Scalar Data Types, Natures and Operations
The concepts of type and nature are very important when describing data in a VHDL-AMS model. The type or nature of a data object defines the set of values that the object can assume, as well as the set of operations that can be performed on those values. A scalar type consists of single, indivisible values. A scalar nature defines values that are associated with a single terminal. In this chapter we look at the basic scalar types and natures provided by VHDL-AMS and see how they can be used to define data objects that model the internal state of a module.
2.1 Constants and Variables
An object is a named item in a VHDL-AMS model that has a value of a specified type or, in the case of a ...
