Abstract
A method of locating faulty logic on a semiconductor chip is disclosed. The method may include determining failure rates for the semiconductor chip, which contain one or more logic elements. The method also may include determining a masking pattern using failure rates. The masking pattern may mask less than all of the logic elements using a determination method. The method may also include applying a test vector to a selected logic element, wherein the result from a test vector is compared to a reference.
