Download or read book Routing Congestion Analysis and Reduction in Deep Sub micron VLSI Design written by Zion Cien Shen and published by . This book was released on 2004 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Congestion is one of the main optimization objectives in global routing; however, the optimization performance is constrained because the cells are already fixed at this stage. Therefore, a designer can save substantial time and resources by detecting and reducing congested regions during the planning stages. An efficient yet accurate congestion estimation model is crucial to be included in the inner loop of floorplanning and placement design. In this dissertation, we mainly focus on routing congestion modeling and reduction during floorplanning and placement.

Book excerpt: RETHINKING GLOBAL ROUTING FOR MODERN VLSI DESIGN: CONGESTION REDUCTION AND MULTI-OBJECTIVE OPTIMIZATION Hamid Shojaei Under the supervision of Professor Azadeh Davoodi At the University of Wisconsin-Madison The high volume and complexity of cells and interconnect structures are causing serious challenges to routability in modern VLSI design. Several new factors contribute to routing congestion including significantly-different wire size and spacing among the metal layers, sizes of inter-layer vias, various forms of routing blockages, local congestion due to pin density and wiring inside a global-cell, and virtual pins located at the higher metal layers. In addition, interconnects now play a significant role in impacting the performance metrics of a design including power, speed and area. Global routing, as the first stage in which the interconnects are planned, is now of significant importance in determining the performance metrics and the routability of the design. However, the standard model of global routing considers minimization of wirelength with a simplified model of routing resources which ignores these objectives and complicating factors. To address the above challenges, this dissertation has three contributions in rethinking global routing for modern VLSI design. First, we present a framework for congestion analysis for quick prediction of the locations of highly-utilized routing regions. The fast framework is suitable for integration in the design flow, for example as an integration within a routability-driven placement procedure. Second, we offer two contributions in order to estimate and manage the congestion caused by local nets which are ignored in a standard model of global routing. It allows optimizing congestion directly within global routing by treating global and detailed routing in a more holistic manner. In addition, many of the above-mentioned factors contributing to congestion are accounted for in our congestion analysis and optimization framework. Finally, we present a procedure for multi-objective global routing which is able to optimize multiple performance metrics beyond wirelength. The framework is a collaborative one which receives as input multiple global routing solutions created by single-objective procedures.

This book was released on 2022-06-14 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complexity of modern chip design requires extensive use of specialized software throughout the process. To achieve the best results, a user of this software needs a high-level understanding of the underlying mathematical models and algorithms. In addition, a developer of such software must have a keen understanding of relevant computer science aspects, including algorithmic performance bottlenecks and how various algorithms operate and interact. This book introduces and compares the fundamental algorithms that are used during the IC physical design phase, wherein a geometric chip layout is produced starting from an abstract circuit design. This updated second edition includes recent advancements in the state-of-the-art of physical design, and builds upon foundational coverage of essential and fundamental techniques. Numerous examples and tasks with solutions increase the clarity of presentation and facilitate deeper understanding. A comprehensive set of slides is available on the Internet for each chapter, simplifying use of the book in instructional settings. “This improved, second edition of the book will continue to serve the EDA and design community well. It is a foundational text and reference for the next generation of professionals who will be called on to continue the advancement of our chip design tools and design the most advanced micro-electronics.” Dr. Leon Stok, Vice President, Electronic Design Automation, IBM Systems Group “This is the book I wish I had when I taught EDA in the past, and the one I’m using from now on.” Dr. Louis K. Scheffer, Howard Hughes Medical Institute “I would happily use this book when teaching Physical Design.

Download or read book An Artificial Intelligence Approach to VLSI Routing written by R. Joobbani and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Routing of VLSI chips is an important, time consuming, and difficult problem. The difficulty of the problem is attributed to the large number of often conflicting factors that affect the routing quality. Traditional techniques have approached routing by ignoring some of these factors and imposing unnecessary constraints in order to make routing tractable. In addition to the imposition of these restrictions, which simplify the problems to a degree but at the same time reduce the routing quality, traditional approaches use brute force. They often transform the problem into mathematical or graph problems and completely ignore the specific knowledge about the routing task that can greatly help the solution. This thesis overcomes some of the above problems and presents a system that performs routing close to what human designers do. In other words it heavily capitalizes on the knowledge of human expertise in this area, it does not impose unnecessary constraints, it considers all the different factors that affect the routing quality, and most importantly it allows constant user interaction throughout the routing process. To achieve the above, this thesis presents background about some representative techniques for routing and summarizes their characteristics. It then studies in detail the different factors (such as minimum area, number of vias, wire length, etc.) that affect the routing quality, and the different criteria (such as vertical/horizontal constraint graph, merging, minimal rectilinear Steiner tree, etc.) that can be used to optimize these factors.
