为了解决老化预测传感器中存在软错误问题,采用在老化预测传感器的延迟单元加入C单元的方法。模拟老化预测传感器受到外界干扰并引起软错误的情况,检测传感器的性能。老化预测传感器能够抑制软错误引起的电路失效问题,同时不影响老化预测传感器预测老化的功能,并且相对于其他传感器的稳定性检测器部分面积开销减少了18.75%。
In order to solve the problem of soft errors and area in the aging problem, method for adding a C unit in the delay element in the aging prediction sensor was adopted.The situation of aging prediction sensor disturbed by external disturbance and induce mistakes was simulated and sensor performance was detected.The aging prediction sensor can restrain the circuit failure caused by soft errors, and it does not affect the aging prediction of the aging point of the function of the sensor at the same time, stability detector part area expenditure is reduced by 18.75% compared to the other sensors.
