Simulation and SAT Based ATPG for Compressed Test Generation

This paper presents a novel ATPG algorithm directly producing compressed test patterns. It benefits both from the features of satisfiability-based techniques and symbolic simulation. The ATPG is targeted to architectures comprised of interconnected embedded cores, particularly to the RESPIN architecture. We show experimentally that the proposed ATPG significantly outperforms the state-of-the-art approaches in terms of the test compression ratio.
