This paper presents a new model for VLSI routing in the presence of obstacles and boundary. A new approach for reduction of the routing area is proposed, and a modified Lee algorithm - weighted Lee algorithm is applied on the extended Hanan grid to compute sub-optimal RSMT in $O(n^2(n+m)^2\log(n+m))$ time, where $n$ is the number of terminals, $m$ is the number of vertices of obstacles and boundary.
