Abstract
A method for timing optimization is disclosed. The method includes obtaining information on timing of paths in a chip, wherein the information includes a mean of slacks and a sigma of slacks of each of the paths, determining a sigma margin (SM) value each of the paths, the SM value being obtained by dividing the mean by the sigma, and determining that a first path of the paths is more critical than a second path of the paths, an SM value of the first path being smaller than that of the second path.
