When implementing the Virtex-7 FPGA Gen3 Integrated Block for PCI Express (v1.5 and v2.0) example design generated for 7vx980t-ffg1930-2 device in x8 configuration with PCIe location of X0Y0, the tools run into the following error message:
Running Implement.bat encountered an error ERROR:Place:1340 - PAD.pci_exp_rxn<1> is tied to GTHE_CHANNEL.pcie3_7x_v1_4_i/inst/gt_top.gt_top_i/pipe_wrapper_i/pipe_lane .gt_wrapper_i/gth_channel.gthe2_channel_i which is locked to Site.GTHE2_CHANNEL_X1Y10 This forces the PAD.pci_exp_rxn<1> to be locked to Site.IPAD_X2Y78 which is unbonded on the device!
This error is specific to the ffg1930 device package only.
This is a known issue and is scheduled to be fixed in a future release of the core. The X0Y0 PCIe block location is not valid for the ffg1930 device package. To resolve this issue, select X0Y1 in the core configuration GUI instead of X0Y0.
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.
