A Novel Multilayer Gridless Detailed Routing Method
Based on a non-uniform-grid graph model, a self-adaptive iterative algorithm is presented for multi-layer gridless area routing. The algorithm can not only handle the case in which the number of metal layers is uncertain, but also greatly reduce the search space of multi-layer maze routing by converting multi-layer into multiple two-layer pairs. General speaking, the maze routing is slow. In order to accelerate checking the routing feasibility of a point in maze routing,an improved binary internal tree is introduced to manage routing obstacles, by which the comparison times are reduced.
