Virtex-6 FPGA Integrated Block for PCI Express - DRC Error During Simulation using Provided Root Port Model


Version Found: v2.2, v1.4
Version Resolved and other Known Issues: See (Xilinx Answer 45723).

When using ISE 13.1 or later softwareto simulatethe wrapper using the provided root port model, simulation will fail with the following error message:

DRC Error : Value of POWER_SAVE[4] should be set to 1'b1 for instance board.RP.rport.pcie_2_0_i.pcie_gt_i.gtx_v6_i.GTXD[0].GTX of GTXE1.


This erroroccurs due to a new DRC check added inISE 13.1 softwareto ensure users have followed the Virtex-6 GTX workaround fixfound in(Xilinx Answer 39456). If you are using an older version of the core, you must implement this work around. In ISE 13.1 software, once thisworkaround isimplemented, the DRC errors will not happen.

This issues is fixed in the v2.3 or laterfor theAXI-Streaming interface or v1.7 or later for legacy TRN interface wrapper available in ISE 13.1 software.
