Claim Text:
1. A computer program product for implementing design-based weighting for logic built-in self-test (LBIST), the computer program product comprising: a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising: analyzing, by the processing circuit, a plurality of integrated circuit design organizational units to determine preferred weightings of the integrated circuit design organizational units that provide a highest level of failure coverage when applied to a random pattern generator; based on determining the preferred weightings, creating, by the processing circuit, an integrated circuit layout comprising a plurality of weighted test paths to respectively apply the preferred weightings to the integrated circuit design organizational units, wherein the integrated circuit design or organizational units are assignable to perform LBIST using the preferred weightings as design-based weighting within a device under test; and incorporating the integrated circuit layout in the device under test.
