DDR4 connection to Arria10

Hi.

How to connect the pins of the DDR4(1200 MHz) chip to the Arria10 chip? How to determine where to connect?

For example I want to use a 3A Bank and a 512x8 DDR4 chip or a 3A and 3B banks and a 253x16 DDR4 chip.

In Bank 3A(512x8 DDR4):

W9 - VREFCA

AA13 - RZQ resistor 240 Om

AD3, AC3 - input refclk dif pair 300MHz

AE2, AD2 - DQS dif pair

AC1, AC2 - output for clk pair DDR4 chip

AE1, AF2, AG1, AF1, AG3, AF3, AH2, AH3 - DQ[7:0]

And the rest of the signals to connect to any free contacts, isn't it?

Are the contacts used in the Bank 3B the same way?
