The traditional detection system has the problems of inaccurate data collection of circuit aging and poor detection effect. In order to solve these problems,a circuit aging detection and prevention system based on gate replacement technology is designed. According to the detection and prevention principles of the circuit aging,the structure diagram of the system hardware was established,and the sensor and voltage-controlled oscillator circuit were designed. The principle of equal precision measurement is used to select the optimal input control vector,set the path protection,identify the key gates,and design the circuit for aging alleviation. The contrast experiment was performed for the prevention and detection of the traditional system and proposed system. The experimental results show that the system has accurate data collection for circuit aging,and perfect detection and prevention effects.
