Could some one explain some thing in this schematic please :)

Im very new to FPGA's and am using this attached schematic to crib from. every thing makes sense apart from the following FPGA pins pins 26,81 held high to 1.2v pins 27,80 held to ground ...

ok cool im not actually using the EP2C5 in my project but the Cyclone EP1C3 but figured this EP1C3 schematic would be close enough to copy from (i know the core io voltages are different :))

Im guessing i dont need these extra power pins on the EP1C3 i just need to connect up the standard VCCIO(3.3)/VCCINT(1.5) power pins :)

Thanks for all your help :)
