VHDL Functions and Procedures - 2023.2 English

Use VHDL functions and procedures for blocks that are used multiple times in a design. The content is similar to combinatorial process content

Declare functions and procedures in:

• The declarative part of an entity
• An architecture
• A package

A function or procedure consists of a declarative part and a body. The declarative part specifies:

• input parameters, which can be unconstrained to a given bound.
• output and inout parameters (procedures only)
