Abstract

Semiconductors
A system diagnosis technique for multichip module (MCM) ispresented. The proposed technique uses built-in probes for monitoringinternal responses and, with a signature analysis scheme based onerror correcting codes, identifies the probes where erroneous test responses have been detected. Conceptsfrom system diagnosis is used in conjunction withsignature analysis in developing the proposed MCM diagnosistechnique, where the resulting patterns of the faulty probes are usedin the identification of the faulty submodules (dies). The proposedtechnique offers a diagnostic capability in system functional test.[PUBLICATION ABSTRACT]
