Fault Injection Software Tools and Robu...

In the design of measurement systems we face the fact that parameters are subject

to (measurement-) uncertainties.  Additionally, components may behave entirely di erent from what is speci ed, which is then considered a fault.  Consequently, both uncertainty as well as probability  of  failure  should  be  considered  in  education  on  robust  design  and  reliability.   In this paper we present a teaching concept based on hardware fault injection using a simple level sensor system as an example.  Learning objectives are faults, errors, failures, false alarms versus misses as well as advantages and disadvantages of redundancy.
