How can I fix this issue?

Solution


This is a known issue on the Virtex-7 1140T and the Virtex-7 2000T devices.

To work around this issue, install the patch at the end of this answer record.

To install the patch, unzip the file and copy the xmd.exe file into the EDK install directory, similar to the following:

For Windows 64-bit
C:\Xilinx\14.4\ISE_DS\EDK\bin\nt

For Linux 64-bit
C:\Xilinx\14.4\ISE_DS\EDK\bin\lin64

The patch also requires an updated version of the "ibSdkHwDb.dll"file to be added to the EDK install directory.

To do this, copy the "libSdkHwDb.dll" file from the relevant location in the ZIP file. For example:

For Windows 64-bit
Copy from lib/nt64 to C:\Xilinx\14.4\ISE_DS\EDK\lib\nt64
