Abstract

Coverage directed test generation (CDG) is a technique for providing feedback from the coverage domain back to a generator that produces new stimuli to the tested design. In this paper, we describe two algorithms that act in a CDG framework. The first algorithm controls the coverage events distribution using a "water-filling" approach. The second algorithm improves the efficiency of the covering process using clustering techniques.
