6.9.2. Power Measurement
There are 8 power supply rails that have on-board voltage, current, and wattage sense
capabilities using 24-bit differential ADC devices. Precision sense resistors split the
ADC devices and rails from the primary supply plane for the ADC to measure voltage
and current. A SPI bus connects these ADC devices to the MAX V CPLD EPM2210
System Controller as well as the Arria 10 GX FPGA.
