Why is the dedicated transceiver refclk pin Vicm lower than the specification in the Arria V GX device datasheet when using Quartus II software versions 12.1sp1 and earlier?

Environment

  • Arria® V GT FPGA
  • Arria® V GX FPGA
  • Arria® V ST SoC FPGA
  • Arria® V SX SoC FPGA
  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    The dedicated transceiver refclk pin Vicm is lower than the specification in the Arria® V GX device datasheet due to a bug in Quartus® II software versions 12.1sp1 and earlier.
