Available in PDF, EPUB and Kindle. Book excerpt: The continual explosion of computer development has led to inadequate coverage of proper & useful on-line testing techniques. This text fills the gap in the literature by presenting the latest techniques available for digital devices used in the most popular computers. Initial chapters explore the classic problems of on-line testing, pointing out the limited applications of conventional approaches to the problem of diagnosing digital devices using LSI & VLSI chips. Chapters 4-7 cover compact testing methods used to diagnose complex digital circuits. Chapters 8 & 9 analyze the techniques of compressing output responses of a digital circuit, while chapter 10 surveys promising recent signature generation techniques for binary sequences. The final chapter covers multi-output digital circuits.

Available in PDF, EPUB and Kindle. Book excerpt: The goals of fault diagnosis are to ascertain whether faults are present in (fault detection) and to identify them (fault location). Fault location is commonly performed with the aid of a fault dictionary. Fault dictionaries are constructed via fault simulation under the single fault assumption. The single fault-model often assumes a circuit is tested often enough such that no more than one physical defect is likely to occur between two consecutive test applications. This strategy is not valid when one physical defect manifests itself as multiple faults. It is observed that the presence of redundant faults also invalidates the frequent testing strategy, since a redundant fault may mask the existence of a detectable fault. In all these situations, a multiple fault model is required. However, in almost all practical cases a fault dictionary for multiple faults is infeasible to generate due to an exponential number of equivalence classes. In this dissertation, we first present a VHDL-based CAD tool that integrates design error injection, simulation, and diagnosis for digital circuits. The tool uses an FPGA-based board to inject error models in the design and compute the error free and erroneous signatures of internal lines. The signatures are later used for detection and diagnosis of errors for the circuit under test (CUT). Several experiments were conducted to demonstrate the capabilities of the tool. The obtained results demonstrate that the tool could detect and locate the source faulty node(s) within the CUT. Then, a new approach for a developed fault diagnosis method. Our approach is based on an enhanced deduction algorithm, which processes the actual response (effect) of CUT, to determine fault situations (causes). The main tool of our approach processes the response to deduce the internal signal values. A multiple stuck at fault model is implicitly employed and no-fault enumeration is required. The enhanced deduction algorithm is applicable to complicated combinational circuits. The internal values obtained are used to determine fault situations in CUT compatible with the applied test T and the response. Our analysis can identify fault locations and values (s-a-0 or s-a-1). Our main result is that any stuck fault can be diagnosed. Preliminary results demonstrate that our technique always achieves great accuracy for detecting and locating the faults, saving a large amount of time, especially for more complicated combinational circuits. The problems solved by our procedure are using deterministic test vectors. We next present a new approach for a developed fault diagnosis method. Our approach is based on an enhanced deduction algorithm and a backtracking strategy which can be regarded as a recursive process of value justification in which we first justify (explain) the values obtained at the primary outputs (POs). To justify a (0) value on the output of a- NAND gate (assuming it is normal), we need all the gate inputs to be (1). To justify a (1) value we need at least one input to have value (0). All the known values of internal normal lines must be justified by values of their predecessors. When both 0 and 1 values have been deduced for a gate output and it is critical, it is identified as normal and all its currently known values are analyzed. In some cases, we need to decide to select one of the possible ways to justify a (1) value on the output of a- NAND gate. If a decision leads to an inconsistency (self-contradictory state) with the forward propagated value, the algorithm will backtrack to the last decision point and try an alternative decision. After a decision is made, all the implications resulting from that decision are performed. If no inconsistency is detected, a new decision point is necessary. Otherwise, a solution has been obtained. A solution is a set of values which could have occurred in the CUT, that is, a possible set of actual values. The main tool of our approach processes the response to deduce the internal signal values in all possible solutions.

This book was released on 2012-12-06 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: IS THE TOPIC ANALOG TESTING AND DIAGNOSIS TIMELY? Yes, indeed it is. Testing and Diagnosis is an important topic and fulfills a vital need for the electronic industry. The testing and diagnosis of digital electronic circuits has been successfuIly developed to the point that it can be automated. Unfortu nately, its development for analog electronic circuits is still in its Stone Age. The engineer's intuition is still the most powerful tool used in the industry! There are two reasons for this. One is that there has been no pressing need from the industry. Analog circuits are usuaIly small in size. Sometimes, the engineer's experience and intuition are sufficient to fulfill the need. The other reason is that there are no breakthrough results from academic re search to provide the industry with critical ideas to develop tools. This is not because of a lack of effort. Both academic and industrial research groups have made major efforts to look into this problem. Unfortunately, the prob lem for analog circuits is fundamentally different from and much more diffi cult than its counterpart for digital circuits. These efforts have led to some important findings, but are still not at the point of being practicaIly useful. However, these situations are now changing. The current trend for the design of VLSI chips is to use analog/digital hybrid circuits, instead of digital circuits from the past. Therefore, even Ix x Preface though the analog circuit may be small, the total circuit under testing is large.
