Built-In Self-Test (BIST) is a method of designing and creating an electronic chip or an electronic system that can self test for correct functionality and ensure no manufacturing defects. The reason for analog BIST is the testing of analog parts of analog and mixed-signal ICs is a costly process that traditionally requires the use of expensive high-end automatic test equipment. Due to the nature of the testing and length of the testing process, an efficient analog BIST scheme is in high demand for the ever increasing complexity of analog and mixed-signal circuits. This thesis presents a BIST scheme for generation and response waveform extraction that allows the detection of a faulty circuit design. Along with the detection, an approach to test high speed analog and mixed-signal circuits with test signals upwards of 1GHz is presented. A practical application is to test analog or mixed-signal IC that has a wide bandwidth ADC in its front-end. The BIST scheme includes a method to store the test signal and generate it for the circuit to be tested along with a way to extract the response test signal from multiple test points and allow fault detection. Along with this research, a stepping stone is implemented for analog modeling using MATLAB for accuracy and speed of circuit simulations. The problems associated with the BIST scheme and analog modeling is discussed, along with recommendations.

Analog Signal Generation for Built-In-Self-Test (BIST) of Mixed-Signal Integrated Circuits is a concise introduction to a powerful new signal generation technique. The book begins with a brief introduction to the testing problem and a review of conventional signal generation techniques. The book then describes an oversampling-based oscillator capable of generating high-precision analog tones using a combination of digital logic and D/A conversion. These concepts are then extended to multi-tone testing schemes without introducing a severe hardware penalty. The concepts are extended further to encompass piece-wise linear waveforms such as square, triangular and sawtooth waves. Experimental results are presented to verify the ideas in each chapter and finally, conclusions are drawn. For those readers unfamiliar with delta-sigma modulation techniques, a brief introduction to this subject is also provided in an appendix. The book is ideal for test engineers, researchers and circuits designers with an interest in IC testing methods.

Analog Test Signal Generation Using Periodic SigmaDelta-Encoded Data Streams presents a new method to generate high quality analog signals with low hardware complexity. The theory of periodic SigmaDelta-encoded bitstreams is presented along with a set of empirical tables to help select the appropriate parameters of a bitstream. An optimization procedure is also outlined to help select a bit sequence with the desired attributes. A large variety of signals can be generated using this approach. Silicon implementation issues are discussed with a specific emphasis on area overhead and ease of design. One FPGA circuit and three different silicon implementations are presented along with experimental results. It is shown that simple designs are capable of generating very high precision signals-on-chip. The technique is further extended to multi-bit signal generation where it is shown how to increase the performance of arbitrary waveform, generators commonly found in past and present-day mixed-signal testers. No hardware modifications are required, only the numbers in memory are changed. Three different calibration techniques to reduce the effects of the AWG's non-linearities are also introduced, together with supporting experimental evidence. The main focus of this text is to describe an area-efficient technique for analog signal generation using SigmaDelta-encoded data stream. The main characteristics of the technique are: High quality signals (SFDR of 110 dB observed); Large variety of signals generated; Bitstreams easily obtained with a fast optimization program; Good frequency resolution, compatible with coherent sampling; Simple and fast hardware implementation; Mostly digital, except an easily testable 1-bit DAC and possibly a reconstruction filter; Memory already available on-chip can be reused, reducing area overhead; Designs can be incorporated into existing CAD tools; High frequency generation.

A Built-In Self-Test architecture was developed for testing analog circuits in mixed-signal systems. The Built-In Self-Test circuitry primarily resides in the digital portion of the mixed-signal system in order to minimize performance impact on the analog circuitry. The test pattern generation portion of the Built-In Self-Test circuitry produces a number of different test waveforms found to be effective in detecting faults in the analog circuitry. The output response analysis function consists of a double-precision accumulator that facilitates determination of the faulty/fault-free status of an analog circuit with acceptable component parameter variations. Ten benchmark circuits were established for the evaluation of analog testing approaches along with acceptable component parameter variations and a standard set of faults and fault models for each benchmark circuit. Finally, an equation was developed for the calculation of analog fault coverage that takes into consideration the probability of potential detection of faults due to component parameter variation. Evaluation of the Built-In Self-Test architecture via analog fault simulation using the benchmark circuits and the fault coverage equation indicates that the approach is effective in detecting catastrophe and parametric faults in a wide variety of analog circuits.
