An Efficient Rectilinear Steiner Tree Algorithm for Vlsi Global Routing
As we move to deep sub-micron designs below 0.18 microns, the delay of a circuit, as well as power dissipation and area, is dominated by interconnections between logical elements (i.e. transistors)[1]. The focus of this paper is on the global routing problem. Both global and channel routing are NP-hard[2]; therefore, all existing solution methodologies are heuristics. The main aim is to develop...
متن کاملEmbedding into Rectilinear Spaces
We show that the problem whether a given finite metric space (X, d) can be embedded into the rectilinear space R m can be formulated in terms of m-colorability of a certain hypergraph associated with (X, d). This is used to close a gap in the proof of an assertion of Bandelt and Chepoi [2] on certain critical metric spaces for this embedding problem. We also consider the question of determining...
متن کاملA simple linear algorithm for computing rectilinear 3-centers
Rectilinear k-centers of a finite point set P R2 are the centers of at most k congruent axis-parallel squares of minimal size whose union covers P. This paper describes a linear time algorithm based on the prune-and-search paradigm to compute rectilinear 3-centers. The algorithm is elementary in the sense that it does not build on any sophisticated data structures or other algorithms, except fo...
متن کاملAn Exact Rectilinear Steiner Tree Algorithm
Given a set of terminals in the plane, a rectilin-ear Steiner minimal tree is a shortest interconnection among these terminals using only horizontal and vertical edges. We present an algorithm that constructs a rectilinear Steiner minimal tree for an input terminal set. On a workstation, problems involving 20 input terminals can be solved in a few seconds, and problems involving 30 input termin...
متن کاملA shape grammar interpreter for rectilinear forms
Shape grammars play an important role in a new generation of tools for the analysis and design of products. Up until now there has been numerous attempts to create a general shape grammar interpreter, but most of the existing tools are either very specific in their purpose, have only limited functionality or were programmed for one operating system. In this work we present a tool named Shape Gr...
