Why do I see hold time violations when I compile the CPRI MegaCore targeting a Stratix IV GX device?

Environment

  • CPRI
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    The Altera® Quartus® II software version 9.1 SP1 Fitter cannot fix hold time violations between the ALTGXB and the core logic that involve the transceiver recovered clock.  To fix these hold time violations, please download and install the following ACS patches.

    This issue will be fixed in the Quartus II software version 9.1 SP2 release.
