Abstract :
Conventional software scan diagnosis using Electronic Design Automation (EDA) tools and hardware diagnosis using frequency mapping technique, are established methodologies for broken scan chains fault isolation. This work proposes a diagnostic workflow that integrates both methodologies to enhance accuracy and reduce turnaround time for debug. Experimental results are presented to demonstrate the effectiveness of this workflow for systematic fail dies analysis.
