Abstract
A method and apparatus are provided for ensuring that a clocked circuit will function after fabrication, regardless of the presence of clock skew. More particularly, a method and apparatus are shown for de-skewing the clock signals of such a clocked circuit only when clock skew is present. When such clock skew does not develop, peak performance of the associated circuit can be achieved by turning off the de-skewing function without removing that functionality from the circuit.
