate why it is essential to take a computing-centric and system-design approach to the traditional elements of nonprogrammable components, peripherals, interconnects and buses. These elements must be unified in a system design with high-performance processor architectures, microarchitectures and compilers, and with the compilation tools, debuggers and simulators needed for application development. In this landmark text, the authors apply their expertise in highly interdisciplinary hardware/software development and VLIW processors to illustrate this change in embedded computing. VLIW architectures have long been a popular choice in embedded systems design, and while VLIW is a running theme throughout the book, embedded computing is the core topic. Embedded Computing examines both in a book filled with fact and opinion based on the authors many years of R&D experience. · Complemented by a unique, professional-quality embedded tool-chain on the authors' website, http://www.vliw.org/book · Combines technical depth with real-world experience · Comprehensively explains the differences between general purpose computing systems and embedded systems at the hardware, software, tools and operating system levels. · Uses concrete examples to explain and motivate the trade-offs.

Hardware/software co-verification is how to make sure that embedded system software works correctly with the hardware, and that the hardware has been properly designed to run the software successfully -before large sums are spent on prototypes or manufacturing. This is the first book to apply this verification technique to the rapidly growing field of embedded systems-on-a-chip(SoC). As traditional embedded system design evolves into single-chip design, embedded engineers must be armed with the necessary information to make educated decisions about which tools and methodology to deploy. SoC verification requires a mix of expertise from the disciplines of microprocessor and computer architecture, logic design and simulation, and C and Assembly language embedded software. Until now, the relevant information on how it all fits together has not been available. Andrews, a recognized expert, provides in-depth information about how co-verification really works, how to be successful using it, and pitfalls to avoid. He illustrates these concepts using concrete examples with the ARM core - a technology that has the dominant market share in embedded system product design. The companion CD-ROM contains all source code used in the design examples, a searchable e-book version, and useful design tools. * The only book on verification for systems-on-a-chip (SoC) on the market * Will save engineers and their companies time and money by showing them how to speed up the testing process, while still avoiding costly mistakes * Design examples use the ARM core, the dominant technology in SoC, and all the source code is included on the accompanying CD-Rom, so engineers can easily use it in their own designs
