Diagnosis of Logic Circuits Using Compressed Deterministic Data and On-Chip Response Comparison

While manufacturing test helps to isolate faulty devices from the good ones, diagnosis is enabling a faster transition from the yield learning to the volume production phase of a new process technology. Given the escalating design complexity, new methods such as embedded deterministic test have been proposed in recent years to deal with the cost of manufacturing test. This paper discusses diagnosis of logic blocks by leveraging the existing …
