There are 16 power supply rails which have on-board voltage and current sense
capabilities. These 8-channel differential 24-bit ADC devices and rails are split from
the primary supply plane by a low-value sense resistor for the ADC to measure
voltage and current. A serial peripheral interface (SPI) bus connects these ADC
devices to the MAX II CPLD EPM2210 System Controller as well as the Stratix IV GX
FPGA.
