I've to import in system generator a "big" black box.
This block is composed by a lot of vhdl subfiles and I don't know the right comilation order (but I can reconstruct it by ISE).
There is a way to add all the vhdl files quickly (for example using wildcards) ?
You have to modify the _config.m file to add all the files.
These will then be added to the ISE project approriately, so the order isn't necessarily important for synthesis.
I think iSim will also figure out the compilation order, but you might need to put them in the correct order if you are trying to simulation with ModelSim.
