This paper presents a novel approach to extending the life of current-based test techniques for the detection and diagnosis of bridging defects. Called C&#x0394;IDDQ (Complementary &#x0394;IDDQ), this approach combines a modified test pattern generation with a simple post-processing of I<sub>DDQ</sub> measurements (namely additions and subtractions) such(More)
In this paper, we propose a new role for functional testing. We show that it can be used to optimize test sets in terms of test time and automated test equipment (ATE) memory resources, or to increase coverage. We also propose to ease the generation of functional test patterns, by reusing data sequences initially generated with system-level tools for(More)
In this paper we present a new technique called Captureless Delay Testing Points (CDTP). This technique allows the detection of delay faults left uncovered by launch-on-capture transitions, with top-off random launch-on-shift patterns that do not require fast switching scan enable signals. The CDTP random patterns are internally generated, requiring(More)
In this paper, we present improvements to a diagnosis method for bridging faults combining three different data sources. The first data source is a set of I<sub>DDQ</sub> measurements used to identify the most probable fault type. The second source is a list of parasitic capacitances extracted from layout and used to create a list of realistic potential(More)
