摘要

In spite of significant efforts in circuit testing, sequential circuit testing has remained a challenging problem. Existing test solutions like scan methods are proposed to facilitate Automatic Test Pattern Generation (ATPG), however, these methods suffer from large area and delay overhead. In this paper, a new hybrid history-based test overlapping method is presented to reduce test time in scan-based sequential circuits while almost no extra hardware overhead is imposed to the circuit. Experimental results show 30% reduction on average test time in comparison with existing works.
