Bank definition and voltage levels on different (Sub?)Banks

Hi,

Can You provide some kind of clarification: when the documentation states that the banks of FPGAs can have different voltage standards does this statement refers to different bank numbers or subbanks (i dont know how to call them?).

I mean:

I know i can power BANK 3 and BANK 7 with different voltages

but,

can I power BANK7B and BANK7C with different voltages?

Does they count as different Banks?

All this (SUB?)Banks have their separate power supply and predrivers accordingly (In Cyclone V SoC for example).

    Yes, you can power these banks at different voltages. If in doubt use Quartus to confirm such questions. Put a simple design together and specify the I/O standards you want on each bank. Quartus will confirm whether it's valid or not.

    Cheers,
