We are using a FLEX Dongle license.
In Vivado 2013.1 or ISE 14.5 design tools, it appears that the dongle is not recognized.
FLEXnet Licensing error:-5,357
For further information, refer to the FLEXnet Licensing documentation, available at "www.flexerasoftware.com".
The hostid of this system does not match the hostid specified in the license file.
I can see that the dongle is present and recognized by FLEX license utilities. Running "lmutils lmhostid -flexid" returns the correct dongle ID.
The dongle and license still work for ISE Design Suite 14.4 and older Xilinx software versions.
Vivado 2013.1 and ISE Design Suite 14.5 software licensing does not correctly recognize a hardware dongle.
Although a Dongle is present and recognized by lmutils, it does not appear to be recognized by ISE 14.5/Vivado 2013.1 tools.
