Version Found: v1.1 (Vivado 2016.1)
Version Resolved and other Known Issues: (Xilinx Answer 65751)
The GT Quad locations that are shown in the core configuration GUI for Virtex 9P-flgb2104 are 5 quads higher than it actually is in implementation.
For example, when GTY 229 is selected in the GUI, the design will use GTY 224. The GT locations used in implementation is correct and the issue is only in the core configuration GUI.
This is a known issue to be fixed in a future release of the core. To resolve the issue, please install the patch attached to this answer record as described below.
After the patch is installed, the version of the UltraScale+ PCI Express Integrated Block core should indicate: v1.0 (Rev. 67144).
Note: "Version Found" refers to the version where the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
