Method for testing noise immunity of an integrated circuit and a device having noise immunity testing capabilities

Abstract

A method for testing a noise immunity of an integrated circuit; the method includes: determining a value of a power supply noise regardless of a relationship between the power supply noise value and a phase sensitive signal edge position resulting from an introduction of the power supply noise; receiving, by the integrated circuit, a phase sensitive signal; introducing jitter to the phase sensitive signal by a circuit adapted to generate a substantially continuous range of power supply noise such as to alter edges position of the phase sensitive signal; providing the jittered phase sensitive signal to at least one tested component of the integrated circuit; and evaluating at least one output signal generated by the at least tested component to determine the noise immunity of the integrated circuit.
