[[Image:SPI-like bus.JPG|thumb|SPI-like bus topology]]
In order to monitor the voltage levels of the power lines, an ADC is to be included in the design. The Analog Devices' AD7928 is an eight-channel ADC. Based on the selection of components there are six necessary power lines and two necessary grounds, so the AD7928 is capable of monitoring the entire system if need be. It uses a serial protocol that is compatible with the SPI bus to communicate with the FPGA.
