This paper describes a new fault localization method that is based on the analysis of power supply transient signals. Impulse response functions derived from the power grid are used to de-construct the measured power port transient signals into a set of gate level transients generated by the logic gates as signals propagate along paths in the circuit. By comparing these gate transients with those obtained from a defect-free chip or simulation model, it is possible to identify anomalies produced by defects and to locate them to specific path segments in the layout. Impulse response functions are used to significantly reduce both the attenuation effects of the power grid on the gate-generated transients and the chip-to-chip impedance variations in the power grid and test environment. Non-linear calibration techniques are proposed to reduce the chip-to-chip variations in path delays introduced by process variations. The procedure is demonstrated using simulation experiments to locate the position of defects to one or a small group of gates.
