Essentials of Electronic Testing for Digital Memory and Mixed Signal VLSI Circuits 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. to Testing VLSI Testing Process and Test Equipment Test Economics and Product Quality Fault Modeling Test Methods Logic and Fault Simulation Testability Measures Combinational Circuit Test Generation Sequential Circuit Test Generation Memory Test DSP Based Analog and Mixed Signal Test Model Based Analog and Mixed Signal Test Delay Test IDDQ Test Design for Testability Digital DFT and Scan Design Built In Self Test Boundary Scan Standard Analog Test Bus Standard System Test and Core Based Design The Future of Testing.
