share data pins with address pins of SDRAM in QSYS?

In my design, i must share the data pins of SDRAM with address pin of the same SDRAM,

so how could do that.

Use the sdram controller (share pins via tri-state bridge)?

or use the Generic Tristate Controller?

thank you very much!!

    As far as I know the generic tristate controller can't share the data and address on the same pins. You will need to use a SDRAM controller, or make your own.

    thank you for you reply!

    In QSYS, i select the SDRAM controller and avalon-MM tristate bridge, then in the SDRAM controller I select the tristate bridge as share pins via tristate bridge.

    but how could i connect the "avalon memory mapped tristate master" port of avalon-MM tristate bridge module?
