摘要： Methods and systems are provided for determining efficacy of stress protection circuitry. The methods and systems employ a ring oscillator that models at least one parameter of a functional circuit to be protected by the stress protection circuit. A stress signal is applied to the ring oscillator and parametric degradation is measured to determine the effectiveness of the stress protection circuit in protecting the ring oscillator. A stress signal can be a voltage or current that stresses the normal operation of a functional circuit. The parametric degradation of the ring oscillator can be correlated to the parametric degradation that would be experienced by the functional circuit.
