Abstract
A design support apparatus for semiconductor devices that is used to quickly arrange a non-logic cell for reducing electromagnetic radiation from a semiconductor device at the time of designing it. In this design support apparatus for semiconductor devices, a layout section does a layout for logic cells and wiring patterns to connect the logic cells. An arranged site detecting section detects an arranged site, being a site which contains neither the logic cells nor a prohibited area, after a layout is done by the layout section. A non-logic cell pattern store section stores non-logic cell patterns. A prohibited area containing site detecting section detects a prohibited area containing site, being a site which only contains a prohibited area. A non-logic cell arranging section arranges non-logic cells on the arranged site. Furthermore, the non-logic cell arranging section compares the arrangement of the prohibited area on the prohibited area containing site with a non-logic cell pattern and arranges non-logic cells only on a site where these do not conflict with each other.
