When migrating from a 7 series GTX or GTH transceiver device to
an UltraScale architecture GTH transceiver, the
prefixes of the optional transceiver debug ports for single-lane cores are changed
from “gt0”, “gt1” to “gt”, and the postfix “_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 rule applies for all ports, with the exception
of the DRP buses which follow the convention of gt(n)_drpxyz.
Important: Update your design to use
the new transceiver debug port names. For more information about migration to UltraScale architecture devices, see the
UltraScale Architecture Migration: Methodology Guide
(UG1026)
Important: When upgrading across
different devices, you need to double check the GT locations and corresponding
customization parameters for a new target
device.
