    Hi @mahender,

    Thank you for posting in Intel community forum and hope all is well.
    For your query on AXI interface, currently there are no support in HLS for using AXI interface directly.
    We would recommend to use the AXO adapter that are avaialble as part of the IP catalog.

    For that you can refer to the steps and guide here for memory mapped here, or for streaming you can use your own RTL adapter.
    Hope that clarify.

    Hi @mahender,

    Apologies for the delayed in response, if I understand correctly your question.
    Yes you can explicitly customize the mm master interface, more details can be found here.
