I am trying to integrate a zigbee transmitter with axi-ad9122 in no-os reference design for fmcomms1 with zedboard. I created the hdl files for my transmitter. What I can not understand is that the input ports for axi_ad9122 are connected with two ports in the Vivado design. I checked the constraint file and these two ports are not connected to PS port. So my question is how to find out the data which comes in the axi_ad9122 in order that I can add my transmitter output to axi_ad9122 input.
