A fault constitutes a deviation of normal internal system states or signals. Such deviation could lead to the generation of wrong results, but it could also be masked by the current system state.

Abstract
Due to the increase in popularity of mobile devices, it has become necessary to develop a low-power design methodology in order to build complex embedded systems with the ability to minimize power usage. In order to fulfill power constraints and security constraints if personal data is involved, test and verification of a design's functionality are imperative tasks during a product's development process. Currently, in the field of secure and reliable low-power embedded systems, issues such as peak power consumption, supply voltage variations, and fault attacks are the most troublesome. This chapter presents a comprehensive study over design analysis methodologies that have been presented in recent years in literature. During a long-lasting and successful cooperation between industry and academia, several of these techniques have been evaluated, and the identified sensitivities of embedded systems are presented. This includes a wide range of problem groups, from power and supply-related issues to operational faults caused by attacks as well as reliability topics.
