CIRCUIT PERFORMANCE EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To improve estimation accuracy by taking into account a correlation of performance between interconnects or elements in calculating delay distribution of an integrated circuit. SOLUTION: Circuit information 11, performance distribution information 12 of the interconnects or elements in the integrated circuit, and correlation information 13 of performance between the interconnects or elements are inputted (S11). A vertex is selected for calculation (S12), and a correlation between delay distribution at the selected vertex and delay distribution in a partial circuit including the selected vertex is calculated based on the performance distribution information 12 and the correlation information 13 (S13).
