Why are the RREF pins identified as GND pins in the pinout (.pin) file for Arria II GX devices?

Environment

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

    The pinout file created by the Quartus® II software versions 9.0 and 9.0 SP1 incorrectly identifies the RREF pins as GND pins in Arria® II GX devices.  The RREF pins connect to GND on the PCB but through precision 2-kohm resistors as specified in the Arria II GX Device Family Pin Connection Guidelines (PDF).

    This problem is fixed beginning with the Quartus II software version 9.0 SP2.
