Abstract

PURPOSE:To obtain a computer functional cell for which an optimum power supply can be designed even if it is arranged at any position and which operates stably without being affected by other cells adjacently arranged by a method wherein the computer functional cell is surrounded with a wiring aluminum which is constant in width and whose potential is made equal to that of a power source. CONSTITUTION:A standard cell system integrated circuit is provided with a computer functional cell 13 as a component cell, and the functional cell 13 is surrounded with wiring aluminum 11 and 12 whose potential are made equal to that of a power source potential. For instance, the first layer wiring aluminum 11 connected to a power source VDD and a first layer wiring aluminum 12 connected to a ground VSS are provided to the periphery of the computer functional cell 13, and a data bus line 14, other standard cells 15 and 16, and others are provided outside the wiring aluminum 11 and 12. By this setup, a computer functional cell can be easily supplied with a power from any place and an optimum power supply can be designed even if standard cells and wirings adjacently arranged change in condition. And, the computer functional cell can be prevented from being affected by the adjacent standard cells and the wirings, so that it can be kept stable in property.
