摘要

PPROBLEM TO BE SOLVED: To analyze network capacity in a logic circuit with high accuracy by estimating wiring length with high accuracy. PSOLUTION: A first storage device (44) for storing layout data (51) and an operation processor (45) for creating a library (52) for predicting network capacity on the basis of the layout data (51) and storing the network capacity in a second storage device (44) constitute a library creating device. Here, the operation processor (45) calculates the scales of logic cones (4) and (5) on the basis of the logic cones (4) and (5) being combination circuits that form a signal path in which a signal is transmitted from (FF3) of an input stage (2) of the network to (FF4 and FF5) of an output stage (3) of the network. A table (56) obtained by associating the capacity of the network with the scales of the logic cones (4) and (5) and with the fanout (F/O) of the network is generated and stored in the library (52).
