Download or read book Period and Glitch Reduction Via Clock Skew Scheduling Delay Padding and Glitchless written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes PGR, an architectural technique to reduce dynamic power via a glitch reduction strategy named GlitchLess, or to improve performance via clock skew scheduling (CSS) and delay padding (DP). It is integrated into VPR 5.0, and is invoked after the routing stage. Programmable delay elements (PDEs) are used as a novel architecture modification to insert delay on fiip- flop (FF) clock inputs, enabling all optimization steps to share it, avoiding multiple architecture modifications. This thesis investigates the trade- off between power and performance, and finding an appropriate compromise considering process variation and timing uncertainties. To facilitate realistic power estimates, a popular activity estimator, ACE, is modified with a new model to estimate glitching power, taking into account the analog behavior of glitch pulse width reduction as it travels along FPGA routing tracks. We show that the original glitch estimation method can underestimate glitching power by up to 48%, and overestimate by up to 15%. In terms of performance, an average of 15% speedup can be achieved via CSS alone, or up to 37% for individual circuits. Although delay padding only benefits a few circuits, the average improvement of those circuits is an additional 10% of the original period, or up to 23% for individual circuits. In addition, GlitchLess is performed on both the original VPR and post-CSS solutions. On average, 16% of glitching power can be eliminated, or up to 63% for individual circuits.

Download or read book Timing Optimization Through Clock Skew Scheduling written by Ivan S. Kourtev and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: History of the Book The last three decades have witnessed an explosive development in integrated circuit fabrication technologies. The complexities of cur rent CMOS circuits are reaching beyond the 100 nanometer feature size and multi-hundred million transistors per integrated circuit. To fully exploit this technological potential, circuit designers use sophisticated Computer-Aided Design (CAD) tools. While supporting the talents of innumerable microelectronics engineers, these CAD tools have become the enabling factor responsible for the successful design and implemen tation of thousands of high performance, large scale integrated circuits. This research monograph originated from a body of doctoral disserta tion research completed by the first author at the University of Rochester from 1994 to 1999 while under the supervision of Prof. Eby G. Friedman. This research focuses on issues in the design of the clock distribution net work in large scale, high performance digital synchronous circuits and particularly, on algorithms for non-zero clock skew scheduling. During the development of this research, it has become clear that incorporating timing issues into the successful integrated circuit design process is of fundamental importance, particularly in that advanced theoretical de velopments in this area have been slow to reach the designers' desktops.

The inaugural workshop, Towards Evolvable Hardware, took place in Lausanne in October 1995, followed by the First International Conference on Evolvable Systems: From Biology to Hardware (ICES), held in Tsukuba, Japan in October 1996. The second ICES conference was held in Lausanne in September 1998, with the third and fourth being held in Edinburgh, April 2000 and Tokyo, October 2001 respectively. This has become the leading conference in the ?eld of evolvable systems and the 2003 conference promised to be at least as good as, if not better than, the four that preceeded it. The ?fth international conference was built on the success of its predec- sors, aiming at presenting the latest developments in the ?eld. In addition, it brought together researchers who use biologically inspired concepts to imp- ment real systems in arti?cial intelligence, arti?cial life, robotics, VLSI design and related domains. We would say that this ?fth conference followed on from the previous four in that it consisted of a number of high-quality interesting thought-provoking papers.

Download or read book Verilog Frequently Asked Questions written by Shivakumar S. Chonnad and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Verilog Hardware Description Language was first introduced in 1984. Over the 20 year history of Verilog, every Verilog engineer has developed his own personal “bag of tricks” for coding with Verilog. These tricks enable modeling or verifying designs more easily and more accurately. Developing this bag of tricks is often based on years of trial and error. Through experience, engineers learn that one specific coding style works best in some circumstances, while in another situation, a different coding style is best. As with any high-level language, Verilog often provides engineers several ways to accomplish a specific task. Wouldn’t it be wonderful if an engineer first learning Verilog could start with another engineer’s bag of tricks, without having to go through years of trial and error to decide which style is best for which circumstance? That is where this book becomes an invaluable resource. The book presents dozens of Verilog tricks of the trade on how to best use the Verilog HDL for modeling designs at various level of abstraction, and for writing test benches to verify designs. The book not only shows the correct ways of using Verilog for different situations, it also presents alternate styles, and discusses the pros and cons of these styles.
