How do I enable the internal clamping diode on Arria V and Cyclone V devices?

Environment

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

    Due to a problem in the Quartus® II software version 11.1 SP2 and earlier, there is no assignement for Arria® V and Cyclone® V devices to enable the clamping diode for I/O standards where it is not enabled by default, for example 3.3-V LVCMOS.

    Resolution

    An assignment to enable the clamping diode for Arria V and Cyclone V devices is available beginning with the Quartus II software version 12.0.
