Examples of types are bit, bit_vector, Boolean, character, std_logic, and . In the VHDL file, we have defined a component for the full adder first. .. The scalar type includes integer, real, and enumerated types of Boolean and Character.
Formal Definition. The Enumeration type is a type whose values are defined by listing (enumerating) them explicitly. This type values are represented by

A user defined type in VHDL is always an "enumerated type". "signal assignment statement", as we have seen in the examples of the half adder and full adder.
