VHDL supports a rich set of built-in data types as well as user-defined data types

 

 

Data Type

Characteristics  

BIT

Binary, Unresolved

BIT_VECTOR

Binary, Unresolved, Array

INTEGER

Binary, Unresolved, Array

REAL

Floating Point

 

 

 

   Built-in data types work well for simulation but not so well for synthesis

 

 

   Built-in data types are suitable for use inside an architecture but should not be used for external pins
