A Negative Reinforcement Method for PGA Routing
We present an efficient and effective method for the detailed routing of symmetrical or sea-of-gates FPGA architectures. Instead of breaking the problem into 2-terminal net collec...

A Polynomial-Time Approximation Scheme for Weighted Planar Graph TSP
Given a planar graph on n nodes with costs weights on its edges, de ne the distance between nodes i and j as the length of the shortest path between i and j. Consider this as an i...

CDCTree: novel obstacle-avoiding routing tree construction based on current driven circuit model
Abstract— Routing tree construction is a fundamental problem in modern VLSI design. In this paper we propose CDCTree, an Obstacle-Avoiding Rectilinear Steiner Minimum Tree (OARSM...
