    Hi Oleg,

    Thanks for your patience while I was checking the design.

    If you refer to the Platform Designer: Interconnect Requirements, there are some settings that allow the software to automatically insert the clock crossing adapters and add pipeline stages to the Platform Designer interconnect when you generate a system.

    In our case, the clock crossing adapter type is set to FIFO and maximum pipeline stages is set to 4.

    Thanks

    Best regards,
