Method for establishing aging model of device and analyzing aging state of device with aging model
A method for establishing an aging model of a device is provided. The device is measured to obtain degradation information of the device under an operating condition, wherein the device is a physical device. The degradation information is partitioned into a permanent degradation portion and an impermanent degradation portion. The impermanent degradation portion is differentiated by time to obtain a differential value. The aging model is obtained according to the differential value. When the differential value is greater than zero, a degradation of the device increases over time, and when the differential value is less than zero, the degradation of the device decreases over time.
