Why does my Megawizard generated Chroma Resampler not compile in Quartus?

Environment

  • Quartus® II Subscription Edition
  • DSP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    The attached simple design contains a Chroma Resampler created in the MegaWizard®  flow.  During compilation, the entire megafunction disappears and generates the following error messages during Analysis & Synthesis:

    Info (12128): Elaborating entity "<your entity name>" for hierarchy "<your entity name>:<your instance name>"
    Warning (277001): IP Generator Warning: This module has no ports or interfaces
    Info (12021): Found 2 design units, including 1 entities, in source file db/<your entity name>_gn.vhd
    ...

    Warning (12158): Entity "<your entity name>_GN" contains only dangling pins

    Resolution Use Qsys to generate the Chroma Resampler.
