Abstract
Recent research has shown that tests generated without taking process variation into account may lead to loss of test quality. Using transition delay test, this paper analyzes the behavior of resistive bridge defect under the influence of process variation. The effect of process variation is incorporated by using three transistor parameters: gate length (L), threshold voltage (V th ) and effective mobility (μ eff ), where each follows Gaussian distribution. Through HSPICE simulations using a 65-nm gate library, this paper brings the following two contributions: firstly, it analyzes the delay behavior of bridge defect using all three transition delay classes to determine the most effective class of transition test that achieves maximum coverage in the presence of process variation. Secondly, recent research has shown that low voltage testing improves detectability of bridge fault, this work compares bridge resistance coverage using logic test and delay test at multiple voltage settings to identify the best voltage setting and test type for detecting resistive bridge defects.
