Fidalgo, André V.Gericota, Manuel G.Alves, Gustavo R.Ferreira, José M.2014-04-012014-04-0120061-59593-479-0http://hdl.handle.net/10400.22/4293As electronic devices get smaller and more complex, dependability assurance is becoming fundamental for many mission critical computer based systems. This paper presents a case study on the possibility of using the on-chip debug infrastructures present in most current microprocessors to execute real time fault injection campaigns. The proposed methodology is based on a debugger customized for fault injection and designed for maximum flexibility, and consists of injecting bit-flip type faults on memory elements without modifying or halting the target application. The debugger design is easily portable and applicable to different architectures, providing a flexible and efficient mechanism for verifying and validating fault tolerant components.engFault injectionReal time systemsOn-chip debugconference object10.1145/1150343.1150397
