Make Part Compatible

[Update May 21, 2011: click here for additional information about Make Part Compatible function for 7 Series FPGAs]
The "Tools->Make Part Compatible" function checks the pin compatibility between current selected part and a new device in the same package. The tool creates a spreadsheet that lists all pins from both parts side by side and highlights incompatible pins in red. The “PROHIBIT” column for all incompatible pins are set to yes (“Y”). Once the spreadsheet is reviewed, users can write out a UCF file with PROHIBIT constraints added for all incompatible user IOs.
