If you are migrating from a GTX or GTH transceiver for a 7 series device to a GTH or GTY transceiver for an UltraScale™ device, the prefixes of the optional transceiver debug ports for single-lane cores are changed from gt0 to gt , and the postfix _in and _out are dropped.
IMPORTANT: Update your design to use the new transceiver debug port names. For more information about migration to the UltraScale architecture, see the UltraScale Architecture Migration Methodology Guide (UG1026) [Ref 13] .
