Abstract
A method establishes an initial voltage in a ring oscillator and a logic circuit of an integrated circuit device. Following this, the method enables the operating state of the ring oscillator. After enabling the operating state of the ring oscillator, the method steps up to a stressing voltage in the ring oscillator. The initial voltage is approximately one-half the stressing voltage. The stressing voltage creates operating-level stress within the ring oscillator. The method measures the operating-level frequency within the ring oscillator using an oscilloscope (after stepping up to the stressing voltage).
