Abstract

This paper aims at broadening the scope of hierarchicalATPG to the behavioral-level. The main problem is identified, namelythe mismatch of timing models between the behavioral- andgate-levels. As a main contribution of this paper, a theoreticalanalysis of this problem led to the definition of a novel concept,that of dominated patterns, that captures the needed linkbetween the levels. Some metrics are defined, taken from the softwarerealm, that allow generation of test patterns at thebehavioral-level. To validate the concept correctness, different ATPGsystems are presented, and experimental results show an improvementin the test quality, thanks to the exploitation of behavioral-levelinformation.
