Timing

Timing belts offer a broad range of innovative drivetrain solutions; they allow low-backlash operation in robot systems, they are widely used in automated processes and industrial handling involving highly dynamic start-up loads, they are low-maintenance solutions for continuous operation applications, and they can guarantee exact positioning at high operating speeds. Based on his years of professional experience, the author has developed concise guidelines for the dimensioning of timing belt drives and presents proven examples from the fields of power transmission, transport and linear transfer technology. He offers definitive support for dealing with and compensating for adverse operating conditions and belt damage, as well as advice on drive optimization and guidelines for the design of drivetrain details and supporting systems. All market-standard timing belts are listed as brand neutral. Readers will discover an extensive bibliography with information on the various manufacturers and their websites. This practical handbook addresses both the needs of application engineers working in design, development and machine-building, and is well-suited as a textbook for students at universities and vocational schools alike.

Large system complexities and operation under tight timing constraints in rapidly shrinking technologies have made it extremely important to ensure correct temporal behavior of modern-day digital circuits, both before and after fabrication. Research in (pre-fabrication) timing verification and (post-fabrication) delay fault testing has evolved along largely disjoint lines in spite of the fact that they share many basic concepts. A Unified Approach for Timing Verification and Delay Fault Testing applies concepts developed in the context of delay fault testing to path sensitization, which allows an accurate timing analysis mechanism to be developed. This path sensitization strategy is further applied for efficient delay fault diagnosis and delay fault coverage estimation. A new path sensitization strategy called Signal Stabilization Time Analysis (SSTA) has been developed based on the fact that primitive PDFs determine the stabilization time of the circuit outputs. This analysis has been used to develop a feasible method of identifying the primitive PDFs in a general multi-level logic circuit. An approach to determine the maximum circuit delay using this primitive PDF identification mechanism is also presented. The Primitive PDF Identification-based Timing Analysis (PITA) approach is proved to determine the maximum floating mode circuit delay exactly under any component delay model, and provides several advantages over previously floating mode timing analyzers. A framework for the diagnosis of circuit failures caused by distributed path delay faults is also presented. A metric to quantify the diagnosability of a path delay fault for a test is also proposed. Finally, the book presents a very realistic metric for delay fault coverage which accounts for delay fault size distributions and is applicable to any delay fault model. A Unified Approach for Timing Verification and Delay Fault Testing will be of interest to university and industry researchers in timing analysis and delay fault testing as well as EDA tool development engineers and design verification engineers dealing with timing issues in ULSI circuits. The book should also be of interest to digital designers and others interested in knowing the state of the art in timing verification and delay fault testing.

In this companion volume to A Space for Grace, Johan Cilliers delves into some of the most profound theological underpinnings of preaching. Drawing on his extraordinary depth and breadth of scholarship, Cilliers examines the aesthetic, qualitative, and relational dimensions of sermonic time. Faithful preaching, he argues, is an art of speaking the now of grace, which is inextricably linked to past and future, but is simultaneously a dynamic event filled with the revelatory presence of God. Along with helpful reflections on pieces of visual art, Cilliers provides numerous sample sermons, as well as several detailed sermon analyses.

This unique book outlines a brand-new approach of how to do timing signoff of complex microchips with the minimum number of corners. It is the first book in my planned series of books on global and local on-chip variations (OCV) and statistical, Monte-Carlo-based methods of timing signoff. I have spent more than 7 years on developing those new methods and now will share my results with the electronic design community. Each book will have a short version as a E-book that will be followed by a paperback/cover full version book with all important details. The books are mainly targeting microchip designers and software engineers in Electronic Design Automation (EDA) companies as well as companies that design and/or manufacture microchips. The number of timing signoff corners exponentially grows and makes microchip design very complex, time consuming, or even impossible to close timing. Additionally, there is a toll on microchip performance due to conservatism, which increases with the corner number. All delay, dimension, and other absolute values are scaled (or normalized) and do not represent real values/parameters of any particular technology node or design. Initially, I focus on factors impacting the corner number and how to find the minimum number of traditional Power, Voltage, Temperature (PVT), and Resistance, Capacitance (RC) corners. Then, I outline a break-through method with the absolute minimum of the corner number where instead of PVT/RC corners I introduce 4 min/max timing delay corners (so-called slack corners). Then, I discuss a new approach on how to design for the maximum profit by setting a proper target for the timing yield Y during timing signoff. Finally, I discuss possible enhancements in signoff paradigms, methods, and statistical STA tools. The importance of these pseudo- and fully statistical Monte Carlo-based post-STA methods is to study OCV variations in detail and justify all OCV derates for STA tools no matter whether the PVT/RC corners signoff is or the 4-slack corners is used.

This report summarizes the results of the National Signal Timing Organization Project initiated by the Federal Highway Administration as a fuel conservation effort. The objectives of this project are: 1) to establish credible data on the effectiveness of signal timing optimization; 2) to make signal timing optimization projects easier to do; and 3) to define the resources (cost, level of staff, computer, etc.) required to undertake a signal timing optimization project, so that traffic engineers and administrators can more effectively budget for this activity. The project consisted of the development of the TRANSYT-7F signal timing optimization program User's Manual, and training course, and application of the program in 11 cities nationwide to evaluate the effectiveness of the poptimized signal timing plans and to collect data on the needed resources.
