“The purpose of this book is to provide students and young engineers with a guide to help them develop the skills necessary to be able to use VHDL for introductory and intermediate level digital design. These skills will also give you the ability and the confidence to continue on with VHDL-based digital design. In this way, you will also take steps toward developing the skills required to implement more advanced digital design systems. Although there are many books and on-line tutorials dealing with VHDL, these sources are often troublesome for several reasons. Firstly, much of the information regarding VHDL is either needlessly confusing or poorly written. Material with these characteristics seems to be written from the standpoint of someone who is either painfully intelligent or has forgotten that their audience may be seeing the material for the first time. Secondly, the common approach for most VHDL manuals is to introduce too many topics and a lot of extraneous information too early. Most of this material would best appear later in the presentation. Material presented in this manner has a tendency to be confusing, is easily forgotten if misunderstood or simply is never applied. The approach taken by this book is to provide only what you need to know to quickly get up and running in VHDL. As with all learning, once you have obtained and applied some useful information, it is much easier to build on what you know as opposed to continually adding information that is not directly applicable to the subjects at hand.”
