    Hi @myg,

    There can be several reasons why hyper-optimized handshaking is "off" even though you are targeting Stratix 10.

    The reason that hyper-optimized handshaking is "off" should be given in the optimization reports.

    Please look for a column called "Hyper-Optimized Handshaking" in the Kernels Summary table of the Summary section of the report.

    By clicking on an entry in this column, you should see the reason appear in the Details pane below. For example, the reason might be:

    • Hyper-optimized handshaking disabled due to instruction in Kernel my_kernel_name

    I hope this helps you find the information you're looking for!

    The most likely performance impact of no hyper-optimized handshaking, is lower achieved Fmax.

    Best regards,

    Jessica
