We propose a procedure for designing an LFSRbased circuit for masking of unknown output values that appear in the output response of a circuit tested using LBIST. The procedure is based on reseeding of the LFSR to mask unknown output values while allowing fault effects to propagate. To determine the seeds, the output response of the circuit is partitioned into a minimal number of fragments, and a seed is computed for every fragment.
