ABSTRACT


The technological development is enabling the production of increasingly complex electronic systems. All such systems must be verified and tested to guarantee their correct behavior. As the complexity grows, testing has become one of the most significant factors that contribute to the total development cost. In recent years, we have also witnessed the inadequacy of the established testing methods, most of which are based on low-level representations of the hardware circuits. Therefore, more work has to be done at abstraction levels higher than the classical gate and register- transfer levels. At the same time, the automatic test equipment based solutions have failed to deliver the required test quality. As a result, alternative testing methods have been studied, which has led to the development of built-in self-test (BIST) techniques.

In this thesis, we present a novel hybrid BIST technique that addresses several areas where classical BIST methods have shortcomings. The technique makes use of both pseudorandom and deterministic testing methods, and is devised in particular for testing modern systems-on-chip. One of the main contributions of this thesis is a set of optimization methods to reduce the hybrid test cost while not sacrificing test qund efficiency of the proposed methodologies and techniques.
