10.2 Hprep6 - "ERROR:Cpld - Unexpected IO Bank X encountered for signal XXX; only 0 or 1 expected"


When I try to run Hprep6 to create a JEDEC file for either XC2C512 or XC2C384, the following error occurs:

"ERROR:Cpld - Unexpected IO Bank 3/4 encountered for signal XXX only 0 or 1 expected."


This problem only occurs when theDATA_GATE attribute has been assigned to signals in banks 3 or 4.

It is an issue in the Hprep6 software.

To work around the issue, you can regress to 9.2 with no service pack or move to 11.1 ISE and later software.
