SmartVID

During manufacturing testing, Intel determines the optimum operating conditions for the core performance. A set of voltage values corresponding to those conditions are then programmed into nonvolatile registers in the device. The contents of these registers, and information about the silicon temperature, control the output of the voltage regulators, minimizing power consumption.

SmartVID has a large number of very small voltage reduction steps. Using SmartVID, the Intel® Arria® 10 device operates at the lowest possible voltage for a given speed grade. This enables power savings without sacrificing performance. SmartVID is offered as device-specific features. If you want to use either of these features, ensure that you order the correct product corresponding to the feature. For more information, refer to the " Intel® Arria® 10 Device Variants and Packages" section of the Intel® Arria® 10 Device Overview.

Intel® Arria® 10 SmartVID devices power up at default voltage (0.9 V). After the power-up sequence and device configuration, lower voltage is applied. This reduces VCC SmartVID voltage to a value between 0.9 V and 0.85 V. When the junction temperature of the device is below 0° C, the voltage is increased to the original value.
