Error (175005): Could not find a location with: GPIO_SHARED_NOE0 of (locations affected)

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    This error may be seen in Intel® Quartus® Prime Pro Edition software during compilation of an Intel® Agilex™ device targeted design that contains the Generic Serial Flash Interface Intel® FPGA IP design with exported conduits. This is because there is an Output Enable (OE) conflict in the design pin placement. The error may be duplicated on different pins assignments if there are multiple OE conflicts being detected.

    In Intel® Agilex™ devices, there is a pin placement requirement due to the fact that the OE hardware is shared amongst x4 DQ group pins. Thus, if there are 2 conduits having their own respective OE signals, they should be assigned to different x4 DQ group pins to avoid OE conflicts.

    Resolution

    To avoid this error, exported conduits with different OE signals should be established in a different x4 DQ group, whereas exported conduits with a shared OE signal are recommended to be established within the same x4 DQ group. Example using an Intel® Agilex™ AGFB027 device is shown below:
