C-Sim - the C language enhancement for discrete-time simulation

The paper presents the C-Sim simulation environment, which enables the execution of several processes in an interleaved mode using the global simulation lime concept. C-Sim was used within the EU/IST project Fault Injection for Time Triggered Architecture (FIT) to build a simulation model of TTP/C protocol based real-time embedded computer system in order to verify its dependability through fault injection.
