Abstract:
1. An electrical integrity testing apparatus for testing electrical integrity of a plurality of nets on a circuit under test, comprising: one or more signal generators each operable to generate a respective known oscillating digital reference signal; a plurality of stimulating probes each couplable to receive one of the respective known oscillating digital reference signals and couplable to a respective first end of a corresponding net on the circuit under test; a plurality of capacitive sensing probes each operable to capacitively sense a respective signal from a respective second end of a corresponding net that is stimulated by one of the plurality of stimulating probes; and a signal correlator which performs signal correlation between each respective capacitively sensed signal sensed from a corresponding one of the plurality of nets and the respective known oscillating digital reference signal used to stimulate the corresponding one of the plurality of nets.
