ELECTRONIC CIRCUIT DEVICE, FAILURE DIAGNOSTIC DEVICE, FAILURE DIAGNOSTIC SYSTEM, AND FAILURE DIAGNOSTIC PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an electronic circuit device, a failure diagnostic device, a failure diagnostic system, and a failure diagnostic program, to accurately diagnose a failure.

SOLUTION: The failure diagnostic system comprises a model generation device having a model generation means for generating a model in which a failure cause in a partial program designed to constitute an entire program describing a processing procedure to be executed by an electronic circuit device is associated with a trouble caused by the failure cause based on a causal relation determined by design; and a failure diagnostic device having a failure diagnostic means for diagnosing a failure caused in the electronic circuit device for executing the entire program by use of the model generated by the model generation device. According to this structure, a failure caused in the electronic circuit device for executing the entire program can be accurately diagnosed based on the causal relation determined by the design of the entire program.
