Abstract:
1. A non-transitory computer-readable recording medium storing therein a leakage current analyzing program that causes a computer to execute: acquiring a probability density distribution that represents a first variation component specific to each cell in a circuit to be designed and concerning a gate length of a transistor constituting a cell, and a discrete probability density distribution that represents a second variation component common to all the cells of the circuit and concerning the gate length; calculating, based on the probability density distribution and the discrete probability density distribution acquired at the acquiring and a function model that expresses leakage current variation of a cell as a product of the first variation component and the second variation component, a cumulative probability density for a leakage current value of the circuit, the leakage current value of the circuit being less than or equal to an arbitrary leakage current value; and outputting, for each arbitrary leakage current value, the cumulative probability density calculated at the calculating.
