| functional verification basics: Principles of Functional Verification Andreas Meyer, 2003-12-05 As design complexity in chips and devices continues to rise, so, too, does the demand for functional verification. Principles of Functional Verification is a hands-on, practical text that will help train professionals in the field of engineering on the methodology and approaches to verification.In practice, the architectural intent of a device is necessarily abstract. The implementation process, however, must define the detailed mechanisms to achieve the architectural goals. Based on a decade of experience, Principles of Functional Verification intends to pinpoint the issues, provide strategies to solve the issues, and present practical applications for narrowing the gap between architectural intent and implementation. The book is divided into three parts, each building upon the chapters within the previous part. Part One addresses why functional verification is necessary, its definition and goals. In Part Two, the heart of the methodology and approaches to solving verification issues are examined. Each chapter in this part ends with exercises to apply what was discussed in the chapter. Part Three looks at practical applications, discussing project planning, resource requirements, and costs. Each chapter throughout all three parts will open with Key Objectives, focal points the reader can expect to review in the chapter.* Takes a holistic approach to verification issues* Approach is not restricted to one language* Discussed the verification process, not just how to use the verification language |
| functional verification basics: Writing Testbenches: Functional Verification of HDL Models Janick Bergeron, 2012-12-06 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. |
| functional verification basics: ASIC/SoC Functional Design Verification Ashok B. Mehta, 2017-06-28 This book describes in detail all required technologies and methodologies needed to create a comprehensive, functional design verification strategy and environment to tackle the toughest job of guaranteeing first-pass working silicon. The author first outlines all of the verification sub-fields at a high level, with just enough depth to allow an engineer to grasp the field before delving into its detail. He then describes in detail industry standard technologies such as UVM (Universal Verification Methodology), SVA (SystemVerilog Assertions), SFC (SystemVerilog Functional Coverage), CDV (Coverage Driven Verification), Low Power Verification (Unified Power Format UPF), AMS (Analog Mixed Signal) verification, Virtual Platform TLM2.0/ESL (Electronic System Level) methodology, Static Formal Verification, Logic Equivalency Check (LEC), Hardware Acceleration, Hardware Emulation, Hardware/Software Co-verification, Power Performance Area (PPA) analysis on a virtual platform, Reuse Methodology from Algorithm/ESL to RTL, and other overall methodologies. |
| functional verification basics: Principles of Verifiable RTL Design Lionel Bening, Harry D. Foster, 2007-05-08 System designers, computer scientists and engineers have c- tinuously invented and employed notations for modeling, speci- ing, simulating, documenting, communicating, teaching, verifying and controlling the designs of digital systems. Initially these s- tems were represented via electronic and fabrication details. F- lowing C. E. Shannon’s revelation of 1948, logic diagrams and Boolean equations were used to represent digital systems in a fa- ion that de-emphasized electronic and fabrication detail while revealing logical behavior. A small number of circuits were made available to remove the abstraction of these representations when it was desirable to do so. As system complexity grew, block diagrams, timing charts, sequence charts, and other graphic and symbolic notations were found to be useful in summarizing the gross features of a system and describing how it operated. In addition, it always seemed necessary or appropriate to augment these documents with lengthy verbal descriptions in a natural language. While each notation was, and still is, a perfectly valid means of expressing a design, lack of standardization, conciseness, and f- mal definitions interfered with communication and the understa- ing between groups of people using different notations. This problem was recognized early and formal languages began to evolve in the 1950s when I. S. Reed discovered that flip-flop input equations were equivalent to a register transfer equation, and that xvi tor-like notation. Expanding these concepts Reed developed a no- tion that became known as a Register Transfer Language (RTL). |
| functional verification basics: Advanced Verification Techniques Leena Singh, Leonard Drucker, Neyaz Khan, 2004-06-08 As chip size and complexity continues to grow exponentially, the challenges of functional verification are becoming a critical issue in the electronics industry. It is now commonly heard that logical errors missed during functional verification are the most common cause of chip re-spins, and that the costs associated with functional verification are now outweighing the costs of chip design. To cope with these challenges engineers are increasingly relying on new design and verification methodologies and languages. Transaction-based design and verification, constrained random stimulus generation, functional coverage analysis, and assertion-based verification are all techniques that advanced design and verification teams routinely use today. Engineers are also increasingly turning to design and verification models based on C/C++ and SystemC in order to build more abstract, higher performance hardware and software models and to escape the limitations of RTL HDLs. This new book, Advanced Verification Techniques, provides specific guidance for these advanced verification techniques. The book includes realistic examples and shows how SystemC and SCV can be applied to a variety of advanced design and verification tasks. - Stuart Swan |

| functional verification basics: Comprehensive Functional Verification Bruce Wile, John Goss, Wolfgang Roesner, 2005-05-26 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 |
| functional verification basics: Open Verification Methodology Cookbook Mark Glasser, 2009-07-24 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. |

| functional verification basics: Rigorous Software Development José Bacelar Almeida, Maria João Frade, Jorge Sousa Pinto, Simão Melo de Sousa, 2011-01-04 The use of mathematical methods in the development of software is essential when reliable systems are sought; in particular they are now strongly recommended by the official norms adopted in the production of critical software. Program Verification is the area of computer science that studies mathematical methods for checking that a program conforms to its specification. This text is a self-contained introduction to program verification using logic-based methods, presented in the broader context of formal methods for software engineering. The idea of specifying the behaviour of individual software components by attaching contracts to them is now a widely followed approach in program development, which has given rise notably to the development of a number of behavioural interface specification languages and program verification tools. A foundation for the static verification of programs based on contract-annotated routines is laid out in the book. These can be independently verified, which provides a modular approach to the verification of software. The text assumes only basic knowledge of standard mathematical concepts that should be familiar to any computer science student. It includes a self-contained introduction to propositional logic and first-order reasoning with theories, followed by a study of program verification that combines theoretical and practical aspects - from a program logic (a variant of Hoare logic for programs containing user-provided annotations) to the use of a realistic tool for the verification of C programs (annotated using the ACSL specification language), through the generation of verification conditions and the static verification of runtime errors. |

| functional verification basics: Verification Techniques for System-Level Design Masahiro Fujita, Indradeep Ghosh, Mukul Prasad, 2010-07-27 This book will explain how to verify SoC (Systems on Chip) logic designs using formal and semiformal verification techniques. The critical issue to be addressed is whether the functionality of the design is the one that the designers intended. Simulation has been used for checking the correctness of SoC designs (as in functional verification), but many subtle design errors cannot be caught by simulation. Recently, formal verification, giving mathematical proof of the correctness of designs, has been gaining popularity.For higher design productivity, it is essential to debug designs as early as possible, which this book facilitates. This book covers all aspects of high-level formal and semiformal verification techniques for system level designs.• First book that covers all aspects of formal and semiformal, high-level (higher than RTL) design verification targeting SoC designs.• Formal verification of high-level designs (RTL or higher).• Verification techniques are discussed with associated system-level design methodology. |

| functional verification basics: A Practical Guide for SystemVerilog Assertions Srikanth Vijayaraghavan, Meyyappan Ramanathan, 2006-07-04 SystemVerilog language consists of three very specific areas of constructs -- design, assertions and testbench. Assertions add a whole new dimension to the ASIC verification process. Assertions provide a better way to do verification proactively. Traditionally, engineers are used to writing verilog test benches that help simulate their design. Verilog is a procedural language and is very limited in capabilities to handle the complex Asic's built today. SystemVerilog assertions (SVA) are a declarative and temporal language that provides excellent control over time and parallelism. This provides the designers a very strong tool to solve their verification problems. While the language is built solid, the thinking is very different from the user's perspective when compared to standard verilog language. The concept is still very new and there is not enough expertise in the field to adopt this methodology and be successful. 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 will be the practical guide that will help people to understand this new methodology. Today's SoC complexity coupled with time-to-market and first-silicon success pressures make assertion based verification a requirement and this book points the way to effective use of assertions. Satish S. Iyengar, Director, ASIC Engineering, Crimson Microsystems, Inc. This book benefits both the beginner and the more advanced users of SystemVerilog Assertions (SVA). First by introducing the concept of Assertion Based Verification (ABV) in a simple to understand way, then by discussing the myriad of ideas in a broader scope that SVA can accommodate. The many real life examples, provided throughout the book, are especially useful. Irwan Sie, Director, IC Design, ESS Technology, Inc. SystemVerilogAssertions is a new language that can find and isolate bugs early in the design cycle. This book shows how to verify complex protocols and memories using SVA with seeral examples. This book is a good reference guide for both design and verification engineers. Derick Lin, Senior Director, Engineering, Airgo Networks, Inc. |

| functional verification basics: Finding Your Way Through Formal Verification Bernard Murphy, Manish Pandey, Sean Safarpour, 2018-03-06 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. |
| functional verification basics: Software Verification and Analysis Janusz Laski, William Stanley, 2009-04-29 “The situation is good, but not hopeless” (Polish folk wisdom) The text is devoted to the Software Analysis and Testing (SAT) methods and s- porting tools for assessing and, if possible, improving software quality, specifically its correctness. The term quality assurance is avoided for it is this author’s firm belief that in the current state of the art that goal is unattainable, a plethora of “gu- anteed” solutions to the problem notwithstanding. Therefore, the rather awkward phrase “improving correctness” is to be understood as an effort to minimize the number of residual programming faults (“bugs”) and their impact on the software’s behavior, that is, to make the faults tolerable. It is clear that such a minimalist approach is a result of frustration. Indeed, having spent years developing software and teaching (preaching?) “How to do it right,” I still do not know how to go about it with any degree of certainty! It appears then I probably should stop right now, for who with a modicum of common sense would reach for a text that does not offer salvation but (as will be seen) hard work and misery? If I intend to continue, it is only that I suspect there are many professionals out there who have similar doubts. And they are the intended audience of this project. The philosophical underpinning of the text is the importance of sound engine- ing practices in software development. |
| functional verification basics: Logic Design and Verification Using SystemVerilog (Revised) Donald Thomas, 2016-03-01 SystemVerilog is a Hardware Description Language that enables designers to work at the higher levels of logic design abstractions that match the increased complexity of current day integrated circuit and field-programmable gate array (FPGA) designs. The majority of the book assumes a basic background in logic design and software programming concepts. It is directed at: * students currently in an introductory logic design course that also teaches SystemVerilog, * designers who want to update their skills from Verilog or VHDL, and * students in VLSI design and advanced logic design courses that include verification as well as design topics. The book starts with a tutorial introduction on hardware description languages and simulation. It proceeds to the register-transfer design topics of combinational and finite state machine (FSM) design - these mirror the topics of introductory logic design courses. The book covers the design of FSM-datapath designs and their interfaces, including SystemVerilog interfaces. Then it covers the more advanced topics of writing testbenches including using assertions and functional coverage. A comprehensive index provides easy access to the book's topics.The goal of the book is to introduce the broad spectrum of features in the language in a way that complements introductory and advanced logic design and verification courses, and then provides a basis for further learning.Solutions to problems at the end of chapters, and text copies of the SystemVerilog examples are available from the author as described in the Preface. |
| functional verification basics: The e Hardware Verification Language Sasan Iman, Sunita Joshi, 2004-05-28 I am glad to see this new book on the e language and on verification. I am especially glad to see a description of the e Reuse Methodology (eRM). The main goal of verification is, after all, finding more bugs quicker using given resources, and verification reuse (module-to-system, old-system-to-new-system etc. ) is a key enabling component. This book offers a fresh approach in teaching the e hardware verification language within the context of coverage driven verification methodology. I hope it will help the reader und- stand the many important and interesting topics surrounding hardware verification. Yoav Hollander Founder and CTO, Verisity Inc. Preface This book provides a detailed coverage of the e hardware verification language (HVL), state of the art verification methodologies, and the use of e HVL as a facilitating verification tool in implementing a state of the art verification environment. It includes comprehensive descriptions of the new concepts introduced by the e language, e language syntax, and its as- ciated semantics. This book also describes the architectural views and requirements of verifi- tion environments (randomly generated environments, coverage driven verification environments, etc. ), verification blocks in the architectural views (i. e. generators, initiators, c- lectors, checkers, monitors, coverage definitions, etc. ) and their implementations using the e HVL. Moreover, the e Reuse Methodology (eRM), the motivation for defining such a gui- line, and step-by-step instructions for building an eRM compliant e Verification Component (eVC) are also discussed. |

| functional verification basics: Verification, Validation, and Testing of Engineered Systems Avner Engel, 2010-11-19 Systems' Verification Validation and Testing (VVT) are carried out throughout systems' lifetimes. Notably, quality-cost expended on performing VVT activities and correcting system defects consumes about half of the overall engineering cost. Verification, Validation and Testing of Engineered Systems provides a comprehensive compendium of VVT activities and corresponding VVT methods for implementation throughout the entire lifecycle of an engineered system. In addition, the book strives to alleviate the fundamental testing conundrum, namely: What should be tested? How should one test? When should one test? And, when should one stop testing? In other words, how should one select a VVT strategy and how it be optimized? The book is organized in three parts: The first part provides introductory material about systems and VVT concepts. This part presents a comprehensive explanation of the role of VVT in the process of engineered systems (Chapter-1). The second part describes 40 systems' development VVT activities (Chapter-2) and 27 systems' post-development activities (Chapter-3). Corresponding to these activities, this part also describes 17 non-testing systems' VVT methods (Chapter-4) and 33 testing systems' methods (Chapter-5). The third part of the book describes ways to model systems' quality cost, time and risk (Chapter-6), as well as ways to acquire quality data and optimize the VVT strategy in the face of funding, time and other resource limitations as well as different business objectives (Chapter-7). Finally, this part describes the methodology used to validate the quality model along with a case study describing a system's quality improvements (Chapter-8). Fundamentally, this book is written with two categories of audience in mind. The first category is composed of VVT practitioners, including Systems, Test, Production and Maintenance engineers as well as first and second line managers. The second category is composed of students and faculties of Systems, Electrical, Aerospace, Mechanical and Industrial Engineering schools. This book may be fully covered in two to three graduate level semesters; although parts of the book may be covered in one semester. University instructors will most likely use the book to provide engineering students with knowledge about VVT, as well as to give students an introduction to formal modeling and optimization of VVT strategy. |

| functional verification basics: Rtl Modeling With Systemverilog for Simulation and Synthesis Stuart Sutherland, 2017-06-10 This book is both a tutorial and a reference for engineers who use the SystemVerilog Hardware Description Language (HDL) to design ASICs and FPGAs. The book shows how to write SystemVerilog models at the Register Transfer Level (RTL) that simulate and synthesize correctly, with a focus on proper coding styles and best practices. SystemVerilog is the latest generation of the original Verilog language, and adds many important capabilities to efficiently and more accurately model increasingly complex designs. This book reflects the SystemVerilog-2012/2017 standards. This book is for engineers who already know, or who are learning, digital design engineering. The book does not present digital design theory; it shows how to apply that theory to write RTL models that simulate and synthesize correctly. The creator of the original Verilog Language, Phil Moorby says about this book (an excerpt from the book's Foreword): Many published textbooks on the design side of SystemVerilog assume that the reader is familiar with Verilog, and simply explain the new extensions. It is time to leave behind the stepping-stones and to teach a single consistent and concise language in a single book, and maybe not even refer to the old ways at all! If you are a designer of digital systems, or a verification engineer searching for bugs in these designs, then SystemVerilog will provide you with significant benefits, and this book is a great place to learn the design aspects of SystemVerilog. |
| functional verification basics: System Design with SystemC™ Thorsten Grötker, 2002-05-31 The emergence of the system-on-chip (SoC) era is creating many new challenges at all stages of the design process. Engineers are reconsidering how designs are specified, partitioned and verified. With systems and software engineers programming in C/C++ and their hardware counterparts working in hardware description languages such as VHDL and Verilog, problems arise from the use of different design languages, incompatible tools and fragmented tool flows. Momentum is building behind the SystemC language and modeling platform as the best solution for representing functionality, communication, and software and hardware implementations at various levels of abstraction. The reason is clear: increasing design complexity demands very fast executable specifications to validate system concepts, and only C/C++ delivers adequate levels of abstraction, hardware-software integration, and performance. System design today also demands a single common language and modeling foundation in order to make interoperable system--level design tools, services and intellectual property a reality. SystemC is entirely based on C/C++ and the complete source code for the SystemC reference simulator can be freely downloaded from www.systemc.org and executed on both PCs and workstations. System Design and SystemC provides a comprehensive introduction to the powerful modeling capabilities of the SystemC language, and also provides a large and valuable set of system level modeling examples and techniques. Written by experts from Cadence Design Systems, Inc. and Synopsys, Inc. who were deeply involved in the definition and implementation of the SystemC language and reference simulator, this book will provide you with the key concepts you need to be successful with SystemC. System Design with SystemC thoroughly covers the new system level modeling capabilities available in SystemC 2.0 as well as the hardware modeling capabilities available in earlier versions of SystemC. designed and implemented the SystemC language and reference simulator, this book will provide you with the key concepts you need to be successful with SystemC. System Design with SystemC will be of interest to designers in industry working on complex system designs, as well as students and researchers within academia. All of the examples and techniques described within this book can be used with freely available compilers and debuggers – no commercial software is needed. Instructions for obtaining the free source code for the examples obtained within this book are included in the first chapter. |
