<P>PROBLEM TO BE SOLVED: To solve the problem that a capacitor corresponding to the frequency characteristics of a circuit is not appropriately arranged, and that it is difficult to design a semiconductor device which is high in power supply noise resistance, and that it is necessary to insert much more capacitor cells in order to satisfy a necessary capacity. <P>SOLUTION: A design support device 1 of a semiconductor device includes: a load capacity value calculation part 103 for, on the basis of arrangement/wiring information 201 of an LSI and delay library information 202 comprising the delay element of the LSI, calculating the load capacity value of each logical cell arranged in the LSI; and a decoupling capacitor arrangement part 104 for, on the basis of the load capacity value calculated by the load capacity value calculation part 103, determining the frequency band of each logical cell, and for arranging a capacitor having frequency characteristics corresponding to the determination result in the empty area of the peripheral section of the logical cell as the object of the arrangement of the capacitor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
