Tessent LogicBIST with Observation Scan Technology

Meeting the ISO 26262 requirements for high quality and long-term reliability mans implementing on-chip safety mechanisms with high defect coverage of IC logic. This paper describes Observation Scan Technology, the logic built-in-self-test (BIST) technology that improves test quality and reduces in-system test time. Empirical results demonstrate 90% test coverage with up to 10X fewer LBIST patterns when compared with previous industry-leading LBIST solutions.
