ABSTRACT:
A design system, a program, a program product and a design method which can easily design a semiconductor integrated circuit element having a decoupling capacitor are provided. In an element region which serves as an IC chip100, an input/output block110is arranged, and analog-signal-circuit blocks120etc. are arranged. In the capacity insertion regions160etc. of an open region115which does not belong to the blocks, unit capacity cells10aare arranged in a latticed pattern. Analog wiring lines170are arranged between the input/output block110and the analog-signal-circuit blocks120etc., and the unit capacity cells10aof the capacity insertion region160are respectively connected wiring lines171and172of power source and GND potentials by via-conductors173and174. Thereafter, unit cells180are arranged, and wiring lines190for the connections between the unit cells and between the input/output block110and memory blocks140etc. are arranged. Further, the unit capacity cells10aof the capacity insertion regions161etc. are respectively connected to power source and GND wiring lines191and192by via-conductors.
