BoxRouter2.0 is a new global router for ultimate routability.
It is inspired by BoxRouter , but can perform multi-layer routing with 2D
global routing and layer assignment. The 2D global routing is equipped with
several ideas: such as robust negotiation-based A* search for routing
stability, and topology-aware wire ripup for flexibility and so on. After 2D
global routing, 2D-to-3D mapping is done by the layer assignment which is
powered by progressive via/blockage-aware integerlinear programming.

Experimental results show that our global router has better routability with comparable wire-length than other routers on ISPD07 benchmark , and it can complete (no overflow) the widely used ISPD98 benchmark for the first time in the literature with the shortest wire-length. The number quoted below is based on ICCAD 2007 paper .
