PURPOSE:To verify the fault analyzing function without waiting for the corresponding between a scan-in address for generating a dummy fault and a fault correct answer value as to the method which verifies the fault analyzing function of the SVP from trace information of a fault analysis detected by the hardware. CONSTITUTION:A host 1 executes a program, the dummy fault is put in by scanning-in operation from the SVP 2 according to an indication from the host 1, and fault information (latch numbers of fault propagation destinations from a fault source latch number and their quantity) is gathered by the SVP 2; and the latch at the fault source is traced from the gathered fault information based on the analytic dictionary 22 wherein the propagation paths of respective fault latches are previously registered to judges that the fault analyzing function of the SVP 2 is normal when fault information is fault trace and when fault information less than fault trace, or output an error message as a deficiently of generated information in the analytic dictionary 22 if an analysis of the fault is completed without tracking all the gathered fault information in case of a deficiency in analytic information in the analytic dictionary 22. |
