ABSTRACT:
Repeaters are arranged at arbitrary positions to substantially improve transmission speed of a signal. In the semiconductor integrated circuit device1, repeater regions10where repeaters are provided as relay points for wiring are provided in the central parts of the core power source regions2, 3and5, on the left side of the core power source regions4to8and at the upper and lower parts of the semiconductor integrated circuit device1. A power switch region for repeater11is formed so as to surround the core power source regions2to8and the repeater regions10. The power source lines of the reference potential connected to the repeater regions10are laid out at equally spaced intervals throughout the core power source regions2to8, which enables the repeater regions10to be flexibly laid out. This permits the repeaters to be more effectively arranged, which improves the performances of semiconductor integrated circuit device1.
