Defect-Oriented Testing for Nano-Metric CMOS VLSI Circuits


Book Description

The 2nd edition of defect oriented testing has been extensively updated. New chapters on Functional, Parametric Defect Models and Inductive fault Analysis and Yield Engineering have been added to provide a link between defect sources and yield. The chapter on RAM testing has been updated with focus on parametric and SRAM stability testing. Similarly, newer material has been incorporated in digital fault modeling and analog testing chapters. The strength of Defect Oriented Testing for nano-Metric CMOS VLSIs lies in its industrial relevance.




Defect Oriented Testing for CMOS Analog and Digital Circuits


Book Description

Defect oriented testing is expected to play a significant role in coming generations of technology. Smaller feature sizes and larger die sizes will make ICs more sensitive to defects that can not be modeled by traditional fault modeling approaches. Furthermore, with increased level of integration, an IC may contain diverse building blocks. Such blocks include, digital logic, PLAs, volatile and non-volatile memories, and analog interfaces. For such diverse building blocks, traditional fault modeling and test approaches will become increasingly inadequate. Defect oriented testing methods have come a long way from a mere interesting academic exercise to a hard industrial reality. Many factors have contributed to its industrial acceptance. Traditional approaches of testing modern integrated circuits (ICs) have been found to be inadequate in terms of quality and economics of test. In a globally competitive semiconductor market place, overall product quality and economics have become very important objectives. In addition, electronic systems are becoming increasingly complex and demand components of highest possible quality. Testing, in general and, defect oriented testing, in particular, help in realizing these objectives. Defect Oriented Testing for CMOS Analog and Digital Circuits is the first book to provide a complete overview of the subject. It is essential reading for all design and test professionals as well as researchers and students working in the field. `A strength of this book is its breadth. Types of designs considered include analog and digital circuits, programmable logic arrays, and memories. Having a fault model does not automatically provide a test. Sometimes, design for testability hardware is necessary. Many design for testability ideas, supported by experimental evidence, are included.' ... from the Foreword by Vishwani D. Agrawal

Introduction to IDDQ Testing


Book Description

Testing techniques for VLSI circuits are undergoing many exciting changes. The predominant method for testing digital circuits consists of applying a set of input stimuli to the IC and monitoring the logic levels at primary outputs. If, for one or more inputs, there is a discrepancy between the observed output and the expected output then the IC is declared to be defective. A new approach to testing digital circuits, which has come to be known as IDDQ testing, has been actively researched for the last fifteen years. In IDDQ testing, the steady state supply current, rather than the logic levels at the primary outputs, is monitored. Years of research suggests that IDDQ testing can significantly improve the quality and reliability of fabricated circuits. This has prompted many semiconductor manufacturers to adopt this testing technique, among them Philips Semiconductors, Ford Microelectronics, Intel, Texas Instruments, LSI Logic, Hewlett-Packard, SUN microsystems, Alcatel, and SGS Thomson. This increase in the use of IDDQ testing should be of interest to three groups of individuals associated with the IC business: Product Managers and Test Engineers, CAD Tool Vendors and Circuit Designers. Introduction to IDDQ Testing is designed to educate this community. The authors have summarized in one volume the main findings of more than fifteen years of research in this area.







Testing for Small-Delay Defects in Nanoscale CMOS Integrated Circuits


Book Description

Advances in design methods and process technologies have resulted in a continuous increase in the complexity of integrated circuits (ICs). However, the increased complexity and nanometer-size features of modern ICs make them susceptible to manufacturing defects, as well as performance and quality issues. Testing for Small-Delay Defects in Nanoscale CMOS Integrated Circuits covers common problems in areas such as process variations, power supply noise, crosstalk, resistive opens/bridges, and design-for-manufacturing (DfM)-related rule violations. The book also addresses testing for small-delay defects (SDDs), which can cause immediate timing failures on both critical and non-critical paths in the circuit. Overviews semiconductor industry test challenges and the need for SDD testing, including basic concepts and introductory material Describes algorithmic solutions incorporated in commercial tools from Mentor Graphics Reviews SDD testing based on "alternative methods" that explores new metrics, top-off ATPG, and circuit topology-based solutions Highlights the advantages and disadvantages of a diverse set of metrics, and identifies scope for improvement Written from the triple viewpoint of university researchers, EDA tool developers, and chip designers and tool users, this book is the first of its kind to address all aspects of SDD testing from such a diverse perspective. The book is designed as a one-stop reference for current industrial practices, research challenges in the domain of SDD testing, and recent developments in SDD solutions.
