Verilog® HDL: A Guide to Digital Design and Synthesis, Second Edition

Chapter 3. Basic Concepts

In this chapter, we discuss the basic constructs and conventions in Verilog. These conventions and constructs are used throughout the later chapters. These conventions provide the necessary framework for Verilog HDL. Data types in Verilog model actual data storage and switch elements in hardware very closely. This chapter may seem dry, but understanding these concepts is a necessary foundation for the successive chapters.

Learning Objectives

• Understand lexical conventions for operators, comments, whitespace, numbers, strings, and identifiers.

• Define the logic value set and data types such as nets, registers, vectors, numbers, simulation time, arrays, parameters, memories, and strings.

• Identify useful system tasks for displaying ...
