If you are migrating from a 7 series GTX or GTH device to an UltraScale GTH device, the prefixes of the optional transceiver debug ports for single-lane cores are changed from “ gt0 ”, “ gt1 ” to “ gt ”, and the suffix “ _in ” and “ _out ” are dropped. For multi-lane cores, the prefixes of the optional transceiver debug ports gt(n) are aggregated into a single port. For example: gt0_gtrxreset and gt1_gtrxreset now become gt_gtrxreset [1:0] . This is true for all ports, with the exception of the DRP buses which follow the convention of gt(n)_drpxyz .
It is important to update your design to use the new transceiver debug port names. For more information about migration to UltraScale devices, see the UltraScale Architecture Migration Methodology Guide (UG1026) [Ref 10] .
