"VHDL Programming by Example 是 Douglas L. Perry 撰写的一本经典国外教程，由 McGraw-Hill 出版社发行。本书是第四版，旨在通过实例帮助读者掌握 VHDL 编程技术。" 在电子设计自动化（EDA）领域，VHDL（Very High Speed Integrated Circuit Hardware Description Language）是一种重要的硬件描述语言，用于设计、验证和模拟数字系统。《VHDL Programming by Example》这本书深入浅出地介绍了VHDL的基础和高级概念，适合初学者和有经验的工程师阅读。书中可能包含以下关键知识点： 1. **VHDL基础知识**：包括VHDL的数据类型（如std_logic和std_logic_vector）、实体（Entity）、结构体（Architecture）、进程（Process）以及各种运算符的使用。 2. **VHDL设计模式**：书中可能涵盖常见的设计模式，如组合逻辑电路、时序逻辑电路、状态机、多路复用器、存储器等的设计方法。 3. **VHDL仿真与综合**：介绍如何使用VHDL进行设计验证，包括编写测试平台（Testbench）以及如何将VHDL代码转换成可实现的逻辑门级电路（Synthesis）。 4. **高级特性**：可能涉及VHDL的包（Package）、子程序（Subprogram）、库（Library）、保护类型（Protected Type）等高级特性，以及库导入和实体/架构的重用策略。 5. **实例分析**：通过实际案例来解释和演示VHDL的使用，帮助读者理解抽象到具体实现的过程，提升设计能力。 6. **设计流程**：涵盖从概念设计、逻辑设计、仿真验证、物理布局到布线的完整流程，以及如何在不同的EDA工具（如ModelSim、Synopsys、Altera Quartus或Xilinx ISE）中应用VHDL。 7. **错误处理和调试技巧**：讲解如何识别和解决VHDL设计中的常见问题，以及如何使用VHDL进行有效的调试。 8. **IP核（ Intellectual Property Core）**：介绍如何创建和使用VHDL定义的可重用IP核，以提高设计效率。 9. **数字系统设计原理**：结合VHDL讲解数字逻辑基础，如布尔代数、时序逻辑、并行和串行数据处理等。 10. **行业标准与规范**：可能涉及IEEE 1076标准更新，以及VHDL在不同领域的应用规范。这本书对于想要学习和提升VHDL编程技能的人来说是一份宝贵的资源，不仅可以提供理论知识，还强调实践操作，使读者能够通过实例学习到实际的设计技巧和最佳实践。

PREFACE

This is the fourth version of the book and this version now not only provides

VHDL language coverage but design methodology information as well. This

version will guide the reader through the process of creating a VHDL

design, simulating the design, synthesizing the design, placing and routing

the design, using VITAL simulation to verify the final result, and a new

technique called At-Speed debugging that provides extremely fast design

verification. The design example in this version has been updated to reflect

the new focus on the design methodology.

This book was written to help hardware design engineers learn how to

write good VHDL design descriptions. The goal is to provide enough VHDL

and design methodology information to enable a designer to quickly write

good VHDL designs and be able to verify the results. It will also attempt

to bring the designer with little or no knowledge of VHDL, to the level of

writing complex VHDL descriptions. It is not intended to show every pos-

sible construct of VHDL in every possible use, but rather to show the de-

signer how to write concise, efficient, and correct VHDL descriptions of

hardware designs.

This book is organized into three logical sections. The first section of the

book will introduce the VHDL language, the second section walks through

a VHDL based design process including simulation, synthesis, place and

route, and VITAL simulation; and the third section walks through a design

example of a small CPU design from VHDL capture to final gate-level

implementation, and At-Speed debugging. At the back of the book are

included a number of appendices that contain useful information about the

language and examples used throughout the book.

In the first section VHDL features are introduced one or more at a time.

As each feature is introduced, one or more real examples are given to show

how the feature would be used. The first section consists of Chapters 1

through 8, and each chapter introduces a basic description capability of

VHDL. Chapter 1 discusses how VHDL design relates to schematic based

design, and introduces the basic terms of the language. Chapter 2 describes

some of the basic concepts of VHDL, including the different delay mecha-

nisms available, how to use instance specific data, and defines VHDL dri-

vers. Chapter 2 discusses concurrent statements while Chapter 3 introduces

the reader to VHDL sequential statements. Chapter 4 talks about the wide

range of types available for use in VHDL. Examples are given for each of

the types showing how they would be used in a real example. In Chapter

5 the concepts of subprograms and packages are introduced. The different

uses for functions are given, as well as the features available in VHDL

packages.

Chapter 6 introduces the five kinds of VHDL attributes. Each attribute

kind has examples describing how to use the specific attribute to the

designer’s best advantage. Examples are given which describe the pur-

pose of each of the attributes.

Chapters 7 and 8 will introduce some of the more advanced VHDL

features to the reader. Chapter 7 discusses how VHDL configurations

can be used to construct and manage complex VHDL designs. Each of

the different configuration styles are discussed along with examples

showing usage. Chapter 8 introduces more of the VHDL advanced top-

ics with discussions of overloading, user defined attributes, generate

statements, and TextIO.

The second section of the book consists of Chapters 9 through 11. Chap-

ters 9 and 10 discuss the synthesis process and how to write synthesiz-

able designs. These two chapters describe the basics of the synthesis

process including how to write synthesizeable VHDL, what is a technol-

ogy library, what does the synthesis process look like, what are con-

straints and attributes, and what does the the optimization process look

like. Chapter 11 discusses the complete high level design flow from VHDL

capture through VITAL simulation.

The third section of the book walks through a description of a small

CPU design from the VHDL capture through simulation, synthesis, place

and route, and VITAL simulation. Chapter 12 describes the top level of

the CPU design from a functional point of view. In Chapter 13 the RTL

description of the CPU is presented and discussed from a synthesis point

of view. Chapter 14 begins with a discussion of VHDL testbenches and

how they are used to verify functionality. Chapter 14 finishes the discus-

sion by describing the simulation of the CPU design. In Chapter 15 the

verified design is synthesized to a target technology. Chapter 16 takes

the synthesized design and places and routes the design to a target

device. Chapter 17 begins with a discussion of VITAL and ends with the

VITAL simulation of the placed and routed CPU design. Chapter 18 is a

new chapter that discusses the new technique of At-Speed debugging.

This chapter provides the reader with an in-depth look at how a hardware

implementation of the CPU design can help speed verification.

Finally there are three appendices at the end of the book to provide ref-

erence information. Appendix A is a listing of the IEEE 1164 STD_LOGIC
