Unused Pin Behavior

[Altera_Forum]

I have a question about unused pins. Is there a straightforward way to force unused pins to be inactive within a system, without explicitly defining them in a "bdf" file? They could be either Inputs with pullups or they could even be tristate outputs.

You have a global Quartus setting in the device options to achieve just this. Input with weak pull-up or input with hold should be preferred for "inactive" pins. Floating input (just the same as tristate output) can cause additional current consumption and possibly noise.

go to assignments -> settings -> device -> device and pin options ->unused pins 

 there you can select the state for your default pins

Thanks to both FvM and saranshmeh for the helpful replies. I knew immediately about the Device & Pin Options Button, but unfortuneately missed the unused pins tab. I was able to make that change and recompile without incident. I had another problem related to my debugging of a processor interface to an EPCS4 that works in parallel with the FPGA. I'll update that thread with what happened and what I had to do in addition to get theings back where thry were.
