This paper presents the impact of multiple-detect test patterns on outgoing product quality. It introduces an ATPG tool that generates multiple-detect test patterns while maximizing the coverage of node-tonode bridging defects. Volume data obtained by testing a production ASIC with these new multipledetect patterns shows increased defect screening capability and very good agreement with the bridging coverage estimated by the ATPG tool.
