The latest version of EB (Elektrobit)’s EB tresos Busmirror cluster emulation tool extends the capability of performing real-time cluster emulation from FlexRay into CAN networks as well. The cluster emulation offering is complemented by the new EB 2100 hardware interface. An open-programming interface allows custom-developed software modules to be integrated into the EB tresos Busmirror 2010.a or the EB 2100. Developers can now use the same tool for both FlexRay and CAN simulations. The EB 2100 hardware can also be used for time-critical applications in cluster emulation. Due to the difficult requirements of safety-relevant systems for FlexRay, real-time-capable hardware must work in synch with the FlexRay bus. Thanks to open programming interfaces, the solution is easily integrated into different host systems such as Windows or Linux.
