    摘要： PROBLEM TO BE SOLVED: To provide a method and circuit for supervising execution of a given function or operation of an electronic circuit.
    SOLUTION: The method for supervising a digital signal (EN) includes the steps of: bringing a first P-channel MOS transistor (P1) into a deteriorated state of a negative bias temperature instability (NBTI) type during a period of time in which the signal to be supervised is in a first state; measuring a first amount (VMES) representing a saturation current of the first P-channel MOS transistor (P1) when switching the signal to be supervised into a second state; and giving a detection signal (DET) indicative of a supervisory result when the first amount exceeds a threshold (TH).
