INERTE: Integrated NExus-Based Real-Time Fault Injection Tool for Embedded Systems
نویسندگان
چکیده
Software implemented fault injection techniques (SWIFI) enable emulation of hardware and software faults. This emulation can be based on debugging mechanisms of general purpose processors [1] or in special debugging ports of embedded processors [2]. A well-known drawback of existing SWIFI tools rely on the temporal overhead introduced in the target system. This overhead is a problem when validating real-time systems. This paper presents a new SWIFI tool (INERTE) that solves this problem by using a standard debug interface called Nexus [3]. Using Nexus, system memory can be accessed at runtime without any intrusion in the target system. Thus, INERTE is able to inject transient faults without any temporal overhead.

Modeling Time-Triggered Architecture Based Real-Time Systems Using SystemC
This paper proposes a SystemC based extension for the modeling of TimeTriggered Architecture (TTA) based real-time embedded systems. The extension called Executable Time-Triggered Model (E-TTM) supports the time-triggered model of computation and provides a time domain deterministic modeling framework based on SystemC. E-TTM can be used from the architectural design phase to support early funct...
متن کاملAn RTOS-based Fault Injection Simulator for Embedded Processors
Evaluating embedded systems vulnerability to faults injection attacks has gained importance in recent years due to the rising threats they bring to chips security. The task is particularly important for micro-controllers since they have lower resistance to fault attacks compared to hardware-based cryptosystems. This paper reviews recent embedded fault injection simulators from literature and pr...

Currently, computer-based control systems are still being implemented using the same techniques as 10 years ago. The purpose of this project is the development of a design framework, consisting of tools and libraries, which allows the designer to build high reliable heterogeneous real-time embedded systems in a very short time at a fraction of the present day costs. The ultimate focus of curren...
متن کاملModel-based development of fault-tolerant real-time systems
The design of fault-tolerant real-time systems is a complex task. The system must not only satisfy real-time requirements, but it must also deliver the specified functionality in the presence of both hardware and software faults. To achieve fault-tolerance, the system has to use redundancy. This redundancy is usually achieved by replicating hardware units and executing the application within a ...
متن کاملA Software Fault Injection Tool on Real-Time Mach
Ensuring that a distributed real-time system with strict dependability constraints meets its prescribed speciication is a growing challenge that confronts software developers and system engineers. This paper reports on a software fault injection tool, called SockPFI, for testing the fault tolerance and timing behavior of distributed real-time applications. SockPFI, developed on Real-Time Mach, ...
