Connect with: Attributes and Groups Generate Statements I am grateful to the many engineers, stu- dents and teachers around the world who gave me the impetus to write these books and who made them such a success.

Thanks also to Mentor Graphics Cor- xxii Preface poration for continued use of the ModelSim simulator to check the example code. I con- tinue to enjoy an excellent working relationship with the staff at Morgan Kaufmann Publishers and their parent company, Elsevier.

I remain deeply grateful for her continued sup- port and am honored to also dedicate this third edition to her. We see how the hardware description language VHDL can be used to model digital systems and intro- duce some of the basic concepts underlying the language. We complete this chapter with a description of the basic lexical and syntactic elements of the language, to form a basis for the detailed descriptions of language features that follow in later chapters. Different engineers would come up with different definitions, depend- ing on their background and the field in which they were working.

Some may consider a single VLSI circuit to be a self-contained digital system. Others might take a larger view and think of a complete computer, packaged in a cabinet with peripheral controllers and other interfaces. For the purposes of this book, we include any digital circuit that processes or stores information as a digital system. We thus consider both the system as a whole and the var- ious parts from which it is constructed.

Therefore, our discussions cover a range of systems from the low-level gates that make up the components to the top-level functional units. If we are to encompass this range of views of digital systems, we must recognize the complexity with which we are dealing.

It is not humanly possible to comprehend such complex systems in their entirety. We need to find methods of dealing with the complex- ity, so that we can, with some degree of confidence, design components and systems that meet their requirements. The most important way of meeting this challenge is to adopt a systematic methodol- ogy of design. If we start with a requirements document for the system, we can design an abstract structure that meets the requirements.

We can then decompose this structure into a collection of components that interact to perform the same function. Each of these com- ponents can in turn be decomposed until we get to a level where we have some ready- made, primitive components that perform a required function. The result of this process is a hierarchically composed system, built from the primitive elements.

When we use a subsystem, we can think of it as an abstraction rather than having to consider its detailed composition. So at any particular stage in the design process, we only need to pay attention to the small amount of information relevant to the current focus of design. We are saved from being overwhelmed by masses of detail. We use the term model to mean our understanding of a system.

The model represents that information which is relevant and abstracts away from irrelevant detail. The implica- tion of this is that there may be several models of the same system, since different infor- mation is relevant in different contexts.
