Arria 10 GX Dev Kit - EMIF Controller Avalon Memory Mapped Slave

Hi,

I am designing user logic to access DDR4 Memory on Arria 10 GX FPGA Development Kit. I instantiated EMIF in Qsys. It has following parameters:

DQ width: 72

Row address width: 15

Column address width: 10

Bank address width: 2

Bank group width: 1

Now, ctrl_amm_0 (Avalon Memory Mapped Slave) for EMIF IP has following signals:

address: 25

burstcount: 7

byteenable: 72

read: 1

readdata: 576

readdatavalid: 1

ready : 1

write: 1

writedata : 576

I can understand larger readdata/writedata size as it works at quarter rate. But what I do not understand is addressing method.

Slave only expects 25 bits as address which is sum of row and column address. How do I specify bank address and bank group?

Thanks and Regards,
