Why does the example design for the UniPHY-based memory controller have an Avalon-MM slave port as top-level I/O?

Environment

    Quartus® II Subscription Edition
    DDR3 SDRAM Controller with UniPHY Intel® FPGA IP
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

UniPHY-based memory controllers with the On-chip Debug Toolkit enabled will have an Avalon®-MM slave port exported to the top level of the example design. The additional pins required by the Avalon-MM slave port could lead to "No Fit" errors for some smaller package sizes.

 

Resolution

To remove the Avalon-MM slave port, disable the On-chip Debug Toolkit and regenerate the example design, or manually remove the Avalon-MM slave port from the top level.

This issue has been fixed in the Quartus® II software 13.1 version.
