Voltage Monitoring Circuit for Interface
Abstract:
A voltage monitoring circuit is disclosed. An apparatus includes a first physical interface circuit and a real-time oscilloscope circuit configured to monitor a first voltage provided to the first physical interface circuit. The real-time oscilloscope is configured to receive an indication that an error was detected in data transmitted from the first physical interface to a second physical interface circuit. The real-time oscilloscope is further configured to provide for debug, to a host computer external to the first interface, information indicating a state of the first voltage at a time at which the error was detected.
