Access Types and Abstract Data Types
We have seen in previous chapters how we can use variables within processes to create data that is associated with a name. We can write a variable name in a model to read its value in expressions and to update its value in variable assignment statements. In this chapter, we introduce access types as a mechanism in VHDL-AMS for creating and managing unnamed data during a simulation.
20.1 Access Types
The scalar and composite data types we are now familiar with can be used to represent either single data items or regular collections of data. However, in some applications, we need to store collections of data whose size is not known in advance. Alternatively, we may need to represent a complex ...
