Abstract : This report describes the computational techniques formulated to extend the methods of automatically isolating faults in electronic circuitry to the level of a micromodule. The micromodule may consist of a single component or it may itself be a microcircuit consisting of several active and passive components. The techniques developed are oriented towards analog circuits. All circuit equations used in the diagnosis are generated by a digital computer from the specification of the circuit schematic in coded form, and from the nominal values and tolerances of all circuit components. Three (3) diagnostic techniques are implemented. Two of the techniques presented utilize a digital computer to implement the diagnosis, whereas the third technique utilizes precomputed network measurement bands and a manual graphic method for fault diagnosis.
