VHDL Data TypesSummary
All declarations of VHDL ports, signals, and variables must include their associated type or subtype
Three forms of VHDL data types are :
- Access -- pointers for dynamic storage allocation
- Scalar -- includes Integer, Real, Enumerated, and Physical
- Composite -- includes Array, and Record
A set of built-in data types are defined in VHDL standard
- User can also define own data types and subtypes
