Then based on IACS, we implemented aswitchbox router in which ants attracted by pins and coordinated by stop-to-waitmechanism can avoid routing conflict affectively and route all nets quickly whileoptimize total wire length and vias.

• 在开关盒布线中，各蚁群在各自线网引脚的牵引下，在停等机制的协调下，能有效地避免它们在争用布线区域中引起的冲突，使算法能快速将各线网布通，同时优化了线长和通孔数。
