1. A method of predicting a delay of at least one critical path of an integrated circuit, the method comprising:

  • determining a delay of at least one ring oscillator on the integrated circuit; and

    calculating a predicted delay for the at least one critical path delay based on a delay of components of the critical path at a corner condition, a wire delay of the at least one critical path, a delay of the at least one ring oscillator at a corner condition, and the determined delay of the at least one ring oscillator.
