NTHU-Route 2.0 is a fast and stable global router. It improves the solution quality and runtime of NTHU-Route by the following enhancements:
1. a new history based cost function,
2. new ordering methods for congested region identification and rip-up and reroute, and
3. two implementation oriented techniques.
At the ISPD 2008 Global Routing Contest, NTHU-Route 2.0 generated the best solutions for 11 of 16 benchmarks among all participating global routers and won the 1st place.
