| Abstract(in English) | It is important to find an efficient design-for-testability methodology that satisfies both security and testability though there exists an inherent contradiction between security and testability for digital circuits. The authors reported a secure and testable scan design approach by using extended shift registers that are functionally equivalent but not structurally equivalent to shift registers [11], and clarified each cardinality of several classes of shift register equivalents (SR-equivalents) as well as the whole class of SR-equivalents [12,13]. A new concept of differential behavior equivalent relation for extended shift registers is introduced in this paper. The structures of equivalent classes for several types of extended scan circuits are analyzed and their numbers of equivalent classes and their cardinalities are derived. |
