Abstract: An electromagnetic pulse detector in an integrated circuit includes one or more peak hold circuits coupled to one or more traces in the integrated circuit and configured to asynchronously detect voltage spike(s) on the one or more traces and store voltage value(s) corresponding to the voltage spike(s). One or more comparator circuits are coupled to the peak hold circuits to compare the voltage values corresponding to the voltage spikes to one or more threshold voltage values. Storage locations are coupled to the comparator circuits to store indications of the voltage spike(s) being greater than the threshold voltage value to thereby indicate detection of an electromagnetic pulse.
