Hi Paul,
You'll need to process them in part 1. Remember, the only
difference between parameter and localparam is that the
localparam cannot directly be set with a parameter override.
Naturally, they will be able to be set by a parameter,
and can be used anywhere inside the module you would use
a parameter... including in port declarations.
Regards,
Stefen
