Question: can a port be defined in terms of a localparam?
I think of a localparam as the verilog equivalent of a vhdl constant
declaration. A vhdl port cannot be defined in terms of a constant defined
in the entity or architecture (although it can be defined in terms of a
constant living in a package).
My concern is that a tool may have the following order of processing:
1. process parameters
2. process ports (which may depend on parameters)
3. process other declarations and statements
The question is should localparams be processed in part 1 or in part 3? If
part 3, then clearly a port cannot depend on a localparam. (For that
matter, a parameter cannot depend on a localparam).
