Abstract

Technological advances such as flip-chippackaging, multiple hierarchical wiring planes, andultra-high frequencies reduce the effectiveness ofconventional diagnostic techniques. It has recently beendemonstrated that light pulses emitted during circuitswitching can be used to characterize the behavior ofintegrated circuits. In this paper, a new method of circuitcharacterization using this technique is described. Anexample of the diagnosis of a timing failure caused by aresistive path to a single transistor is described.
