Critical Warning (18964): Dedicated HPS IO Voltage mismatch. The VCCIO_HPS is set as 1.8V but the HPS dedicated pin is set to an IO standard of 3.0V

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Quartus® Prime software version 16.1, Critical Warnings for dedicated HPS IO voltage mismatch may be erroneously generated for Arria® 10 HPS shared IO pins.

    • The legality check in the Quartus Prime software version 16.1 erroneously compares the VCCIO_HPS setting to the pins in the HPS shared IO48.
    • The VCCIO_HPS setting must the IO voltage in HPS dedicated IO. 

     

    Resolution

    This critical warning can be ignored in the 16.1 Quartus Prime software if:

    • VCCIO_HPS matches the voltage on HPS dedicated pins
    • The VCCIO on the relevant shared IO bank matches the IO standard on the HPS Shared IO Pin

    This problem is scheduled to be fixed in a future release of the Quartus Prime software.
