This issue arises when a packet is generated at the AXI Slave interface of the AXI Bridge for PCI Express v2.3 (Rev1) core, (for example an outgoing PCIe Memory Write/Read packet).

The core may incorrectly decode AXI BAR addresses which will result in hitting another AXI BAR or missing it entirely.
