ABSTRACT:
A network sensitive pulse generator circuit and a method of using the circuit to quickly detect faults in a net under test are described. The novel circuit generates pulses which depend upon the transient behavior of the net under test. The stimulation of the net and the sensing of the net's response operate responsively to a feedback signal, which is also a signature signal. By connecting the net under test to the novel circuit, the combination of the novel circuit and the net under test generates a series of output pulses. The number of pulses generated in a predetermined period of time forms the signature of the net under test. A preferred embodiment is described which uses differential amplifiers to stimulate the net and to sense the net's response. The differential amplifier which senses the net's response is connected to a circuit which produces the feedback/signature signal. The feedback/signal is then provide to the differential amplifiers to adjust their behavior.
