Abstract
In designing a layout of a semiconductor integrated circuit device having a large scale circuit block and logic circuit elements provided together, a power supply connecting line is formed rectilinearly to increase the integration density, reduce power supply noise and achieve automation of layout and interconnection. The semiconductor integrated circuit device includes one large scale circuit block and a plurality of logic circuit elements. VDD and GND annular power supply interconnecting lines are provided to surround the large scale circuit block. The annular power supply interconnecting lines extending in the lateral direction are divided into two lines to be disposed, respectively. Connection of the logic circuit elements and the annular power supply interconnecting lines are made by rectilinear VDD and GND power supply branch interconnecting lines.
