Do Stratix V devices support a serial configuration device I/O voltage of 2.5V?

Environment

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

    No, Stratix® V devices using Active Serial (AS) configuration devices (EPCQ) do not support a configuration device I/O voltage of 2.5V. When using the AS configuration scheme you must use a configuration voltage of 3.0V.

    Resolution

    Currently in the Quartus® II software version 12.1 and earlier it allows you to select a "Configuration device I/O voltage" of 2.5V but this is a bug and is slated to be fixed in a future version of the Quartus II software.
