Chapter 3 provides an overview of the basic language constructs of VHDL, including lexical elements, objects, data types and operators. Because VHDL is a strongly typed language, the data types and operators are discussed in more detail. | Basic Language Constructs of VHDL RTL Hardware Design by P. Chu Chapter 3 1 Outline 1. 2. 3. 4.
