ABSTRACT:
A method of determining which of a plurality of electrical devices connected to a node of a circuit under test is causing a failure at that node by causing individual devices to drive the node one device at a time, taking passive voltage measurements at the node at separate times when individual devices are controlled to drive the node, and analyzing measured voltages resulting when different devices are driving the node to identify which is causing the failure.
