Fault Injection (FI) is a method used to quantify the reliability and resilience of a system by assessing the system's ability to detect, locate, and/or mitigate fault occurrences. At the architecture level, targeted bit flips at specific times and locations can help quantify the response of a running application to unwanted changes in state and memory values. FI campaigns of this type can be performed on the target hardware virtual implementations of the target device. In this paper, we present a survey of Quick EMUlator (QEMU) based FI techniques. After discussing the various techniques proposed by academia and industry, we classified them into categories and compare their attributes. This review will help researchers understand the capabilities and limitations of using the QEMU emulator for FI-based system reliability analysis. Additionally, we identify the gaps in existing techniques and propose opportunities for extensions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
