| Research Abstract |
The development of the design support system for printed circuit board (PCB) was finished in this last year of the project. Furthermore a noise behavior was studied with experiment and simulation.
(1) Development of design support system
The development of the auto placement system of a PCB with noise consideration was finished. This system automatically places the components on a PCB with noise consideration by using the Kohoneris self organization algorithm and a grouping of the components. In order to verify the effectiveness of the developed system, PCB was manufactured and near and far field radiations was measured. Since the radiaticn was reduced from the PCB designed by the system comparing to the PCB designed by other method without noise consideration, the effectiveness of the system was certained.
(2) Study on a relation between near and far field noise
Using a simple configuration PCB which has some IC and power-ground trace, input impedance of the power-ground trace, near field and far field ware measured. From the measurement the relationship between these three measured values was studied. This result was also investigated bythe EMC simulation. Some EMC rules are developed about this result.
From these studies, a prototype of the design support system for electric and electronic equipment considering EMC rule S has been accomplished. If more effective EMC rules are integrated into the system, the system can be used for practical case.
