项目摘要

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 systemThe 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 noiseUsing 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.

印刷电路板（PCB）设计支持系统的开发在项目的最后一年完成。并通过实验和仿真研究了噪声行为。 (1)设计支持系统的开发完成了考虑噪声的PCB自动贴装系统的开发。该系统通过使用 Kohoneris 自组织算法和组件分组，自动将组件放置在 PCB 上，同时考虑噪声。为了验证所开发系统的有效性，制造了 PCB 并测量了近场和远场辐射。由于与不考虑噪声的其他方法设计的PCB相比，该系统设计的PCB的辐射有所降低，因此系统的有效性得到了肯定。(2)近场和远场噪声关系的研究利用一个简单配置的PCB，其中有一些IC和电源地走线，测量了电源地走线的输入阻抗、近场和远场噪声。通过测量研究这三个测量值之间的关系。这一结果也通过 EMC 仿真进行了研究。根据这一结果制定了一些EMC规则。通过这些研究，已经完成了考虑EMC规则S的电气电子设备设计支持系统的原型。如果将更有效的EMC规则集成到系统中，该系统就可以用于实际案例。
