    Hi,

    ​

    Yes,

    the attached image is signalTap waveform.

    It shows that hbm2_ccb bridge send a read request,

    but stuck at the request.

    ​

    The following figure shows block diagram. (Actually it's AN881 reference design for S10 MX FPGA dev. kit.)

    According to attached signalTap waveform,

    CCB send the read request to mm_interconnect_3 which is Qsys component.

    Then mm_interconnect_3 doesn't send the request to axi_bridge.

    We think there must be something wrong inside mm_interconnect.
