Book Description
The modern electronic testing has a forty year history. Test professionals hold some fairly large conferences and numerous workshops, have a journal, and there are over one hundred books on testing. Still, a full course on testing is offered only at a few universities, mostly by professors who have a research interest in this area. Apparently, most professors would not have taken a course on electronic testing when they were students. Other than the computer engineering curriculum being too crowded, the major reason cited for the absence of a course on electronic testing is the lack of a suitable textbook. For VLSI the foundation was provided by semiconductor device techn- ogy, circuit design, and electronic testing. In a computer engineering curriculum, therefore, it is necessary that foundations should be taught before applications. The field of VLSI has expanded to systems-on-a-chip, which include digital, memory, and mixed-signalsubsystems. To our knowledge this is the first textbook to cover all three types of electronic circuits. We have written this textbook for an undergraduate “foundations” course on electronic testing. Obviously, it is too voluminous for a one-semester course and a teacher will have to select from the topics. We did not restrict such freedom because the selection may depend upon the individual expertise and interests. Besides, there is merit in having a larger book that will retain its usefulness for the owner even after the completion of the course. With equal tenacity, we address the needs of three other groups of readers.

Book Description
Very Large-Scale Integration (VLSI) creates an integrated circuit (IC) by combining thousands of transistors into a single chip. While designing a circuit, reduction of power consumption is a great challenge. VLSI designs reduce the size of circuits which eventually reduces the power consumption of the devices. However, it increases the complexity of the digital system. Therefore, computer-aided design tools are introduced into hardware design processes. Unlike the general-purpose computer, an embedded system is engineered to manage a wide range of processing tasks. Single or multiple processing cores manage embedded systems in the form of microcontrollers, digital signal processors, field-programmable gate arrays, and application-specific integrated circuits. Security threats have become a significant issue since most embedded systems lack security even more than personal computers. Many embedded systems hacking tools are readily available on the internet. Hacking in the PDAs and modems is a pervasive example of embedded systems hacking. This book explores the designs of VLSI circuits and embedded systems. These two vast topics are divided into four parts. In the book's first part, the Decision Diagrams (DD) have been covered. DDs have extensively used Computer-Aided Design (CAD) software to synthesize circuits and formal verification. The book's second part mainly covers the design architectures of Multiple-Valued Logic (MVL) Circuits. MVL circuits offer several potential opportunities to improve present VLSI circuit designs. The book's third part deals with Programmable Logic Devices (PLD). PLDs can be programmed to incorporate a complex logic function within a single IC for VLSI circuits and Embedded Systems. The fourth part of the book concentrates on the design architectures of Complex Digital Circuits of Embedded Systems. As a whole, from this book, core researchers, academicians, and students will get the complete picture of VLSI Circuits and Embedded Systems and their applications.

Book Description
This book facilitates the VLSI-interested individuals with not only in-depth knowledge, but also the broad aspects of it by explaining its applications in different fields, including image processing and biomedical. The deep understanding of basic concepts gives you the power to develop a new application aspect, which is very well taken care of in this book by using simple language in explaining the concepts. In the VLSI world, the importance of hardware description languages cannot be ignored, as the designing of such dense and complex circuits is not possible without them. Both Verilog and VHDL languages are used here for designing. The current needs of high-performance integrated circuits (ICs) including low power devices and new emerging materials, which can play a very important role in achieving new functionalities, are the most interesting part of the book. The testing of VLSI circuits becomes more crucial than the designing of the circuits in this nanometer technology era. The role of fault simulation algorithms is very well explained, and its implementation using Verilog is the key aspect of this book. This book is well organized into 20 chapters. Chapter 1 emphasizes on uses of FPGA on various image processing and biomedical applications. Then, the descriptions enlighten the basic understanding of digital design from the perspective of HDL in Chapters 2–5. The performance enhancement with alternate material or geometry for silicon-based FET designs is focused in Chapters 6 and 7. Chapters 8 and 9 describe the study of bimolecular interactions with biosensing FETs. Chapters 10–13 deal with advanced FET structures available in various shapes, materials such as nanowire, HFET, and their comparison in terms of device performance metrics calculation. Chapters 14–18 describe different application-specific VLSI design techniques and challenges for analog and digital circuit designs. Chapter 19 explains the VLSI testability issues with the description of simulation and its categorization into logic and fault simulation for test pattern generation using Verilog HDL. Chapter 20 deals with a secured VLSI design with hardware obfuscation by hiding the IC’s structure and function, which makes it much more difficult to reverse engineer.

Book Description
Test power is an important issue in deep submicron semiconductor testing. Too much power supply noise and too much power dissipation can result in excessive temperature rise, both leading to overkill during delay test. Scan-based test has been widely adopted as one of the most commonly used VLSI testing method. The test power during scan testing comprises shift power and capture power. The power consumed in the shift cycle dominates the total power dissipation. It is crucial for IC manufacturing companies to achieve near constant power consumption for a given timing window in order to keep the chip under test (CUT) at a near constant temperature, to make it easy to characterize the circuit behavior and prevent delay test over kill. To achieve constant test power, first, we built a fast and accurate power model, which can estimate the shift power without logic simulation of the circuit. We also proposed an efficient and low power X-bit Filling process, which could potentially reduce both the shift power and capture power. Then, we introduced an efficient test pattern reordering algorithm, which achieves near constant power between groups of patterns. The number of patterns in a group is determined by the thermal constant of the chip. Experimental results show that our proposed power model has very good correlation. Our proposed X-Fill process achieved both minimum shift power and capture power. The algorithm supports multiple scan chains and can achieve constant power within different regions of the chip. The greedy test pattern reordering algorithm can reduce the power variation from 29-126 percent to 8-10 percent or even lower if we reduce the power variance threshold. Excessive noise can significantly affect the timing performance of Deep Sub-Micron (DSM) designs and cause non-trivial additional delay. In delay test generation, test compaction and test fill techniques can produce excessive power supply noise. This can result in delay test overkill. Prior approaches to power supply noise aware delay test compaction are too costly due to many logic simulations, and are limited to static compaction. We proposed a realistic low cost delay test compaction flow that guardbands the delay using a sequence of estimation metrics to keep the circuit under test supply noise more like functional mode. This flow has been implemented in both static compaction and dynamic compaction. We analyzed the relationship between delay and voltage drop, and the relationship between effective weighted switching activity (WSA) and voltage drop. Based on these correlations, we introduce the low cost delay test pattern compaction framework considering power supply noise. Experimental results on ISCAS89 circuits show that our low cost framework is up to ten times faster than the prior high cost framework. Simulation results also verify that the low cost model can correctly guardband every path's extra noise-induced delay. We discussed the rules to set different constraints in the levelized framework. The veto process used in the compaction can be also applied to other constraints, such as power and temperature.

Book Description
In the early days of digital design, we were concerned with the logical correctness of circuits. We knew that if we slowed down the clock signal sufficiently, the circuit would function correctly. With improvements in the semiconductor process technology, our expectations on speed have soared. A frequently asked question in the last decade has been how fast can the clock run. This puts significant demands on timing analysis and delay testing. Fueled by the above events, a tremendous growth has occurred in the research on delay testing. Recent work includes fault models, algorithms for test generation and fault simulation, and methods for design and synthesis for testability. The authors of this book, Angela Krstic and Tim Cheng, have personally contributed to this research. Now they do an even greater service to the profession by collecting the work of a large number of researchers. In addition to expounding such a great deal of information, they have delivered it with utmost clarity. To further the reader's understanding many key concepts are illustrated by simple examples. The basic ideas of delay testing have reached a level of maturity that makes them suitable for practice. In that sense, this book is the best x DELAY FAULT TESTING FOR VLSI CIRCUITS available guide for an engineer designing or testing VLSI systems. Tech niques for path delay testing and for use of slower test equipment to test high-speed circuits are of particular interest.
