Abstract :
The EMC-constraint CAD layout support tool was developed for the manual printed circuit board design. In the developed system two possible constraints; signal reflection and crosstalk, were considered. The former was taken into account in the element placement stage and the latter was considered in the routing stage. The reflections and crosstalk noise are first calculated for all combinations of the parameters. And the constraints to the line length and space are indicated to the designer in the manual layout routing stage. The tool can help the layout designer interactively and visually. In this paper the system configuration of the support tool and its applications are demonstrated
