You can use the differential pairs as 2 single ended I/Os. You can of course use only one pin of the pair and leave the other unconnected.

How to use differential pairs as 2 single ended IO?

What configuration to set in Quartus or hardware?

As far as I know, I thought to use single ended IO, I just need to reconfigure it at pin planner so that it has IO standard 2.5V instead of LVDS isnt it? Please correct me if I am wrong because I am currently configuring the HSMC pins.

thank you.
