ABSTRACT:
A layout device includes a processing type setting part for classifying a layout of a semiconductor integrated circuit in every area in accordance with the percentage voltage drop in the circuit, and for extracting a processing target portion composed of a group of areas, including an area having a percentage voltage drop exceeding a predetermined threshold; a layout generating part for applying layout change processing to alleviate differences of the percentage voltage drops among the areas for circuit components, such as power supply wiring and connecting points in the processing target portion.
