Abstract

A design support system 100 according to the present invention comprises: an LSI library 10, in which rated characteristics of various LSIs are stored by an LSI library preparation unit 70; a decoupling capacitor library 20, in which rated characteristics of various capacitors are stored; a PCB library 30, in which the cross-sectional structures of various power wiring lines are stored; a decoupling capacitor search unit 40, for employing the LSI library 10 and the decoupling capacitor library 20; a power wiring determination unit 50, for employing the results obtained by the decoupling capacitor search unit 40, the LSI library 10 and the PCB library 30; and a design results output unit 60, for outputting the results received from the power wiring determination unit 50. Furthermore, the data in the three libraries can be updated or new data can be added.
