Non-Assignment in ARRIA II GX Pin Planner

Hi,

I am trying to assign the DDR3 SDRAM pins to Bank 7A of ARRIA II GX FPGA. But the same is showing compilation errors "The I/O Standard is compatible with this bank "

The I/O standard chosen is SSTL Class-I 1.5V and this is as per development board guidelines.

Please Help..

    The reason for the error message can be, that you have assigned I/O standards with a voltage different from1.5V to the same bank.

    No, I have assigned the same I/O standards with a voltage different of 1.5V to the same bank of 7A
