ABSTRACT:
A system and a method for testing the integrity of interconnection networks on a circuit board or substrate are disclosed. To test the continuity of a being tested network, two probes are used. To test the integrity of the being tested network, as it relates to other nets on the circuit board, a rectangular pulse is provided to the being tested network, and a signal in response to the stimulus pulse, provided across an external capacitor and resistor connected to the reference plane of the circuit board or substrate, is sampled by a transient analyzer. The leading edge of the thus sampled response signal provides an indication of whether the being tested net is acceptable, opened, shorted, or has a high leakage resistance to another net.
