Hi, 

 

I'm new with Quartus and I have a question. I have a design where i use 7 4-pins NAND gates connected to one 8-pins NAND gate. When I'm trying to compile, it doesn't work because of the pin not connected in the 8-pin NAND gate. My question is, what should I do with that unused pin? How should I connect it? 

 

Thank you very much for your help.

You can make an 8 input NAND gate function as a 7 input NAND gate by tying the unused input high.
