Through our cooperation with Eberspächer Electronics, Warwick offers the FlexRay analysis tool Caromee. This tool

• is an acquisition and analysis program for network data.
• can be efficiently integrated in the vehicle development process.
• is simple to operate.
• can be individually enhanced by anyone.
• accompanies the entire vehicle development process.
• is very cost-effective.
• supports individual evaluation functions.
• is proven in production.
• works effectively with large volumes of data.
• has open interfaces in various directions.
• supports FlexRay and CAN.
• permits connection of interfaces from different manufacturers.
• has professional support.

With Caromee, guided by a wizard, you can carry out measurements on a CAN or FlexRay cluster with no great configuration effort. The wizard leads you through the configuration of Caromee in just a few steps. In the first step, you select which hardware interface is to be assigned to which Caromee bus.
In the second step, you can allocate a bus to a database.
These two steps are already enough to enable you to take measurements of a cluster. If, however, you want to record data, you can extend the configuration in a further step, guided by the wizard. It is even possible, as an option, to add a trigger to the configuration, and have it actuated by a button, for instance. Experienced users can, of course, create a measurement configuration quickly without the wizard.

The MessageViewer application, which the wizard opens when it starts up, provides comprehensive functions to present messages in a list. There are separate columns for information such as index, bus, time, relative time, last occurrence, sender, receiver, decoding, message, ID and data content. Convenient navigation functions for the message lists make it easier to work with the lists, which can be very long.

If databases have been stored for the various busses, you can quite easily display the individual signals of a message in graphic format. Clicking on a message and selecting one or more signals opens the Diagram Editor. Time-correlated, graphic representation of different signals, even signals from different busses, is possible. Signals may be presented together in one diagram, or in separate graphics.

Time differences can be measured from the graphic display of the signals. In a major cluster with several CAN and FlexRay busses, you will often want to concentrate on just one bus. With Caromee, the single-bus view is easy to find. Double-clicking on the bus, and then clicking to activate the filter, narrows the display down to the selected bus. Sophisticated filter functions that take effect at bus level, message level or even bit level are also part of Caromee.
