Why are the VOD, pre-emphasis, and slew rate parameters reported as -1 for Stratix V, Arria V, and Cyclone V transceiver pins in the Resource Property Editor when using Quartus II software version 13.0 and 13.0sp1?

Environment

  • Stratix® V GT FPGA
  • Stratix® V GS FPGA
  • Arria® V GX FPGA
  • Cyclone® V GT FPGA
  • Arria® V GZ FPGA
  • Arria® V GT FPGA
  • Stratix® V GX FPGA
  • Cyclone® V GX FPGA
  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a bug in Quartus® II software versions 13.0 and 13.0sp1, VOD, pre-emphasis, and slew rate parameters are incorrectly reported as -1 for Stratix® V, Arria® V, and Cyclone® V transceiver pins in the Resource Property Editor.

    Resolution

    You can refer to the fitter results for the assigned VOD, pre-emphasis, and slew rate parameters.

    This problem will be resolved in a future version of the Quartus II software.
