1. A computer-readable recording medium storing therein a delay analysis support computer program that supports analysis of delay in a target circuit that includes a plurality of cells and causes a computer to execute: acquiring error information concerning a cell-delay estimation error that is dependent on a characterizing tool that estimates cell delay; calculating, based on the error information and a first probability density distribution that concerns the cell delay of each cell and is obtained from the cell delay estimated by the characterizing tool, a second probability density distribution that concerns the cell-delay estimation error of each cell; and linking the second probability density distribution and a cell library storing therein the first probability density distribution.
