Abstract
A system and method for changing a circuit design are described. The method includes generating a propagation graph for the circuit design and estimating slack values for some of the paths in the propagation graph. The method also includes making a virtual change to the circuit design and determining whether to accept or reject the change based on how the change affects the estimated slack values.
