FAULT TOLERANCE EXTENSIONS OF TrueTime PACKAGE FOR DISCRETE SYSTEMS SIMULATION

The general objective of this project is to create an environment for discrete event simulation to assess safety properties of databuses used in real-time applications, especially in automotive and avionics industries. In this paper, we describe several extensions of the TrueTime simulator, beginning with the development of the fault injection model and incorporating it into the simulator using Matlab S-functions in C++. We also discuss an interface to TrueTime to simulate hardware faults via Matlab/Simulink with the use of HDL/Spice tools and high-level object-oriented programming models, which simulate software and hardware faults. Finally, we are suggesting graphical user interface extensions to TrueTime using Lab VIEW that prove necessary for efficient experimental data generation, gathering and analysis.
