Abstract: Systems and methods are provided for an automated analog fault injection including creating a list of fault models for injection to an analog circuit, adding a first fault placeholder to the analog circuit, running fault simulations by replacing the first fault placeholder with a first fault model from the list of fault models, and determining whether the first fault model is detected.

Abstract: Automatic power saving for decreasing power demand during a power interruption while maintaining the appearance of full operation of a signal processor including predefined power consuming circuits, a communications interface, and a state machine includes sensing when a power supply interruption has occurred, providing a clock signal, halting the clock signal to the predefined power consuming circuits during a power interruption; and continuing to provide a clock signal to a communications interface regardless of a sensed interruption for maintaining the appearance of normal operations during the sensed interruption.
