摘要：
A design supporting method includes partitioning a partition path of circuit information into partitioned paths based on a given condition, calculating a variation value of each of the partitioned paths based on variation values on a delay of a cell included in the corresponding partitioned path, calculating a partition propagation delay time of each of the partitioned paths based on the variation value of the corresponding partitioned path, and calculating a source propagation delay time of the source path by merging the propagation delay time of each of the partitioned paths.
