Abstract
A method of identifying potential clock qualifiers in netlist description of an integrated circuit, the netlist comprising logic elements. The method comprises the steps of initializing every net of the netlist to a speed of zero, identifying all potential clock nets so that all signals with a path to a clock source has a speed of one, computing the maximum speed of each output net of each of the logic elements in the netlist, and marking as a potential clock qualifier any net of the netlist that is input to the logic elements in the netlist that is slower than the maximum speed of any net that is input to the logic elements.
