The Endpoint v3.5 and v1.7 PIPE for PCI Express CORE Generator customization GUI does not correctly translate the number of MSI vectors requested in the output netlist.
Xilinx Endpoint and Endpoint PIPE solutions for PCI Express support up to 32 MSI vectors. The v1.7 PIPE and v3.4 Endpoint solutions customization GUI does not correctly translate the number of MSI vectors requested (page 6 of 8) into the core netlist. Both the generated netlist and generated simulation model display the error.
This issue will be fixed in the next release of the core. To work around this issue, edit the .xco file and regenerate the core.
Change the line below to request more than one vector:
After editing the XCO, regenerate the core. Open the CORE Generator Project that generated the original core. Click on the "Generated IP" tab and select the core for PCI Express generated earlier. Click on "Regenerate (Under Current Project Settings)". CORE Generator loads the edited XCO file and generates a correct core netlist and simulation model.
