When any design in System Generator is opened and I try to generate the code by pressing the Generate button in the System Generator token, I receive "Post-netlisting script failed - see postnetlist.log for details".
This is a generic message. The most common cause of this error is that the environment variables are set incorrectly. The following variables need to be set under the Path in System Variables:
PATH = C:\Xilinx\bin\nt;C:\WINDOWS\SYSTEM32;C:\WINDOWS;C:\WINDOWS\SYSTEM32\WBEM
XILINX = C:\Xilinx
If there is a "\" at the end of the variable, the error message will still be displayed. Be sure that the XILINX environment variable appears as shown above (where C:\Xilinx is your install directory).
