Abstract

Double-layer printed circuit board(PCB) usually has the complex spatial structure and the routing pattern, and many constraint rules. However, in the past researches, the spatial structure of PCB is simple and the routing pattern is single, and the spatial relationship and topological information of PCB can not be effectively used to guide the routing. In order to make up for the shortcomings of the previous work, this paper proposed a spatial subdivision algorithm based on geographic information system(GIS) technology. Firstly, it used the spatial distance and the topological relationship of the geometric elements for group preprocessing. Then it introduced the vector and grid model to construct the network model under the complex space and attribute constraints. Based on the network model, it extracted the regional reference line, and used the spatial buffer technology to obtain the spatial subdivision result for guiding the routing. Experimental results show that the proposed algorithm can achieve 100% routing connectivity under the condition that all design rules are met, and effectively utilize routing space resources. The routing shape of the proposed algorithm is close to manual routing, which is of practical significance to realize the automatic routing of double-layer PCB under complex scenes and multi-constraints.
