Hi Tricky
thanks for the reply, but I still don't understand, how can I use generics to instanciate for example serial LCD interface, for HW A and a parallel LCD interface for HW B.
I should note that I do have a working knowledge of VHDL and I have used generics for example many times in the past, but that was for the portability of small blocks. for the top entity I've always used the schematic entry, and I''d let it take care of all instantiations etc.

You can use the if...generate construct in VHDL to conditionally instantiate modules and wire them up, can't you? Except of this, in VHDL you can control the different architectures used by writing configurations.
