How to connect bus data type to external port interface?

Hi,

I have simple model to test. I would like to use bus input and output port. busInput is bus with 3 int16 type element. Integer gain is multiplied in the model.

I would like generate Vivado IP core with this model. HDL code generated but in the HDL Workflow advisor, I got error when I try to select the "External port", saying "Interface 'External Port' does not support bus data type on port busInput"

1. Is it possible to assign bus data type to target interface? if yes, how?
2. if not, what would be best way to assign a bundle of data element instead using individual external port?

Regards,

Bus support for External Port is not yet supported in HDLCoder and is under active development and will be available in the near release;

AXI4-Stream Video, AXI4-Stream, AXI4-Master support bus type at External Port Interface.

Please consider scalarizing the bus port at the top level DUT interface and recreating the bus port internally.
