V. N. Zakharov ,   L. A. Zakrevskiy Soviet Journal of Computer and Systems Sciences , vol.30 №3 , 01.1992 , language: английский  Аннотация The problem of constructing easy-to-test discrete circuits is examined. A methodology for synthesizing combination circuits and circuits with memory which are accessible for control with a minimal number of input test vectors is described. Issues of modifying a single element as well as the entire circuit with the goal of making them suitable for control are studied.  Ключевые слова Easy-to-test digital circuits, Automata theory, Logical design
