Abstract
A speed monitor circuit integrated in an integrated circuit (IC) determines the speed of the IC. The speed monitor circuit includes an oscillator that generates an oscillator signal. A speed determining circuit generates a first count based on transitions of the oscillator signal. A match signal corresponds to the speed of the oscillator based on the first count and a reference count.
