I'm currently working with ISE 7.1
I'd like to be able to assign FPGA pins to a submodule either via a ucf file, or (preferably) via assigning properties to nets within the module.
To expand-- I'm creating some modules for use as library blocks in a classroom setting. These blocks will always be mapped to static FPGA pins, corresponding to LEDs, pushbuttons, etc, so I'd like to be able to just drag and drop them onto a schematic, without having to create top level I/O markers.
I know this was possible in ISE 2.1 (the version the class is currently using), but is it still possible in 7.1?
