A Method to Locate Parametric Faults in Analog Integrated Circuits
模拟集成电路参数型故障定位方法

Aiming at the problem of testing parametric fault in analog integrated circuits,an approach based on power spectrum correlation analysis for diagnosing parametric faults is presented.After wavelet filter-banks' filtering,the coherence function of the sub-band response sequence is computed.Subsequently,correlation analysis is imposed upon the power spectrum described by the coherence function sequence.As a result,not only can extracting the digital signature of the parametric fault be completed,but also the ...
