Is the voltage regulator listed in the Intel® Quartus® Prime GUI drop down?5

In Intel® Quartus® Prime: Assignments > Device... > Device pin and options... > Power Management & VID > Slave device type.

The Intel Agilex® 7 devices with -V, -E, and -X suffixes use the SmartVID feature, which requires a voltage regulator that is PMBus compliant to provide power to VCC/VCCP. All the PWRMGT_SDA, PWRMGT_SCL, PWRMGT_ALERT (for Slave mode) signals must be connected with a 1.8V I/O standard.

For more information about Smart VID and Voltage Regulator, refer to the Intel Agilex® 7 Power Management User Guide and AN 974: Intel® Stratix® 10 and Intel Agilex® 7 SmartVID Debug Checklist and Voltage Regulator Guidelines.

5 Intel® recommends that you use a voltage regulator listing in the Intel® Quartus® Prime drop down menu Slave device type as these regulators are all fully tested and validated. If you choose an alternate regulator, ensure that it meets all the criteria listed in the Intel® Power Management User Guide.
