Generation of Vector Patterns Through Reseeding of Multipe-Polynominal Linear Feedback Shift Registers

In this paper we perform a comparative analysis of the encoding efficiency of BIST schemes based on reseeding of single polynomial LFSR's as well as LFSR's with fully programmable polynomials. Full programmability gives much better encoding efficiency. For a testcube with s carebits we need only s+4 bits in contrast to s+19 bits for reseeding of single… CONTINUE READING
