This paper proposes a real-time testing method for multilevel signal interfaces. It utilizes multilevel drivers that can modulate both the voltage and timing of an output signal, and multilevel comparators based on a dynamic threshold concept. The authors also consider the impact on test cost of the proposed system and compares that cost with a conventional binary test system.
