Multiple voltage is an effective dynamic power reduction design technique commonly used in low-power ICs. To the best of our knowledge, there is no reported work for diagnosing multiple-voltage enabled ICs, and the aim of this paper is to propose a method for diagnosing bridge defects in such ICs. By using synthesized ISCAS benchmarks, with realistic extracted bridges and a parametric fault model, this paper investigates the impact of varying supply voltage on the accuracy of diagnosis and demonstrates how the additional voltage settings can be leveraged to improve the diagnosis resolution through a novel multivoltage diagnosis algorithm. In addition, it also identifies the most useful voltage settings to reduce diagnosis cost by eliminating tests at certain voltage setting using the proposed multivoltage diagnosis approach, thereby achieving high diagnosis accuracy at reduced cost. © 2009 IEEE.
