ABSTRACT:
A fault-diagnosing apparatus and method for an electronic computer designed to diagnose a fault occurring in constituent circuits formed of a plurality of packages according to a signal denoting the status of a sequential circuit in the selected one of the packages, which comprises a fault-diagnosing unit for diagnosing a fault occurring in any of the sequential circuits; an exclusively fault-diagnosing circuit provided in the respective packages; and a common exclusively fault-diagnosing bus to which the output terminals of said exclusively fault-diagnosing circuits are jointly connected, and wherein the exclusively fault-diagnosing circuit sends forth to the exclusively fault-diagnosing bus signals denoting the interior status of the sequential circuit included in the package selected by the fault-diagnosing unit; and the fault-diagnosing unit diagnoses a fault occurring in any of said sequential circuits from the signal received through the bus.
