5.1.4. Intel Agilex Power Management and VID Implementation Guide

The Intel Agilex SDM Power Management Firmware manages the SmartVID
configuration and enables the FPGA to power up before you can access the FPGA. The
Intel Agilex device is connected to the external voltage regulator through the PMBus
interface.
5.1.4.1. Intel Agilex Power Management and VID Interface Getting Started
The Intel Agilex Power Management and VID interface is installed as part of the Intel
Quartus Prime software.
5.1.4.1.1. Specifying Power Management and VID Parameters and Options
1. Create an Intel Quartus Prime project using the New Project Wizard available
from the File menu.
2. On the Assignments menu, click Device.
3. On the Device dialog box, click Device and Pin Options.
4. On the Device and Pin Options dialog box, click Configuration.
5. On the Configuration page, specify the VID Operation mode. There are two
modes available—PMBus Master and PMBus Slave.
6. The PMBus modes require these pins—
PWRMGT_ALERT
Configuration Pin Options. The
the slave mode. For the configuration pin parameters, refer to
24.
7. On the Configuration Pin dialog box, assign the appropriate
power management pins. Click OK.
8. On the Device and Pin Options dialog box, click Power Management and VID
to specify the device settings if your device is in the PMBus Master mode. Click
OK. For the power management and VID parameters, refer to
25.
This completes the SmartVID setup for the Intel Agilex device.

Description
This is a required PMBus interface for
the power management when the VID
operation mode is the PMBus Master or
PMBus Slave mode.
Disable this parameter for the non-
SmartVID device.
Intel recommends using the SDM_IO14
pin for this parameter.
