If the following conditons are met, an Intel® Agilex™ device may fail during configuration:
- The Intel® Agilex™ device design project is updated from the Intel® Quartus Prime® Pro Editon Software v21.2 or earlier to v21.3 or later
- PMBus Master is used in VID mode in the Configuration setting under Device and Pin Options
- Auto Discovery option is used in Voltage output format in the Power Management & VID setting under Device and Pin Options
This is because the Auto Discovery option is no longer supported in Intel® Agilex™ devices since Intel® Quartus® Prime Pro Edition Software v21.3. When Auto Discovery option is used and the Intel® Quartus Prime® Pro Edition Software version is updated from v21.2 or earlier to v21.3 or later, the following message is displayed in the System Message window:
Info(22747): Value AUTO_DISCOVERY for QSF Assignment PWRMGT_VOLTAGE_OUTPUT_FORMAT is not supported. Hence changing the value to LINEAR_FORMAT
Set the Power Management & VID settings based on the power requlator device.
Example
Intel® Agilex™ F-Series FPGA Development Kit - Analog Devices LTC3884 version
Intel® Agilex™ F-Series FPGA Development Kit - Intel® Enpirion® device ED8401 version
