| flip flop code in verilog: Verilog and SystemVerilog Gotchas Stuart Sutherland, Don Mills, 2010-04-30 In programming, “Gotcha” is a well known term. A gotcha is a language feature, which, if misused, causes unexpected - and, in hardware design, potentially disastrous - behavior. The purpose of this book is to enable engineers to write better Verilog/SystemVerilog design and verification code, and to deliver digital designs to market more quickly. This book shows over 100 common coding mistakes that can be made with the Verilog and SystemVerilog languages. Each example explains in detail the symptoms of the error, the languages rules that cover the error, and the correct coding style to avoid the error. The book helps digital design and verification engineers to recognize these common coding mistakes, and know how to avoid them. Many of these errors are very subtle, and can potentially cost hours or days of lost engineering time trying to find and debug the errors. This book is unique because while there are many books that teach the language, and a few that try to teach coding style, no other book addresses how to recognize and avoid coding errors with these languages. |

| flip flop code in verilog: Verilog: Frequently Asked Questions Shivakumar S. Chonnad, Needamangalam B. Balachander, 2007-05-08 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. |

| flip flop code in verilog: Writing Testbenches using SystemVerilog Janick Bergeron, 2007-02-02 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. |

| flip flop code in verilog: Digital System Test and Testable Design Zainalabedin Navabi, 2010-12-10 This book is about digital system testing and testable design. The concepts of testing and testability are treated together with digital design practices and methodologies. The book uses Verilog models and testbenches for implementing and explaining fault simulation and test generation algorithms. Extensive use of Verilog and Verilog PLI for test applications is what distinguishes this book from other test and testability books. Verilog eliminates ambiguities in test algorithms and BIST and DFT hardware architectures, and it clearly describes the architecture of the testability hardware and its test sessions. Describing many of the on-chip decompression algorithms in Verilog helps to evaluate these algorithms in terms of hardware overhead and timing, and thus feasibility of using them for System-on-Chip designs. Extensive use of testbenches and testbench development techniques is another unique feature of this book. Using PLI in developing testbenches and virtual testers provides a powerful programming tool, interfaced with hardware described in Verilog. This mixed hardware/software environment facilitates description of complex test programs and test strategies. |
| flip flop code in verilog: 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). |

| flip flop code in verilog: SystemVerilog for Design Second Edition Stuart Sutherland, Simon Davidmann, Peter Flake, 2006-09-15 SystemVerilog is a rich set of extensions to the IEEE 1364-2001 Verilog Hardware Description Language (Verilog HDL). These extensions address two major aspects of HDL-based design. First, modeling very large designs with concise, accurate, and intuitive code. Second, writing high-level test programs to efficiently and effectively verify these large designs. The first edition of this book addressed the first aspect of the SystemVerilog extensions to Verilog. Important modeling features were presented, such as two-state data types, enumerated types, user-degined types, structures, unions, and interfaces. Emphasis was placed on the proper usage of these enhancements for simulation and synthesis. SystemVerilog for Design, Second Edition has been extensively revised on a chapter by chapter basis to include the many text and example updates needed to reflect changes that were made between the first edition of this book was written and the finalization of the new standard. It is important that the book reflect these syntax and semantic changes to the SystemVerilog language. In addition, the second edition features a new chapter that explanis the SystemVerilog packages, a new appendix that summarizes the synthesis guidelines presented throughout the book, and all of the code examples have been updated to the final syntax and rerun using the latest version of the Synopsys, Mentor, and Cadance tools. |
| flip flop code in verilog: Applied Digital Logic Exercises Using FPGAs Kurt Wick, 2017-10-03 FPGAs have almost entirely replaced the traditional Application Specific Standard Parts (ASSP) such as the 74xx logic chip families because of their superior size, versatility, and speed. For example, FPGAs provide over a million fold increase in gates compared to ASSP parts. The traditional approach for hands-on exercises has relied on ASSP parts, primarily because of their simplicity and ease of use for the novice. Not only is this approach technically outdated, but it also severely limits the complexity of the designs that can be implemented. By introducing the readers to FPGAs, they are being familiarized with current digital technology and the skills to implement complex, sophisticated designs. However, working with FGPAs comes at a cost of increased complexity, notably the mastering of an HDL language, such as Verilog. Therefore, this book accomplishes the following: first, it teaches basic digital design concepts and then applies them through exercises; second, it implements these digital designs by teaching the user the syntax of the Verilog language while implementing the exercises. Finally, it employs contemporary digital hardware, such as the FPGA, to build a simple calculator, a basic music player, a frequency and period counter and it ends with a microprocessor being embedded in the fabric of the FGPA to communicate with the PC. In the process, readers learn about digital mathematics and digital-to-analog converter concepts through pulse width modulation. |

| flip flop code in verilog: Digital Design and Implementation with Field Programmable Devices Zainalabedin Navabi, 2006-02-28 This book is on digital system design for programmable devices, such as FPGAs, CPLDs, and PALs. A designer wanting to design with programmable devices must understand digital system design at the RT (Register Transfer) level, circuitry and programming of programmable devices, digital design methodologies, use of hardware description languages in design, design tools and environments; and finally, such a designer must be familiar with one or several digital design tools and environments. Books on these topics are many, and they cover individual design topics with very general approaches. The number of books a designer needs to gather the necessary information for a practical knowledge of design with field programmable devices can easily reach five or six, much of which is on theoretical concepts that are not directly applicable to RT level design with programmable devices. The focus of this book is on a practical knowledge of digital system design for programmable devices. The book covers all necessary topics under one cover, and covers each topic just enough that is actually used by an advanced digital designer. In the three parts of the book, we cover digital system design concepts, use of tools, and systematic design of digital systems. In the first chapter, design methodologies, use of simulation and synthesis tools and programming programmable devices are discussed. Based on this automated design methodology, the next four chapters present the necessary background for logic design, the Verilog language, programmable devices, and computer architectures. |

| flip flop code in verilog: Higher-Level Hardware Synthesis Richard Sharp, 2004-03-18 In the mid 1960s, when a single chip contained an average of 50 transistors, Gordon Moore observed that integrated circuits were doubling in complexity every year. In an in?uential article published by Electronics Magazine in 1965, Moore predicted that this trend would continue for the next 10 years. Despite being criticized for its “unrealistic optimism,” Moore’s prediction has remained valid for far longer than even he imagined: today, chips built using state-- the-art techniques typically contain several million transistors. The advances in fabrication technology that have supported Moore’s law for four decades have fuelled the computer revolution. However,this exponential increase in transistor density poses new design challenges to engineers and computer scientists alike. New techniques for managing complexity must be developed if circuits are to take full advantage of the vast numbers of transistors available. In this monograph we investigate both (i) the design of high-level languages for hardware description, and (ii) techniques involved in translating these hi- level languages to silicon. We propose SAFL, a ?rst-order functional language designedspeci?callyforbehavioralhardwaredescription,anddescribetheimp- mentation of its associated silicon compiler. We show that the high-level pr- erties of SAFL allow one to exploit program analyses and optimizations that are not employed in existing synthesis systems. Furthermore, since SAFL fully abstracts the low-leveldetails of the implementation technology, we show how it can be compiled to a range of di?erent design styles including fully synchronous design and globally asynchronous locally synchronous (GALS) circuits. |

| flip flop code in verilog: Pragmatic Logic William J. Eccles, 2022-05-31 Pragmatic Logic presents the analysis and design of digital logic systems. The author begins with a brief study of binary and hexadecimal number systems and then looks at the basics of Boolean algebra. The study of logic circuits is divided into two parts, combinational logic, which has no memory, and sequential logic, which does. Numerous examples highlight the principles being presented. The text ends with an introduction to digital logic design using Verilog, a hardware description language. The chapter on Verilog can be studied along with the other chapters in the text. After the reader has completed combinational logic in Chapters 4 and 5, sections 9.1 and 9.2 would be appropriate. Similarly, the rest of Chapter 9 could be studied after completing sequential logic in Chapters 6 and 7. This short lecture book will be of use to students at any level of electrical or computer engineering and for practicing engineers or scientists in any field looking for a practical and applied introduction to digital logic. The author's pragmatic and applied style gives a unique and helpful non-idealist, practical, opinionated introduction to digital systems. |
