In real-time safety-critical systems, it is important to predict the consequences of specific faults in databus logic and driver software on the safe operation of a databus. For this purpose we have developed a test-bench based on the TrueTime simulator extended by adding a fault injection capability, with new network models and fault modeling strategy. Faults are simulated by disturbing specified parameters of the databus model. In this paper, we present the modeling approach, the fault injection scenarios, and illustrate it with examples of the impact of the simulated faults on data throughput, message latency and bus scheduling for CAN and TTCAN networks.
