ABSTRACT
<p><b>Abstract</b>—Test generation procedures based on genetic optimization were shown to be effective in achieving high fault coverage for benchmark circuits. In this work, we propose a representation of test patterns for genetic optimization based test generation, where subsets of inputs are considered as indivisible entities. Using this representation, crossover between two test patterns <tmath>$t_1$</tmath> and <tmath>$t_2$</tmath> copies all the values of each subset either from <tmath>$t_1$</tmath> or from <tmath>$t_2$</tmath>. By keeping input subsets undivided, activation and propagation capabilities of <tmath>$t_1$</tmath> and <tmath>$t_2$</tmath> are expected to be captured and carried over to the new test patterns. Experimental results presented show that the proposed scheme results in complete stuck-at test sets and <tmath>$n$</tmath>-detection test sets for combinational circuits, even in cases where other procedures report incomplete fault coverages.</p>
