Fault grading is a procedure that rates testability by relating the number of fabrication defects that can in fact be detected with a test vector set under consideration to the total number of conceivable faults. It is used for refining both the test circuitry and the test patterns iteratively, until a satisfactory fault coverage is obtained.
