Why do I get the following Internal Error message when compiling PCI Express design in Quartus II software?


  • Quartus® II Subscription Edition

    Critical Issue


    Due to a bug in the Quartus® II software, "Rapid recompile" can cause Internal Errors when compiling PCI Express Hard IP (under Settings --> Compilation Process Settings --> Incremental Compilation).

    Resolution To workaround this iss please disable the \'Rapid recompile\' option.
    This problem will be fixed in a future version of the Quartus II software.
