passing generic value

[Guest_imported]

Hi,
My query is regarding passing generic value to the instances. I know how it is done normally ( using
generic map while instantiating or while binding
component in configuration ). But my problem is a little
different. I want to know how to pass a generic value to an entity which is not instantiated anywhere ( its the top level entity ). This top level entity is the testbench entity which is not instantiated but has a generic. I want to pass the generic value in the configuration of this top level entity. When I want to change the generic value I will just change the configuration file.
Regards,
Sharan

If you want to pass a generic value to a top level entity, then have a package file where map this generic to a signal type defined in package(appropriate type). Just use work.package.all in the header portion of top level entity and compile that package before this entity.
