PROBLEM TO BE SOLVED: To recognize signal integrity objectively without generating a mistake by a human being in fault-freedom verification support of a printed board. SOLUTION: An oscilloscope 2 brings a probe 4 into contact with a wire as a target of a measured printed board 1, and a signal waveform b in the wire is observed. A waveform extracting device 5 creates data for real machine waveform simulation converted into data type with a waveform simulation tool based on the signal waveform. A personal computer 3 has a simulation analysis tool for waveform observation, analyzes the data for real machine waveform simulation, and recognizes the signal integrity of the measured printed board. VGA waveform image data is used as a signal waveform, and the waveform printed by the printer is used as data read by a scanner. COPYRIGHT: (C)2006,JPO&NCIPI
