Error (165011): altmemphy pin placement was unsuccessful

Environment

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

    When you implement the DDR3 SDRAM Controller with UniPHY in a MAX® 10 device and add pin location assignments to the DQSn pins in the QSF file, you may get following fitter error.

    Error (165011): altmemphy pin placement was unsuccessful

    Error (13130): The assigned location PIN <pin_number> for DQSn pin mem_dqs_n[*] is not a legal location

    As DQSn is a pseudo differential pin of DQS, a pin location assignment for DQSn is not needed. The pin location  assignment on the DQS pin is sufficient.

    Resolution

    To work around this error, remove the pin location assignment for the DQSn pins in the Assignment Editor or the QSF file.
