Hi!

In my design, some FPGA inputs could be left unconnected. But the value of this unconnected pins must be 0.

I've found out that by default this pins are set to 1. So it is force me to connect output source to all pins, otherwise it won't work properly.

The question is, how could I set this temporary unused pins to 0? I use Quartus II.

Thank you!

Wouldn't it simply to just set your pins as GND source instead of VCC on your input pins?
