Device Injects FlexRay Faults

June 13th, 2007

TTAutomotive announces its second generation TTX-Disturbance Node, a device that helps engineers validate FlexRay networks and FlexRay-based applications in the lab and in the vehicle. With the new TTX-Disturbance Node, network designers and test engineers can achieve unprecedented test coverage for vehicle systems that are based on FlexRay. TTX-Disturbance Node is used for testing the robustness of FlexRay networks and physical layers, from early prototype versions up to the start of production.

TTX-Disturbance Node provides all the necessary means to inject realistic network disturbances into a FlexRay-based system, whether simple, single upsets or complex fault scenarios. The device allows developers and test engineers to examine the robustness of the FlexRay network, as well as the effects of network faults on system behavior, and the fault handling capabilities of the system.

TTX-Disturbance Node provides the user with a powerful, fully programmable XML-based tool for establishing completely reproducible fault scenarios for distributed systems. The second-generation TTX-Disturbance Node allows injecting faults on the entire network under test, or to split the network and inject faults only in the communication nodes that are under test. It offers enhanced triggers and a graphical configuration tool, and it supports standard 10 Mbit/s data rates, as well as 5 and 2.5 Mbit/s.

Using XML-based fault scenario definitions, TTX-Disturbance Node provides the capability to design and perform complex, fully repeatable fault injection scenarios, making it the most versatile device for stressing networks. Various classes of faults are supported, thus allowing analysis of system behavior at the physical, logical, and application layers.

TTX-Disturbance Node provides a variety of new features, including enhanced trigger possibilities, modification of timing behavior of the FlexRay network, and generation of valid and invalid frames. It can be used effectively to test the stability and marginal behavior of the physical layer configuration.
