Generic Packages

[Guest_imported]

Does someone know how can I write a generic package (using the generic keyword) in order to pass an integer (for example) to the package upon usage? I know it's possible in Ada, but didn't find it in the books I have about VHDL...

thanks.

Packages do not have generics. Only entities may have generics. You can however, have deferred constants that are elaborated during the simulation of the design.
Deferred constants are not synthesizable.
