A Software Fault Injection Tool for Evaluation of the Dependability of Onboard System

With the applications of computers being more wide,many traditional fault injection techniques and tools are confronted with new challenges in some of new fields.In this paper,a new software implemented fault injection tool SFIOS,which aims at evaluation of the dependability of onboard system developed by our research group is introduced.This is an easy use tool when,location and event are adopted as fault trigger conditions.Using this tool,not only faults close to the realistic environment onboard system runs can be easily emulated,but no modification to the onboard application tasks is needed.It has minimum interference with tasks running on the onboard system.Experimental results show there are many advantages and potential using the fault injection tool to evaluate the dependability of onboard system.
