1. A method for adjusting propagation delay of each path in an integrated circuit, comprising:
determining, in a worst-based mode, whether a propagation delay of a selected path exceeds a timing requirement;
determining, in a path-based mode, whether the propagation delay of the selected path exceeds the timing requirement; and
when the selected path does not exceed the timing requirement in the path-based mode, lowering a cell delay in the worst-based mode of each cell in the selected path, wherein the step of lowering the delay in the worst-based mode of each cell in the selected path further comprises:
lowering a maximal cell delay in the worst-based mode of each cell in the selected path.
