Abstract

Studying cyber-physical system (CPS) for a given network protocol and processor schedules is a challenging task. This investigation illustrates the role of TrueTime a MATLAB package for simulating CPS encapsulating information on processor schedules, and network protocols. Properties of CPS such as temporal behaviors, performance and stability can be studied using the TrueTime tool. Furthermore, these simulations can be used to benchmark design and propose design alternatives. The procedure to use the toolbox for simulations and instantiate various blocks to study CPS is illustrated in the paper. Finally, an illustrative example has been presented of CPS simulation with wireless network. Our example demonstrates that TrueTime is a useful tool for studying CPS performance, timing behavior, schedulability analysis, and studying suitable network protocols.
