– Factory automation
– Robotics
• Main benefits
– Low cost– Good resilience to electromagnetic interferences
– Good real-time features

• CAN has been traditionally used in applicationsin which faults can have very negative effects
• It is mandatory to evaluate the capacity ofthese applications for dealing with faults

A widely used technique to evaluatehigh -dependable systems is fault injection ,
which allows to observe efficientlythe response of the system
when errors do occur

• Low spatial resolution
• Low time resolution
• Traffic restrictions
• Modifications on the nodes
IntroductionLimitations of previous CAN fault-injection systems

Why is it so important to provide a fault-injection
system that does not show those limitations ?

GOAL
To build a new fault-injection infrastructure
capable of reproducing complex fault scenarios and,
thus, to test the response of CAN-based applications
and protocols when these faults do occur
Introduction

To achieve this goal we developed a
physical fault-injection system called sfiCAN

Conclusions
We achieved the goal , we developed a physicalfault-injection system capable of reproducing
complex fault scenarios to test the response ofCAN-based applications and protocols

Conclusions
• Fault model
– Global/local faults
– Bit granularity
– Transient, permanent and intermittent
– Simple/complex scenarios
• Semantic faults to some extent
