Abstract: A method of verifying operation of an oscillator includes performing a Monte-Carlo simulation with respect to points in an initial-conditions space, and then judging whether a frequency error exists. An oscillation error is determined to exist when the frequency error exists. Additional operations include determining a point at which a probability of having a settling time longer than a maximum value, of a settling time obtained up to a present time, is maximum when the frequency error does not exist. The Monte-Carlo simulation is then performed on the determined point to judge whether the frequency error exists.
