Schematic Signal Name
There are six power supply rails which have on-board voltage and current sense
capabilities. The power supply rails are split from the primary supply plane by a
low-value sense resistor for the 8-channel differential input 24-bit ADC device to
measure voltage and current. A SPI bus connects the ADC device to the MAX II CPLD
EPM2210 System Controller as well as the Cyclone IV GX Transceiver.
