Arria-10 SOC DDR4 connections

I am working on a design on the Arria-10 SOC development board and want to connect to the DDR4 socket on connector J27.

Does anyone have an example design with this memory being utilized that has the pinouts? I have been trying to duplicate the connections to the DDR4 on J26 which is the HPS DDR4 but this is a lot of tracing.
