Claim 8:
9. The method of claim 1, further comprising:
observing, by the internal lockstep monitor, states of internal signals of a further checker processor of the system circuitry operating in lockstep with the master processor and the checker processor;
comparing, by the internal lockstep monitor, corresponding observed states of the further checker processor, the master processor, and the checker processor; and
when any of the corresponding observed states differ:
triggering, by the internal lockstep monitor, the master tracer to output stored master trace data recorded from the output of the master processor; and
triggering, by the internal lockstep monitor, the checker tracer to output stored checker trace data recorded from the output of the checker processor.
