VLSI Analog Circuit Fault Diagnostic Correlation Coefficient Analytical Method
Zhiming Hu, Yongle Xie, Tianyi Li · 2009
In the paper, an approach based on digital signal processing for VLSI analog circuit fault diagnosis is presented. We firstly filtered the test response by cosine modulation filter banks, then computed energy and correlation of all the sub-band filtering sequence to distill digital character of analog response. The experiment based on international benchmark circuit showed that computing correlation of sub-band filtering sequence suited to diagnose hard fault and soft fault.
