grades. Fixed-voltage devices are also available, but only in –4 speed grade. All
SmartVID standard power devices must be driven by the Power Management BUS
™
(PMBus
slave mode.
Intel Agilex devices also offer power-gating feature to the digital signal processing
(DSP) blocks, M20K memory blocks, and clock signals that are not in use for static
power savings. You can enable this feature through the Intel Quartus
This user guide describes the power-optimizing features of the Intel Agilex device
family, and the power-up and power-down sequencing requirements for the Intel
Agilex devices.

1.1. Power System Design Phases

Power system design is done in the following logical phases.

1.1.1. Choosing a Power Tree

A power tree topology is chosen based on the requirements of your device.
The requirements of the power supply may not yet be known, but you can access the
supply voltage and connection requirements from the Intel Agilex Device Family Pin
Connection Guidelines and the power tree selector guides in the Intel Enpirion
Resource Center. Any required power supply sequencing and SmartVID usage will
impact the power tree topology.

1.1.2. Power Estimation

The amount of electrical power required by the various device power supplies is
estimated using the Early Power Estimator (EPE) tool and the Power Analyzer tool.
As the design evolves to the final configuration, the quality and type of information
available improve and the estimation becomes more accurate.
