Issue Details

I cannot export my PLD design to the FPGA Board in Multisim. During step 9 of the export process I get the following error:


This is caused by an issue that affects Xilinx ISE compatibility with Windows 10. Apply the following workaround to fix this issue:


  1. Open your Windows Explorer and navigate to:  C:\NIFPGA\programs\Xilinx14_7\ISE\lib\nt64
  2. Rename libPortability.dll to libPortability.dll.orig
  3. Rename libPortabilityNosh.dll to libPortability.dll
  4. Navigate to:  C:\NIFPGA\programs\Xilinx14_7\common\lib\nt64
  5. Rename libPortability.dll to libPortability.dll.orig
  6. Try programming the FPGA again.
