Full compulation for large IO pins

IF you're just getting resource estimations for a block, then simply create a new project containing the block and sub-modules you need to compile it. In the assignments editor, create an assignment for Virtual_pins, and assign it to *. That will then ensure all IOs for that module are assigned virtual pins allowing you to compile your module and get logic usage. You will still need to pick a device - I suggest using the same device as your eventual target.
