发明名称 SYSTEM AND METHOD FOR MEASURING AN INTEGRATED CIRCUIT AGE
摘要 A system and method are provided for measuring an integrated circuit age. A first clock generator is provided for generating a first dock signal. Additionally, a second clock generator is provided for generating a second clock signal. Further, a phase detector is provided that is in communication with the first dock generator and the second dock generator. The phase detector is operable for receiving the first clock signal from the first clock generator and the second clock signal from the second dock generator, and outputting a phase difference signal. Still yet, a circuit is provided that is in communication with the phase detector and the first clock generator. The circuit is operable for receiving the first clock signal from the first clock generator and the phase difference signal from the phase detector. The circuit is further operable for synchronizing the phase difference signal from the phase detector with the first dock signal from the first clock generator. Moreover, the phase difference signal is capable of being used as a measure of an integrated circuit age.
