Thanks, DanForum Discussion

Have you read the Arria V pin connection guidelines? https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/dp/arria-v/pcg-01013.pdf This is a very important document for all families. It says to leave all unused GXB_TX pins floating. No need to terminate.

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

Check the PCG for Cyclone V, Arria 10, etc. They correctly say to leave both pins floating. Bob
