What is Fault coverage?
The fraction of modeled faults that a set of test patterns can detect. The higher it is, the less likely defective chips are to escape.
Field: Testing and inspection
Fault coverage in the explanations
Fault coverage is the fraction of all modeled faults that the test patterns can detect.
Which is the correct definition of fault coverage for test …Though simple, it represents many physical defects, so it is widely used for automatic test pattern generation and evaluating fault coverage.
Which correctly describes the stuck-at fault model used in …Combined with scan design, it efficiently creates test patterns with high fault coverage even for large circuits.
What is it called to automatically generate test patterns t…
