    Hi QY,

    I followed the steps in the AN 985 user guide, but I can not replicate the issue you are seeing;

    Could it be that niosv.data_manager is not connected to jtaguart.avalon_jtag_slave?

    That is very likely the issue. The Nios V is only connected to internal memory in your design. I.e. it has no connections to the outside world and as such has no useful functionality. The Quartus Tool removes any such blocks.  My guess, the Nios V got optimized away.

    Please connect the CPU like I have done below and try again.

    Cheers,
    Richard

    Hi Richard,

    After connecting to niosv.data_manager, we can see the logic elements for Nios V.

    Thanks.
