ADEPT shows unbonded IOBs. You can copy and paste them to an editor or export the list to Excel spreadsheet. It is availabe at

Thanks,
I;ve opened adept with the correct package/fpga. All the pins seem to be physically connected, is there an option somewhere for viewing the unbonded iob's?
Thanks a lot,
Alastair
Not all device/package combinations have unbonded IOBs. Usually a big device in a small package have unbonded IOBs. As an example, if you open 4vlx25sf363 in ADEPT, it will displays all unbonded IOBs (UNB_XmYn pins) in this package.

Ok thanks, so the 4vlx25ff668 doesn't have any?
Look at the data sheet: The family overview in table 1 tells you that the chip has 448 IO. Table 2 then tells you that the SF363 package has 240 available IO, and the FF668 package has all 448 IO brought out.
