NETCARBENCH: a GPL-licensed benchmark generator for automotive communication systems

NETCARBENCH

that is being developed at INRIA since 2007, is a GPL-licensed software that generates automotive message sets according to a set of user-defined parameters. NETCARBENCH allows to generate realistic sets of messages (both frames and signals) that can be used for comparing algorithms or making design choices.

NETCARBENCH is especially useful early in the design cycle when the real message sets are not yet available: for the embedded system architecture design or for assessing the maximum load that can be achieved on a certain bus. Another interest of NETCARBENCH is that the message sets it generates can be communicated, overcoming the confidentiality requirement one has with real sets of messages. In practice, NETCARBENCH is used to design and configure CAN and FlexRay communication systems (see

for some articles including results obtained using NETCARBENCH).

Note also that the freely available simulation and analysis tools RTaW- Sim and NETCAR-Analyzer can read the NETCARBENCH format, so that it is possible to perform worst-case response time analysis, simulate and perform fault injection directly on the NETCARBENCH generated networks.

All feedback and new feature requests most welcome, Thank you,
