issues in global routing
In this paper, we present several shortcomings of current global routers and propose enhancements to remedy the problems. We propose that global routers incorporate aspects of both placement and detail routing in order to improve the quality of the global routing. In addition, we propose the use of a constrained die methodology to complement fixed and variable die design flows. This paper outlines the algorithms present in the commercial global routers available for InternetCAD.com, Inc.
