In this paper, we propose a hybrid hierarchical global router for multi-layer VLSI's, which executes routing and layering simultaneously. This novel approach, a hybrid hierarchical global router, is a combination of a topdown and a bottomup hierarchical routers, and may be one of interesting routing techniques. We also show experimental results, which demonstrate the superiority of the hybrid hierarchical approach. This approach may have many possibilities to be used in a various fields.
