Break fault model and fault collapsing analysis for PLA's
Gwo‐Haur Hwang, Wen-Zen Shen · 2003
The behavior of break faults in PLAs is analyzed and a fault collapsing technique for the faults is presented. From the behavioral analysis, two patterns are needed to detect a break fault. By the fault collapsing technique, the number of break faults is reduced from 2*( Hash device)+( Hash output) to less than 2*( Hash input+ Hash product)+( Hash output). Experimental results show that, for 56 benchmarks, the number of break faults after fault collapsing is reduced to 18.37%.>
