Abstract
A leakage current analyzing apparatus receives input of data used for analysis and indicating intra/inter-chip variation concerning the gate length of transistors constituting cells in a circuit to be designed, where the inter-chip variation is handled as a discrete probability density distribution R. Using the data input, the leakage current analyzing apparatus obtains a cumulative probability density for a leakage current value (of the circuit) that is equal to or less than each arbitrary leakage current value Ito I. As a result, the leak rate of the circuit to be designed can be correctly obtained without limiting the shape of distribution.
