摘要

球栅阵列封装将I/O引脚按栅格排列，实现了芯片与印刷电路板之间的多种连接，但手工布线费时。我们提出了一种2层球栅阵列封装的快速布线方法，以支持设计人员。该方法将钢丝均匀分布在顶层，通过分配迭代改进，提高了网的完成率。

Routability driven modification method of monotonic via assignment for 2-layer Ball Grid Array packages

Ball grid array packages in which I/O pins are arranged in a grid array pattern realize a number of connections between chips and a printed circuit board, but it takes much time in manual routing. We propose a fast routing method for 2-layer ball grid array packages to support designers. Our method distributes wires evenly on top layer and increases completion ratio of nets by improving via assignment iteratively.
