Operation check support device and operation check support method

摘要

A device that supports an operator in checking an operation of an electronic circuit mounted on a board includes the following units. A waveform obtainment unit obtains a measured waveform as a signal waveform of a voltage or current measured by the operator bringing a probe into contact with the board. A similarity calculation unit calculates a similarity between the measured waveform and each of simulated signal waveforms which are signal waveforms of a voltage or current at respective nodes on the electronic circuit and are obtained by simulating the operation of the electronic circuit. A position determination unit determines, based on node information indicating positions of the nodes, a node position on the electronic circuit which corresponds to a simulated signal waveform having a maximum similarity. A notification unit notifies the operator of the node position determined on the electronic circuit.

1. An operation check support device that supports an operator in checking an operation of an electronic circuit mounted on a board, the operation check support device comprising:
a waveform obtainment unit configured to obtain a measured waveform that is a signal waveform of one of a voltage and a current, the measured waveform being measured by the operator bringing a probe into contact with the board; a similarity calculation unit configured to calculate a similarity between the measured waveform obtained by the waveform obtainment unit and each of simulated signal waveforms, the each of simulated signal waveforms being a signal waveform of one of a voltage and a current at a corresponding one of nodes on the electronic circuit, and the each of simulated signal waveforms being obtained by simulating the operation of the electronic circuit; a position determination unit configured to determine a position of a node among the nodes on the electronic circuit based on node information, the node corresponding to a simulated signal waveform having a maximum similarity calculated by the similarity calculation unit, the node information indicating positions of the nodes on the electronic circuit, and the nodes each corresponding to a corresponding one of the simulated signal waveforms; and a notification unit configured to notify the operator of the position of the node on the electronic circuit as determined by the position determination unit.
