A testing scheme for crosstalk faults based on the oscillation test signal

Abstract

A test scheme for the crosstalk fault based on the oscillation signal is proposed. It uses an oscillation signal applied on an affecting line and detects induced pulses on a victim line if a crosstalk fault exists between these two lines. It is simple and eliminates the complicated timing issue during test generation for the crosstalk fault in the conventional approaches. The test generation and fault simulation based on the scheme are described. Experimental results are also presented to show the described test generation procedure is effective in generating test patterns for this scheme.
