    Hi Aik,

    there are pending question from above. It would be good to understand if using empty signal is mandatory now (as it was not required for the same interface definition in i++ HLS).

    The second, related question is about conformability to the Avalon ST definition.
    Digging deeper in this I see some long time pending changes which may have influence to the above interface definition requirement:

    To create production designs with this feature it is necessary to have clear and consistent documentation and specifications.

    Any outlook on what is going on in sycl HLS for this topic?

    Thanks,
    Ric.
