How to implement "dual channel mode" to get effective bit width of 128bits while operating with DDR4 with Arria10 device?

HI,

You can instantiate two DDR4 IP, each with 64 DQ width to get total of 128 DQ width support.

Thanks.

I observed that the total number of DQ pins available in DDR4 is 64. By instantiating two DDR4 IP , will I be able to access 128 bits simultaneously in the same clock cycle?
