Abstract

PURPOSE: To realize a diagnostic system where diagnosis for every replacement unit is possible and development of diagnostic test is easy.
CONSTITUTION: In case that package A is diagnosed, test data is scanned in to input signal receiving circiut 2-1 of A, and clock signals are supplied from control circuit 5 to all latches including the input signal receiving circuit of A and input signal receiving circuits 2-2 to 2-4 of packages B to D connected to the output A, and they are operated. Then, the result is scanned out and is compared with a normal response obtained previously to decide whether a fault exists or not. At this time, clock signals are not supplied from the control circuit to circuits other than input signal receiving circuits of other packages. When existence of the fault is confirmed, a diagnostic dictionary is indexed to indicate the faulty package.
