Estimating aliasing in CA and LFSR based signature registers
D. Michael Miller, S. Zhang, W. Pries, Robert D. McLeod · 2002
Aliasing estimations for cellular automata (CA) and linear feedback shift registers (LFSR) data compactors are presented. As data compaction is a heavily relied on technique for built-in self-test (BIST) the results should be of practical, as well as theoretical interest. Aliasing estimation techniques for multiple-input data compactors are considered. In particular, exact and approximate computation techniques are developed and discussed for CA and LFSR registers. Aliasing estimates for CA and LFSR structures are provided for the ISCAS-85 benchmark circuits for single stuck-at and single delay faults.>
