Abstract
The present invention discloses an improved wiring method. Grids are defined at a grid-routing step in such a way that a part of predetermined design criteria are met. Wiring routes are decided on the basis of these grids so that they follow the design criteria and plural functional blocks are connected together. When some nets are left in such a manner that they are assigned no wiring routes, their wiring routes are decided at a non grid-routing step following the design criteria, in defiance of the grids but in accordance with the design criteria. If there are still some nets without wiring routes, their wiring routes are decided at a non grid-routing step ignoring the design criteria. Then, some of the already-defined wiring routes are shoved so as to meet each of the design criteria, and individual wiring patters are generated with respect to all of the decided wiring routes in such a manner that the criteria are met. Even if a greater amount of wiring must be carried out within a smaller area, generation of required wiring patterns can be completed in a short time.
