ABSTRACT:
An improved semiconductor integrated circuit and power supply wiring designing method and system is described in which the wiring resources have been effectively used without oppressing the same. The semiconductor integrated circuit in accordance with the present invention comprising: a semiconductor chip; an integrated circuit formed within the semiconductor chip; a first power supply pad; a first power supply wiring having a cyclic pattern formed on the integrated circuit for the purpose of supplying power to the integrated circuit from the first the power supply pad; a second power supply pad; and a second power supply wiring having an acyclic pattern formed on the integrated circuit for the purpose of supplying supplementary power to the integrated circuit from the second power supply pad. Particularly the second power supply wiring is connected to the second power supply pad in a binary tree fashion in order to maintain a voltage drop under a required level of each region of the integrated circuit as defined by the first power supply wiring.
