Why is an SEU error reported in Intel® Agilex™ devices with Intel® Enpirion® Power Module ED8401 and Intel® Quartus® Prime Pro Edition software versions 21.3 and 21.4?

Environment

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

    When using Intel® Enpirion® Power Modules, you may see an SEU error reported when using Intel® Agilex™ devices and Intel® Quartus® Prime Pro Edition Software versions 21.3 and 21.4.

     

    This SEU error is reported because the voltage required by Intel® Agilex™ devices is higher than the default Over-Voltage (OV) warning setting in the Intel® Enpirion® Power Module ED8401.

    The OV warning is recorded by Intel® Agilex™ devices as an SEU error.

     

    You may see the SEU error as shown in the screenshot below if you use the Configuration Debugger Tool (refer to AN 955: Programmer’s Configuration Debugger Tool).

     

     

    Resolution

    To fix this problem,  set the VOUT_OV_WARN_LIMIT of ED8401 to be 950mV.

    In general, refer to Intel® Agilex™ Power Management User Guide, chapter "Fault Management and Error Reporting", to set all the relevant parameters in the voltage regulator properly.
