文摘This paper analyzes structural characteristics of signal vectors in combinational circuits with RTL description. Then, this paper presents the concept of the Basic Similar Circuit (BSC), a circuit constructed by compressing the bit-width of vectored vectors in the original circuit. BSC shrinks the scale of the original circuit, thus improving the ATPG efficiency. Test patterns are derived from adjustment and assembling of precomputed sub-circuit test sets. Based on the deterministic algorithm, the ATPG method presented in this paper combines deterministic algorithms and undetermined methods.
