Abstract:
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.
