Book excerpt: 2 Concept ( Tools • Specification ( Tools + Design Stages ( Tools • Implementation ( Tools Figure 1-1. A nominal, multi-stage development process From that beginning, we have progressed to the point where the EDA community at large, including both users and developers of the tools, are interested in more unified environments. Here, the notion is that the tools used at the various stages in the development process need to be able to complement each other, and to communicate with one another efficiently using effective file exchange capabilities. Furthermore, the idea of capturing all the tool support needed for an EDA development into a unified support environment is now becoming a reality. This reality is evidenced by some of the EDA suites we now see emerging, wherein several tool functions are integrated under a common graphical user interface (GUI), with supporting file exchange and libraries to enable all tool functions to operate effectively and synergistically. This concept, which we illustrate in Figure 1- 2, is the true future ofEDA.

Download or read book Waves VHDL Interface written by and published by . This book was released on 1994 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Waveform and Vector Exchange Specification (WAVES) is the Industry standard representation for digital stimulus and response for both the design and test communities. The VHSIC Hardware Description Language (VHDL) is the Industry standard language for the design, modeling, and simulation of digital electronics. Together VHDL and WAVES provide powerful support for top-down design and test methodologies and concurrent engineering practices. Although the syntax of WAVES is a subset of VHDL, no special support for using WAVES in a VHDL environment is defined within the language. This report will introduce and describe a VHDL package that was developed at Rome Laboratory to provide a software interface to support the use of WAVES in a VHDL environment. This VHDL package is referred to as the WAVES VHDL interface and has been proposed as a standard practice for a top-down design and test methodology using WAVES and VHDL. This report is not intended to provide a tutorial on VHDL or WAVES. It is assumed that the reader has an adequate understanding of the VHDL language and some modeling techniques. Further, it is assumed that the reader has an understanding of the WAVES language and can follow a simple Level 1 dataset description.

Download or read book VHDL for Simulation Synthesis and Formal Proofs of Hardware written by Jean Mermet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of VHDL since it has been balloted in 1987 as an IEEE standard may look incomprehensible to the large population of hardware designers, who had never heared of Hardware Description Languages before (for at least 90% of them), as well as to the few hundreds of specialists who had been working on these languages for a long time (25 years for some of them). Until 1988, only a very small subset of designers, in a few large companies, were used to describe their designs using a proprietary HDL, or sometimes a HDL inherited from a University when some software environment happened to be developped around it, allowing usability by third parties. A number of benefits were definitely recognized to this practice, such as functional verification of a specification through simulation, first performance evaluation of a tentative design, and sometimes automatic microprogram generation or even automatic high level synthesis. As there was apparently no market for HDL's, the ECAD vendors did not care about them, start-up companies were seldom able to survive in this area, and large users of proprietary tools were spending more and more people and money just to maintain their internal system.

Download or read book VHDL and Waves Descriptions for a Pseudo Random Pattern Generator written by and published by . This book was released on 1992 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A VHDL model for a 32-bit linear feedback shift register is documented, along with a WAVES dataset that provides test vectors for it. The register operates with a leading-edge dual clock, an asynchronous reset, and control bits to enable shifting (to the right) and loading. Other inputs are a polynomial and a seed value; the output is a bit pattern. The feedback feature is controller by the polynomial. For each polynomial bit position with a value of '1', the value of the register corresponding to that is fed through feedback before being shifted. The WAVES dataset is used to generate input test vectors for the register, and to provide a utility to compare actual outputs to predicted outputs. There are three different architectures for the register: structural behavioral, and structural with multiple component instantiations produced by the VHDL generate statement. There are also two architectures for the test bench: one that uses the WAVES dataset, and one that produces input vectors internally. The WAVES test bench uses a built-in utility to check outputs from each of the three register architectures against each other, and the non-WAVES test bench does these checks internally.

Download or read book The Designer s Guide to VHDL written by Peter J. Ashenden and published by Elsevier. This book was released on 2001-06-05 with total page 791 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition of The Designer's Guide to VHDL in 1996, digital electronic systems have increased exponentially in their complexity, product lifetimes have dramatically shrunk, and reliability requirements have shot through the roof. As a result more and more designers have turned to VHDL to help them dramatically improve productivity as well as the quality of their designs. VHDL, the IEEE standard hardware description language for describing digital electronic systems, allows engineers to describe the structure and specify the function of a digital system as well as simulate and test it before manufacturing. In addition, designers use VHDL to synthesize a more detailed structure of the design, freeing them to concentrate on more strategic design decisions and reduce time to market. Adopted by designers around the world, the VHDL family of standards have recently been revised to address a range of issues, including portability across synthesis tools. This best-selling comprehensive tutorial for the language and authoritative reference on its use in hardware design at all levels--from system to gates--has been revised to reflect the new IEEE standard, VHDL-2001. Peter Ashenden, a member of the IEEE VHDL standards committee, presents the entire description language and builds a modeling methodology based on successful software engineering techniques. Reviewers on Amazon.com have consistently rated the first edition with five stars. This second edition updates the first, retaining the authors unique ability to teach this complex subject to a broad audience of students and practicing professionals.* Details how the new standard allows for increased portability across tools.* Covers related standards, including the Numeric Synthesis Package and the Synthesis Operability Package, demonstrating how they can be used for digital systems design.* Presents four extensive case studies to demonstrate and combine features of the language taught across multiple chapters.* Requires only a minimal background in programming, making it an excellent tutorial for anyone in computer architecture, digital systems engineering, or CAD.

Download or read book VHDL Coding Styles and Methodologies written by Ben Cohen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: VHDL Coding Styles and Methodologies was originally written as a teaching tool for a VHDL training course. The author began writing the book because he could not find a practical and easy to read book that gave in depth coverage of both, the language and coding methodologies. This book is intended for: 1. College students. It is organized in 13 chapters, each covering a separate aspect of the language, with complete examples. All VHDL code described in the book is on a companion 3.5" PC disk. Students can compile and simulate the examples to get a greater understanding of the language. Each chapter includes a series of exercises to reinforce the concepts. 2. Engineers. It is written by an aerospace engineer who has 26 years of hardware, software, computer architecture and simulation experience. It covers practical applications ofVHDL with coding styles and methodologies that represent what is current in the industry. VHDL synthesizable constructs are identified. Guidelines for testbench designs are provided. Also included is a project for the design of a synthesizable Universal Asynchronous Receiver Transmitter (UART), and a testbench to verify proper operation of the UART in a realistic environment, with CPU interfaces and transmission line jitter. An introduction to VHDL Initiative Toward ASIC Libraries (VITAL) is also provided. The book emphasizes VHDL 1987 standard but provides guidelines for features implemented in VHDL 1993.

Download or read book A Designer s Guide to VHDL Synthesis written by Douglas E. Ott and published by Springer. This book was released on 2013-12-19 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Designer's Guide to VHDL Synthesis is intended for both design engineers who want to use VHDL-based logic synthesis ASICs and for managers who need to gain a practical understanding of the issues involved in using this technology. The emphasis is placed more on practical applications of VHDL and synthesis based on actual experiences, rather than on a more theoretical approach to the language. VHDL and logic synthesis tools provide very powerful capabilities for ASIC design, but are also very complex and represent a radical departure from traditional design methods. This situation has made it difficult to get started in using this technology for both designers and management, since a major learning effort and `culture' change is required. A Designer's Guide to VHDL Synthesis has been written to help design engineers and other professionals successfully make the transition to a design methodology based on VHDL and log synthesis instead of the more traditional schematic based approach. While there are a number of texts on the VHDL language and its use in simulation, little has been written from a designer's viewpoint on how to use VHDL and logic synthesis to design real ASIC systems. The material in this book is based on experience gained in successfully using these techniques for ASIC design and relies heavily on realistic examples to demonstrate the principles involved.

Download or read book Synthesizable VHDL Design for FPGAs written by Eduardo Augusto Bezerra and published by Springer Science & Business Media. This book was released on 2013-10-21 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The methodology described in this book is the result of many years of research experience in the field of synthesizable VHDL design targeting FPGA based platforms. VHDL was first conceived as a documentation language for ASIC designs. Afterwards, the language was used for the behavioral simulation of ASICs, and also as a design input for synthesis tools. VHDL is a rich language, but just a small subset of it can be used to write synthesizable code, from which a physical circuit can be obtained. Usually VHDL books describe both, synthesis and simulation aspects of the language, but in this book the reader is conducted just through the features acceptable by synthesis tools. The book introduces the subjects in a gradual and concise way, providing just enough information for the reader to develop their synthesizable digital systems in VHDL. The examples in the book were planned targeting an FPGA platform widely used around the world.

Download or read book VHDL Answers to Frequently Asked Questions written by Ben Cohen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: VHDL Answers to Frequently asked Questions is a follow-up to the author's book VHDL Coding Styles and Methodologies (ISBN 0-7923-9598-0). On completion of his first book, the author continued teaching VHDL and actively participated in the comp. lang. vhdl newsgroup. During his experiences, he was enlightened by the many interesting issues and questions relating to VHDL and synthesis. These pertained to: misinterpretations in the use of the language; methods for writing error free, and simulation efficient, code for testbench designs and for synthesis; and general principles and guidelines for design verification. As a result of this wealth of public knowledge contributed by a large VHDL community, the author decided to act as a facilitator of this information by collecting different classes of VHDL issues, and by elaborating on these topics through complete simulatable examples. TItis book is intended for those who are seeking an enhanced proficiency in VHDL. Its target audience includes: 1. Engineers. The book addresses a set of problems commonly experienced by real users of VHDL. It provides practical explanations to the questions, and suggests practical solutions to the raised issues. It also includes packages of common utilities that are useful in the generation of debug code and testbench designs. These packages include conversions to strings (the IMAGE package), generation of Linear Feedback Shift Registers (LFSR), Multiple Input Shift Register (MISR), and random number generators.

Download or read book RTL Hardware Design Using VHDL written by Pong P. Chu and published by John Wiley & Sons. This book was released on 2006-04-20 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: The skills and guidance needed to master RTL hardware design This book teaches readers how to systematically design efficient, portable, and scalable Register Transfer Level (RTL) digital circuits using the VHDL hardware description language and synthesis software. Focusing on the module-level design, which is composed of functional units, routing circuit, and storage, the book illustrates the relationship between the VHDL constructs and the underlying hardware components, and shows how to develop codes that faithfully reflect the module-level design and can be synthesized into efficient gate-level implementation. Several unique features distinguish the book: * Coding style that shows a clear relationship between VHDL constructs and hardware components * Conceptual diagrams that illustrate the realization of VHDL codes * Emphasis on the code reuse * Practical examples that demonstrate and reinforce design concepts, procedures, and techniques * Two chapters on realizing sequential algorithms in hardware * Two chapters on scalable and parameterized designs and coding * One chapter covering the synchronization and interface between multiple clock domains Although the focus of the book is RTL synthesis, it also examines the synthesis task from the perspective of the overall development process. Readers learn good design practices and guidelines to ensure that an RTL design can accommodate future simulation, verification, and testing needs, and can be easily incorporated into a larger system or reused. Discussion is independent of technology and can be applied to both ASIC and FPGA devices. With a balanced presentation of fundamentals and practical examples, this is an excellent textbook for upper-level undergraduate or graduate courses in advanced digital logic. Engineers who need to make effective use of today's synthesis software and FPGA devices should also refer to this book.
