System Generator for DSP v13.x - "ERROR: A license checkout has failed for System Generator for DSP"


If I run MATLAB with System Generator and try to generate a model, an error similar to the following occurs:

ERROR: A license checkout has failed for System Generator for DSP (SysGen).

------------------- A message from the license manager --------------

No such feature exists.
Feature: xc4vlx15
License path: C:\Programs\Xilinx\lic\Xilinx.lic;H:/.Xilinx\Xilinx.lic;
FLEXnet Licensing error:-5,357
For further information, refer to the FLEXnet Licensing documentation,

Reported by:


This error has been reported with multipledevices other than theone listed above.

This issue can be caused by an improper environment setup when running MATLAB with ISE 13.x design tools.

To work around this issue, run System Generator (Start -> All Programs -> "Xilinx ISE Design Suite" -> System Generator -> System Generator) to open MATLAB.Starting System Generator in this way runs the"C:\Xilinx\13.x\ISE_DS\ISE\sysgen\util\startsg.bat simulink nt64" option (or similar, depending on 32 or 64-bit). NOTE: This option will not be run when opening MATLAB standalone or opening a .mdl file.
