Automatic test pattern generation
ATPG is an electronic design automation method or technology used to find an input sequence that, when applied to a digital circuit, enables automatic test equipment to distinguish between the correct circuit behavior and the faulty circuit behavior caused by defects. The generated patterns are used to test semiconductor devices after manufacture, or to assist with determining the cause of failure. The effectiveness of ATPG is measured by the number of modeled defects, or fault models, detectable and by the number of generated patterns. These metrics generally indicate test quality and test application time. ATPG efficiency is another important consideration that is influenced by the fault model under consideration, the type of circuit under test, the level of abstraction used to represent the circuit under test, and the required test quality.
