This text presents the IEEE 1364-2001 standard of the Verilog language. The examples in this edition have been updated to illustrate the features of the language. A cross referenced guide to these features is provided, thus, designers already familiar with Verilog can quickly learn the features. Newcomers to the language can use it as a guide for reading "old" specifications. The book should prove to be a useful resource for engineers and students interested in describing, simulating and synthesizing digital systems. It is also ready for use in university courses, having been used for introductory logic design and simulation through advanced VLSI design courses. An appendix with tutorial help and a work-along style is keyed into the introduction for new students. Material supporting a computer-aided design course on the inner working of simulators is also included. "The Verilog TM Hardware Description Language" includes a CD containing Simucad's Silos TM 2001 Verilog Simulator, examples from the book and lecture slides. The simulator is limited in the size of descriptions it will simulate. A few of the language constructs are not recognized by this version of the simulator.

The Verilog language is a hardware description language which provides a means of specifying a digital system at a wide range of levels of abstraction. The language supports the early conceptual stages of design with its behavioral level of abstraction, and the later implementation stages with its structural level of abstraction. The language provides hierarchical constructs, allowing the designer to control the complexity of a description. Verilog was originally designed in the winter of 1983/84 as a proprietary verification/simulation product. Since then, several other proprietary analysis tools have been developed around the language, including a fault simulator and a timing analyzer; the language being instrumental in providing consistency across these tools. Now, the language is openly available for any tool to read and write. This book introduces the language. It is sometimes difficult to separate the language from the simulator tool because the dynamic aspects of the language are defined by the way the simulator works. Where possible, we have stayed away from simulator-specific details and concentrated on design specification, but have included enough information to be able to have working executable models. The book takes a tutorial approach to presenting the language.
