How to connect unused GXB_TX pins in an ARRIA GX device

I am trying to figure out how to terminate unused GXB_TXp and GXB_TXn pins in an Arria V GX device. Thanks, Dan

Thank you for the response.

Yes, I did read that document.

It says "Leave all unused GXB_TXp pins floating", which seems to inply to float just the "p" pins.

Hence my confusion.

I see what you mean. It's a typo. Leave both pins floating. You should let Altera know about this. Check the PCG for Cyclone V, Arria 10, etc. They correctly say to leave both pins floating.
