Vhdl Answers To Frequently Asked Questions

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.

VHDL Coding Styles and Methodologies, Edition is a follow up book to the first edition of same book and to VHDL Answers to Frequently Asked Questions, first and second editions. This book 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 edition provides practical information on reusable software methodologies for the design of bus functional models for testbenches. It also provides guidelines in the use of VHDL for synthesis. All VHDL code described in the book is on a companion CD. The CD also includes the GNU toolsuite with EMACS language sensitive editor (with VHDL, Verilog, and other language templates), and TSHELL tools that emulate a Unix shell. Model Technology graciously included a timed evaluation version of ModelSim, a recognized industry standard VHDL/Verilog compiler and simulator that supports easy viewing of the models under analysis, along with many debug features. In addition, Synplicity included a timed version of Synplify, a very efficient, user friendly and easy to use FPGA synthesis tool. Synplify provides a user both the RTL and gate level views of the synthesized model, and a performance report of the design. Optimization mechanisms are provided in the tool.

Although not evident to all, many people have been waiting more than a decade for The SGML FAQ Book by Steve DeRose. It has been "brewing" for a long time, with many hours, months, years of research talking to people, gathering their ideas, listening to their frustrations, applauding their successes. Only Steve with his experience, credentials, wit, and enthusiasm for the subject could have written this book. But it is also a measure of the success and maturity of ISO 8879 and its amazing longevity that allows an "SGMLer" to write such a book. We can now laugh at ourselves, even disclose our mistakes without fear of the other guy. While most would not recognize it, the revolution known as the World Wide Web would not have happened without a non-proprietary, easy, and almost "portable way to create and distribute documents across a widely disparate set of computers, networks, even countries. HTML, an SGML application, enabled this and as a result the world and the SGML community will never be the same. For some the term SGML means order, management, standards, discipline; to others, the term brings images of pain, confusion, complexity, and pitfalls. To all who have engaged in it, the Standard means hard work, good friends, savings in terms of time, money, and effort, a sense of accomplishment and best of all - fun. This book adds immeasurably to all of these. Enjoy the quote from Through Looking by Lewis Carroll as much as we have.

This book concentrates on common classes of hardware architectures and design problems, and focuses on the process of transitioning design requirements into synthesizable HDL code. Using his extensive, wide-ranging experience in computer architecture and hardware design, as well as in his training and consulting work, Ben provides numerous examples of real-life designs illustrated with VHDL and Verilog code. This code is shown in a way that makes it easy for the reader to gain a greater understanding of the languages and how they compare. All code presented in the book is included on the companion CD, along with other information, such as application notes.

This practical, tool-independent guide to designing digital circuits takes a unique, top-down approach, reflecting the nature of the design process in industry. Starting with architecture design, the book comprehensively explains the why and how of digital circuit design, using the physics designers need to know, and no more.
