Parallel bus debugging tool

摘要

A system and method for testing the signals on a parallel communication bus uses a single printed circuit board that connects to the bus. The signals from the bus may be passively and actively filtered prior to a multiplexer. The multiplexer may be controlled by a variety of inputs, including communications over a second bus by a remote device. The output of the multiplexer is one or more probe points that may be connected to a measurement device.
