Paper Title:
Detection of Crosstalk Faults in Digital Circuits by Testability Evaluation
  Abstract

The increase in dense interconnect as well as the clock frequency of digital circuits has led to an increasing number of crosstalk faults. A new test approach for crosstalk faults in digital circuits is presented in this paper, the approach aims at the faults of crosstalk induced pulse, uses controllability and observability measures of the signal lines to produce the test vectors of crosstalk faults. Choose a lot of paths from the fault site to the primary outputs of circuit, and carry out forward tracing and backward tracing, until every signal line is assigned a logic value and no conflict arises. Experimental results on a lot of digital circuits show that the test approach proposed in this paper can generate the test vectors of crosstalk faults, and can obtain high fault coverage.
