In an electronic system having logic agents that communicate with each other through one or more signal lines, a method for testing high speed digital signaling on the signal lines is disclosed. The method involves sensing a first crosstalk signal induced by a first digital signal. The first digital signal is driven by a first logic agent into a signal line to communicate with a second agent. The second agent is coupled to receive the first digital signal from the signal line. A logic waveform that represents the digital signal is recorded and/or displayed, based upon the crosstalk signal. The technique may also be used for testing simultaneous bidirectional signaling on the same signal line.

Testing for digital signaling

An apparatus and method for debugging a bus including interposing a device that monitors the data transferred between two devices on the bus such that the bus is split into two busses, with data being copied for transmission to a diagnostics device as the data is transferred between the two busses.
