Abstract(in English) | A BGA package realizes a lot of connections between a chip and a printed board. The quality of routing design obtained by manual is high, but it takes much time since it must take a lot of constraints into account. For example, vias must be arranged in appropriate positions so that they connect high-density routings between different layers while avoiding obstacles. Therefore, BGA package routing automation is required in industry. In this paper, we propose a detail via arrangement method that derives detailed routing patterns that satisfy the design rule of both layers from global routing patterns. Our proposed method is based on a dynamic programming. We show that our proposed method obtains an optimum detail via arrangement in almost linear time in terms of the number of rows of vias. |
