135-degree PCB area routing method based on dynamic mesh

ActiveCN115270693BOptimize routabilityImprove wiring qualityCAD circuit designConstraint-based CADDistributed computingIndustrial engineering
This invention discloses a 135-degree PCB area routing method based on dynamic mesh. First, a serial routing priority queue is constructed to determine the routing order of each net. Then, onboard components and PCB bounding boxes are stored in an obstacle list as basic obstacles for each layer of routing. Next, a dynamic mesh is constructed based on the starting pin position of the net and the obstacles. The constituent elements of the edges in the constructed dynamic mesh are analyzed to obtain the non-obstacle edges. For non-uniform segmentation of channels, the center point of each segment is set as a candidate node for routing and added to the candidate list. An improved heuristic algorithm is used to find the node with the lowest estimated cost. A 135-degree mapping scheme is executed based on the real-time constructed dynamic mesh. Finally, for nets that cannot be extended to the endpoint, a rewiring mechanism is used to adjust existing lines, further improving routing quality.
