Just FYI, it is not necessary to have the DDR3 in Bank3A because the ArriaII supported OCT on all I/O pins. You can calibrate the I/O banks with any of the OCT cal blocks available in the device provided the VCCIO of the I/O bank with the pins using cal OCT matches the VCCIO of the I/O bank with the cal block and its associated RUP and RDN pins
