7316 - All Nexus / PCIe: PCIe assignment of 2GB BAR size for 64-bit BAR addressing.
Description:
There is a known bug in the PCIe IP GUI wherein the 64-bit BAR addressing requires that the BAR size be >/= 4 GB only.
Solution:
As a workaround, the user can write the Resizable BAR Capability Configuration (0,1,2,3,4,5) using LMMI or APB to set the BAR size to </= 2GB.
See the table below for the register’s offset address information for Resizable BAR Capability for BAR Configuration 0 to 5 (this is under Hard IP core base address mgmt_ftl (0x04000) register).
This issue has been fixed in CertusPro-NX PCIe IP v2.4.0 and beyond.

PCIe supports both 32-bit and 64 bit addressing. For 32-bit addressing a 3-DW header is used, containing just 32-bits of address info. For 64-bit addressing, a 4-DW header is used, with the extra DW holding the additional 32-bits of addressing.323 - What are the definitions of the BAR bits in PCI/PCIe application?
