Many of the changes are relaxations to rules previously in VHDL, and will make some modeling tasks easier. Other changes are clarifications or corrections to minor inconsistencies in the language definition.

Referencing Generics in Generic Lists

In earlier versions of VHDL, a formal generic declared within a given generic list could not be used to declare other generics in that list. The same rule also applied to ports declared within a port list and to parameters declared in a subprogram’s parameter list. In VHDL-2008, the rule is relaxed for generics. Thus, we can use one ...
