Internal Connections on FPGA

I am making a schematic with many inputs, more than the number of pins available on the FPGA.

This schematic should serve as a block for another schematic and the various inputs should be internal links and many should be left free.

 

Quartus II, however, does not compile telling me that there are not many pins on the FPGA to be able to satisfy my schematic.

 

How can I say that they are internal connections and that I do not have to assign them to the external pins of the FPGA?

That's exactly what virtual pins are made for in Quartus. Just assign the input pins as "Virtual Pin -> On" in the assignment editor.

It's a bit messy to use, but I did it and now it works.

Thank you!
