General Description: Upon running the synthesize process in ISE Webpack 6.1.01i, I am issued the following fatal error:
- bad nph file Process will terminate
ERROR: XST failed
Resolution: This error has been seen to be caused when an older version of the foundation software - 4.1i - is also installed. Either remove the old foundation software and re-install the ISE 6.1 software or be sure both versions are installed to separate unique root directories, changing the path and environment variables appropriately.
