Routing for high-speed boards is largely a time- consuming manual task today. The ordered escape routing problem is one of the key problems in board-level routing, and Boolean Satisfiability (SAT) based approach [1] is the only solution to this problem so far. In this paper, we first solve the major deficiency of the original SAT formulation so that the escape problem is completely resolved. Then we propose two techniques to extend SAT approach for large-scale problems. Experimental results on industrial benchmarks show that our methods perform well in terms of both speed and routability.
