Nowadays, it is possible to observe a growing number of embedded systems in applications ranging from simple consumer to safety critical uses. To cope with the actual situation, new test methodologies, fault tolerance techniques, as well as new paradigms that are capable of guaranteeing the robustness and reliability of the systems, have been developed. Therefore, it can be said that robustness and reliability represent two of the most important challenges for the design of integrated circuits and systems. Further, it is important to highlight that the environment hostility where embedded systems can be found has significantly increased due to different types of interference caused by several kind of sources. In this context, Electromagnetic Interference (EMI), that can interfere or degrade the proper behavior of the circuit, represents one of the principal problems when aiming for reliable and robust embedded systems. Therefore, it is necessary to introduce design techniques directly aimed to achieve Electromagnetic Compatibility (EMC), thus eliminating or reducing the effects of EMI to acceptable levels. This work proposes a new hardware-based fault injection platform able to inject Power Supply Disturbances (PSD) into integrated circuits and systems according to the IEC 61000-4-29 normative. The developed platform can be used as a support mechanism during the development of PSD-tolerant embedded systems. Moreover, it is important to note that the new fault injection platform represents a viable and easy-to-configure alternative that can be used to evaluate the robustness and reliability of embedded systems.
