Abstract
Power-glitch detection and power-glitch self-testing within a chip is shown. In a chip, a processor has a power terminal, a glitch detector, and a self-testing circuit. The power terminal is configured to receive power. The glitch detector is coupled to the power terminal of the processor for power-glitch detection. The self-testing circuit has a glitch generator and a glitch controller. The glitch controller controls the glitch generator to generate a self-testing glitch signal within the chip to test the glitch detector.
