The problem has been seen to be associated with an incorrect version of the coregen.class file located in
Background: The wincoregen.exe executable was added to fix a problem with a DOS box coming up when the CORE Generator started up on Windows platforms. When this fix was made, the Windows Start Menu shortcut was modified to point to wincoregen.exe instead of the coregen.bat file.
At the same time this fix was added, the CORE Generator Coregen.class file was updated to support the -INITFILE flag The CORE Generator starts up properly using the coregen.class included with the CS4 Service Pack.
This problem appears to have cropped up again in SP5. It will be re-corrected in SP6, due at the end of March. In the meantime, you may request this file by contacting the Xilinx hotline.
