Why is an SEU error reported in Agilex™ 7 devices with Intel® Enpirion® Power Module ED8401 and Quartus® Prime Pro Edition Software versions 21.3 and 21.4? - Why is an SEU error reported in Agilex™ 7 devices with Intel® Enpirion® Power Module ED8401 and Quartus® Prime Pro Edition Software versions 21.3 and 21.4? Description When using Intel® Enpirion® Power Modules, you may see an SEU error reported when using Agilex™ 7 devices and Quartus® Prime Pro Edition Software versions 21.3 and 21.4. This SEU error is reported because the voltage required by Agilex™ 7 devices is higher than the default Over-Voltage (OV) warning setting in the Intel® Enpirion® Power Module ED8401. The OV warning is recorded by Agilex™ 7 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 Agilex™ 7 Power Management User Guide, chapte r "Fault Management and Error Reporting ," to properly set all the relevant parameters in the voltage regulator.
