The Platform Generator calls xst.dll to run synthesis and in some cases this DLL causes some memory corruption.

To work around this issue, you must bypass xst.dll and call the XST executable directly. To do this, change the IMP_NETLIST option in the .mpd file to "OPTION IMP_NETLIST=FALSE". This will move synthesis from PlatGen into the <proj>/synthesis/synthesis.sh batch file.

NOTE: Beginning in the 7.1i release, PlatGen will call the XST executable directly.
