conditionnal import package in SV

Hello everyone,

I want to select package depending of parameter. I have the same parameters which different value in this two packages : pkg_std, pkg_a. And I would like to select the good one depending of the mode A

I don't know if it's possible.

Modelsim get an error on this :

Parameter A = 0;

if(!A)
begin
     import pkg_std::*;
end
else
begin
     import pkg_a::*;
end

It s seems a conflict between the two packages, because all parameters declared into the package are "undefined variable".

I'm curious if you have already to attempt this?

Let me know, please.

Thanks a lot.

Bye, JP LM
