Abstract: Using pseudo-random sequence for testing stimulus,K-dimensional feature space can be obtained by calculating the cross-correlation function of input and output sequence.The Circuit Under Test(CUT) on the basis of feature space can be analyzed and estimated.It is proved that the method is simple and feasible,and it can increase the efficiency and accuracy of test.This method can be applied in the mixed-signal circuits test and in the Built-In Self-Test(BIST).
Key words: pseudorandom testing, cross-correlation function, mixed-signal circuits, Built-In Self-Test(BIST)
