Simulation and Analysis
Residual Bus Simulation (RBS)
Functional Simulation based on Matlab/Simulink

With the Ixxat simulation solutions you can simulate the communication behavior of missing components (ECU’s) in your communication network. Communication simulations (RBS) are configured based on network description files with an easy to use tool. There’s no own coding required. Functional simulations can be implemented by scripts, C user code or MATLAB/Simulink models. Standalone or PC based simulation – that’s up to you. You don’t want to waste time – in that case the Ixxat simulation solutions are the right choice for you.

PC-based or standalone approach?

PC-based simulation can be done by using either PC interfaces, FRC-EP170/190 or CANnector. The application itself runs on a PC (as for example CanEasy). This economic approach is flexible and easy to implement, but has – due to several layers in between – limited real time processing capabilities.

Applications with high real time demands – e.g. residual bus simulation – can directly be executed standalone on the FRC-EP 170/190 or CANnector platforms. Direct connection to the buses and powerful local processor performance enables low latency transmission and real time processing. The configuration of the application and devices is done easily via Ixxat ACT.

Application examples
