Critical Warning (11887): The following pin <data pin> was placed in a reserved GND location. This may cause decreased performance for HMC. Altera recommends the pin location to be grounded

Environment

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

    The following critical warning may appear after the fitter stage when an unused data pin is placed on a reserved hard memory controller (HMC) GND pin.

    Critical Warning (11887): The following pin <data pin> was placed in a reserved GND location. This may cause decreased performance for HMC. Altera recommends the pin location to be grounded

     

    Resolution
