This paper presents a new approach for designing testsequences to be generated on-chip. The proposedtechnique is based on machine learning, and provides a wayto generate efficient patterns to be used during BIST testpattern generation. The main idea is that test patternsdetecting random pattern resistant faults are not embeddedin a pseudo-random sequence as in existing techniques, butrather are used to produce relevant features allowing togenerate directed random test patterns that detect randompattern resistant faults as well as easy-to-test faults. A BISTimplementation that uses a classical LFSR plus a smallamount of mapping logic is also proposed in this paper.Results are shown for benchmark circuits which indicatethat our technique can reduce the weighted orpseudo-random test length required for a particular faultcoverage. Other results are given to show the possible tradeoff between hardware overhead and test sequence length.An encouraging point is that results presented in this paper,although they are comparable with those of existingmixed-mode techniques, have been obtained with amachine learning tool not specifically developed for BISTgeneration and therefore may significantly be improved.
