VHDL: Programming by Example

CHAPTER 4

Data Types

In this chapter, we examine the object types used in VHDL. The types allowed in VHDL consist of everything from scalar numeric types to composite arrays and records to file types. The first step in looking at the varied VHDL types is to review the VHDL objects that can attain the varied types. Then we use examples to show how many types of descriptions can be made easier to read by using the power of enumerated and composite data types.

Object Types

A VHDL object consists of one of the following:

Signal, which represents ...
