Unused bank - VCCPD, VCCIO and VREF pins

Hello everyone, If I do not want to use a certain bank of the Cyclone V, do I have to power the VCCPD, VCCIO and VREF pins? Cheers, Adam

Keep the power rail connected even if you are not using it. Not much power consumption. If for some reasons you cannot connect a rail to it, at least keep those POR monitored supplies connected.
