Demonstrates techniques which will allow rewiring rates of over 95%, enabling adoption of deep sub-micron chips for industrial applications Logic synthesis is an essential part of the modern digital IC design process in semi-conductor industry. This book discusses a logic synthesis technique called “rewiring” and its latest technical advancement in term of rewirability. Rewiring technique has surfaced in academic research since 1993 and there is currently no book available on the market which systematically and comprehensively discusses this rewiring technology. The authors cover logic transformation techniques with concentration on rewiring. For many decades, the effect of wiring on logic structures has been ignored due to an ideal view of wires and their negligible role in the circuit performance. However in today’s semiconductor technology wiring is the major player in circuit performance degeneration and logic synthesis engines can be improved to deal with this through wire-based transformations. This book introduces the automatic test pattern generation (ATPG)-based rewiring techniques, which are recently active in the realm of logic synthesis/verification of VLSI/SOC designs. Unique comprehensive coverage of semiconductor rewiring techniques written by leading researchers in the field Provides complete coverage of rewiring from an introductory to intermediate level Rewiring is explained as a flexible technique for Boolean logic synthesis, introducing the concept of Boolean circuit transformation and testing, with examples Readers can directly apply the described techniques to real-world VLSI design issues Focuses on the automatic test pattern generation (ATPG) based rewiring methods although some non-ATPG based rewiring methods such as graph based alternative wiring (GBAW), and “set of pairs of functions to be distinguished” (SPFD) based rewiring are also discussed A valuable resource for researchers and postgraduate students in VLSI and SoC design, as well as digital design engineers, EDA software developers, and design automation experts that specialize in the synthesis and optimization of logical circuits.
A unique, practical approach to the design of high-speed digital circuit boards The demand for ever-faster digital circuit designs is beginning to render the circuit theory used by engineers ineffective. Digital Circuit Boards presents an alternative to the circuit theory approach, emphasizing energy flow rather than just signal interconnection to explain logic circuit behavior. The book shows how treating design in terms of transmission lines will ensure that the logic will function, addressing both storage and movement of electrical energy on these lines. It covers transmission lines in all forms to illustrate how trace geometry defines where the signals can travel, then goes on to examine transmission lines as energy sources, the true nature of decoupling, types of resonances, ground bounce, cross talk, and more. Providing designers with the tools they need to lay out digital circuit boards for fast logic and to get designs working the first time around, Digital Circuit Boards: Reviews in simple terms the basic physics necessary to understand fast logic design Debunks the idea that electrical conductors carry power and signals, showing that signal travels in the spaces, not the traces, of circuit boards Explains logic circuit behavior through real-time analysis involving the fields and waves that carry signal and energy Provides new information on how ground/power planes work Outlines a software program for solving energy flow in complex networks
The Powerful Sandwich will give you stripped-down, unbiased, practical life lessons that many, if not all of us, have experienced or can certainly relate to. It is a message of good news in the midst of things that we all may consider to be bad. God would like us to look at these bad things through His eyes. Much of the sting is alleviated. More of the hope and possibilities of something good replaces the old feelings of failure, fear, and loneliness. It is a very quick read and yet a very powerful one. Just a tweak in the way we process our thoughts can turn the entire direction of our lives around. Good reading to you. May you receive a nugget or two that resonates in your heart and touches your soul.
