In this paper a new structural method for linear output space compaction for synchronous sequential circuits is presented. Based on simple estimates for the probabilities of the existence of sensitized paths from the signal lines to the circuit outputs, optimal output partitions are determined without fault simulation. The method is developed for concurrent checking, but as the experimental results show, it is also effectively applicable in pseudo-random test mode.
