PURPOSE:To improve the point-out accuracy of a trouble position by extracting previously the data on the circuit state via a trouble analyzing subject computer, performing the logical simulation based on the extracted data on the circuit state, ad comparing the obtained circuit state of a normal mode with the circuit state of a trouble mode. CONSTITUTION:A trouble detecting computer system contains the trouble analyzing subject computers 1 - 3 connected to a single trouble analyzing computer 4. The circuit states of computers 1 - 3 are extracted and stored for each prescribed time, and the due processing is started at occurrence of troubles of computers 1 - 3. Then a logical simulator 15 performs the logical simulation of the circuit states of the computers 1 - 3 based on the stored circuit states set before occurrence of the trouble. A comparison processing part 14 compares successively the simulated circuit states with those of the stored ones. Based on these comparison results, the trouble positions of the computers 1 - 3 are pointed out. |
