摘要
An integrated circuit capable of monitoring analog voltages inside an analog block is presented. The integrated circuit has an analog test multiplexer (mux) whose inputs are connected to analog voltages of interest inside an analog block. The analog test multiplexer directs a selected analog voltage from an analog block to the output of the analog test mux. The integrated circuit further includes an analog monitor state machine which provides the selection bits to the analog test multiplexer, enabling random access to the analog voltages inside the analog block. The integrated circuit also includes an analog to digital converter for converting the selected analog voltage from the analog test multiplexer into a digital representation.
