How to deal with these unused power pins?

I have a develop kit, On the board the FPGA used nearly all pins and some banks use different voltage, such as 2.5V,1.8V,3.3V. Recently, I build a new project on this board and only used Bank 1 and Bank 2, Bank1 and Bank2 IO use 3.3V voltage. After I compilation the project, the "*.pin" file suggest me to connect the VCCIO3,4,5,6,7,8 to

3.3V voltage, but the board already connected these pin to the other voltage. How to deal with these unused power pins?:confused: Someone can give me some suggestions ?:)

    Different I/O banks can use different supply voltage. You can use them in other than LVTTL I/O standard. Simply, the supply voltage of particular I/O bank determines I/O voltage standard ;) So, you don't have to worry =]
