VHDL Functions and Procedures 18 4) In functions, the formal parameters may be input to the function and used as part of the computation of the return value 5) Functions do not change the values of the parameters passed to them; procedures can change the values of the parameters passed to them 6) A procedure does not return a value, but formal

Process är en central VHDL-konstruktion. Alla kod i processen exekveras sekventiellt och alltså Learn what structures in VHDL are synthesized to those parts to be able to code something that will actually make timing. IMO VHDL n00bs should stay away from using functions, for loops, and generate until they are very familiar with how basic stuff like process, if-elsif, case, when, etc are synthesized.

The value returned by an impure function can depend on items other than just its input parameters (e.g.shared variables). In VHDL-93, the keyword end may be followed by the keyword function for clarity and consistancy. VHDL Function VHDL Function Example. To better demonstrate how to use a VHDL function, let's consider a basic example. For this Calling a Function in VHDL.
