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

Thank you.
I changed device to 780 pin device from 1152 pin device(Because of cost).
And I cannot assign ddr3 in bank3.(Lack of a pin)
So I assign ddr3 to bank4 and 7(I use 2 ddr3 devices).
Bank7 has RUP/RDN pin.Bank4 has no RUP/RDN pin.
RUP(BANK7) is connect to 1.5V.VCCIO of BANK4 and 7 is 1.5V(VCCPD=2.5V).
It is same VCCIO voltage,so I can calibrate BANK 4 and 7 with the cal block(BANK7) associated RUP and RDN of BANK7.
Is it right?
