    Re: Block box design error in Vivado

    Vivado doesn't natively use ngc files from ISE.

    Is this a FIFO IP core from ISE you are trying to use? How did you read this file in? Did you start a post synthesis project or did you use read_edif to read in the ngc file.

    What version of ISE was the core from and what is the version of the core. Also what version of Vivado are you using?

    If possible I would re-generate the cores within Vivado.

    Regards

    Okay, I understand that you're migrating an ISE project to Vivado. I had the same issue with having to use manual compile order to get around problems with the cores on a migrated ISE project.
