126.96.36.199. SmartVID Feature Implementation in Intel® Stratix® 10 Devices
Devices supporting the SmartVID feature have a VID-fused value programmed into a fuse block during device manufacturing. The VID-fused value represents a voltage level in the range of 0.8V to 0.94V. Each device has its own specific VID-fused value.
The VID-fused value is sent to the external regulator or system power controller through the PMBus interface. Upon receiving the VID-fused value, an adjustable regulator tunes the VCC and VCCP voltage levels to the voltage specified by the VID-fused value.
Intel® Stratix® 10 devices perform the SmartVID setup in the early stage of the configuration process. The SmartVID process will continue to monitor the VCC and VCCP voltage rails in user mode. The Power Manager monitors the temperature and adjusts the voltage when required. For more information, refer to the Temperature Compensation section.
