Abstract

Some of Philips' industrial experience arepresented in this paper on defect-oriented testing ofmixed-signal ICs. Case studies on analog circuit blocks intwo automotive mixed-signal ICs are described. This isdone to demonstrate the potential of the defect-orientedtesting approach in the industrial test development for testcoverage improvement with simple industrial tests. It hasbeen shown that, in addition to the conventional function-orientedtests, the test coverage of bridging faults can besignificantly improved by some simple tests derived byusing the defect-oriented testing approach.
