Abstract
This paper presents an accelerated test points selection method for circuits designed by a full-scan based BIST scheme. In order to speed up the test points selection method based on cost minimization, and reflecting random pattern testability, we introduce three techniques, the simultaneous selection of plural test points, the simplified selection of test points by the cost reduction factor, and the reduction of the number of test point candidates. We implement a program based on the proposed method and evaluate its efficiency experimentally using large scale circuits (26 k-420 k gates).
