2 2 AUTOmotive bus systems System Overview Analyzing Networks in all Development Phases Control units are a fundamental part of electronic systems in vehicles. In order to test their function effectively, they are tested as early as at the end of individual phases in the development process. With its Caromee software, Eberspächer Electronics has developed a tool for this purpose that quickly logs and evaluates measured data and displays it clearly. Users benefit from numerous display options of Caromee, which make configuration and system monitoring and evaluation especially easy and effective. As the solution for the CAN, FlexRay, LIN, MOST and Ethernet bus systems, the software processes various types of data input. The combination of the basic Caromee software and the FlexCard interfaces provides all required basic functions for measuring and analyzing networks. Features such as numerous open interfaces permit ideal adaptation to your individual requirements and offer convincing cost efficiency. The Eberspächer Electronics solution is over 50% cheaper in comparison to the competition. The analysis program is linked to a test setup via the interface cards available in many versions from Eberspächer Electronics. As the interface between the test computer with Caromee software and the data bus, the FlexCard product family ensures reliable transmission of all information from the respective bus systems. Depending on their use, the interface cards are either permanently installed in the computer or used as a mobile solution together with laptops. Drivers for Windows, Linux and LabVIEW safeguard the application in everyday testing, even with different operating systems and programming languages. PC system Caromee FlexCard CAN / FlexRay

4 4 AUTOmotive bus systems Network Analysis Logging and Evaluating Data Effectively A large volume of measured data accumulates and must be evaluated quickly and in a targeted manner during control unit testing in the product development phase or in vehicle testing. Only in this way can errors be remedied easily and adaptations be performed on the control unit or in the vehicle network. In order to test and evaluate data easily, Eberspächer Electronics offers an effective logging tool with the Caromee analysis software. Features such as the comprehensive vehicle interfaces for various bus systems permit simple adaptation to suit your requirements. This not only gives you a quick overview of the data of relevance to you, but also perceptibly lowers your development costs. Without additional, often complex and expensive test phases, data can be examined for errors with Caromee and the corresponding changes can be made. be evaluated and manipulated this way using custom-designed algorithms. They are not fixed to one bus system for data transfer. As a universal measuring framework, Caromee processes information from CAN, FlexRay, LIN, MOST and Ethernet bus systems both online and offline. In order to use the comprehensive data analysis of Caromee with different hardware products, the software can be readily adapted to existing components. Benefit for you: This allows you to integrate the PC tool into your existing process chains without difficulty and even define special evaluation functions to match your specifications. This is made possible by the integrated scripting function. In addition to the stored command sets for data processing, even complex signal and message packages can Caromee ETHERNET

5 AUTOMotive bus systems 5 One Software Many Functions Data Analysis Overview of Large Data Volumes Extensive and complex networks in test vehicles produce large volumes of data. A clear depiction is important for evaluating this data online or offline. With the Analyzer application, Caromee therefore offers the option of depicting messages as a list view, supplemented by convenient navigation, filtering and search functions. A diagram display also permits graphic presentation of signals time correlating and also from different busses. If data from a vehicle network is collected over an extended period, this data can be evaluated with the journal view of Caromee. One advantage of this depiction: Certain events, such as error frames or terminal-status changes, are easy to determine because they are clearly identified. Thanks to the analysis filter, it is also possible to search through and filter the data for certain events or to store only certain information. Log data quickly online In network analysis, it is often necessary to perform online measurements on a cluster. Caromee therefore features a Wizard for polling the data. With this Wizard, you can perform measurements on a CAN-, FlexRay-, LIN-, MOST- and Ethernet cluster without great configuration effort. Since the Wizard automatically opens the Analyzer application, even extensive messages can be shown in a list. Numerous filtering functions from the bus level down to the binary level simplify an overview of the measured values. Customization As an open measuring framework, Caromee can be expanded via numerous interfaces. The software s dynamic plug-in concept also permits expansion by additional measuring equipment interfaces. Additional measuring equipment can be connected easily via a programming interface. The development of additional write and read formats is also possible, as well as external control through individual scripts or programs and the COM automation interface. Caromee can also exchange messages with other programs. Integrated Wizards simplify the custom configuration of the software.

7 AUTOMotive bus systems 7 caromee Topology editor Defining Data Flow and Functions In order for you to be able to evaluate your data, signals and messages with Caromee, the software first must be adapted to your specific test setup. This is accomplished quickly and easily with the integrated Topology Editor. A clearly structured depiction allows you to select the corresponding bus system for data analysis without difficulty. Functions are linked for example, two hardware channels with the logging block and the message view (trace) in the Analyzer via simple graphic elements corresponding to the data flow model. These are already stored in the Windows-based view of the Topology Editor and therefore can be easily integrated into the visual test view. This allows Caromee to be configured quickly and without complications, even for extensive vehicle networks for fast measured results and cost-efficient work.

8 8 AUTOmotive bus systems Caromee Analyzer Network data trace in List Form In order to obtain a rapid overview of messages in vehicle networks during a test run, Caromee features the Analyzer application. This allows you to call up the data traffic in your network in the form of a clearly structured list. You can use numerous stored functions to adapt the list view to your specific requirements. The Analyzer is based on an intuitive user prompting system: Its ease of use will help you to select individual messages rapidly. This provides information on individual signals in a clearly structured framework. Comprehensive sorting and filtering functions in the Analyzer assist you in your data analysis from the bus level, through the message level and all the way down to the binary level.

You can choose from several views. For example, the time-correlated presentation of different signals in one or more diagrams is possible even if they come from different network busses. Another benefit of the graphic overview: Like on an oscilloscope, the time sequence of the signal contents can be captured rapidly. This provides you with a convenient overview of your data traffic in the network, allowing you to adapt it quickly and without complications if necessary.

10 10 AUTOmotive bus systems Caromee JournalViewer Overview of an Entire Measurement Caromee is capable of clearly depicting all data collected in the vehicle over an extended period as a journal in JournalViewer. The created network analysis log files form the basis for the individual journals. This provides an overview of important parameters. They include events, terminal-status changes or error frames, for example. You can decide which of these parameters are to be stored as early as when defining the log data for a journal. Other features of the JournalViewer include the comprehensive analysis tools, which allow you to search for and filter out messages. Since certain events often are associated with numerous further conditions, selecting individual signals or data items therefore suffices to allow conclusions to be drawn about the entire network. Additionally, you can specifically cut out individual areas from journals and evaluate them in detail or prepare them as statistics. The JournalViewer also logs idle phases in bus systems for an integrated analysis of your network in the vehicle. Overall, the JournalViewer saves time in error analysis and therefore reduces costs for the analysis.

11 AUTOMotive bus systems 11 Caromee Network Depiction View of the Entire Vehicle Network In tests on vehicle networks, it is often important to overview more than individual sections or control units. Therefore, evaluating the entire data traffic in the vehicle requires an overview that depicts the entire network with all control units. With the network depiction feature*, Caromee includes the suitable application for this. It easily provides you with an overview of your system layout including all control units used and the complete data traffic. Caromee thereby offers you effective tools to enable analysis of your network, ranging from the Analyzer for individual messages, through the JournalViewer for the overall measurement to the network depiction for the entire vehicle individually configurable and with the suitable depiction for every development step. * Available from Q2/2012

12 12 AUTOmotive bus systems Caromee: Programming and Expanding User-Defined Scripts Caromee scripting allows you to adapt the software specifically to suit your requirements. You can therefore use your own algorithms to check complex signal and message packages in networks. The platform-independent Lua script language ensures a simple introduction and trouble-free further development of test criteria. Your message and signal logs can be evaluated quickly thanks to comprehensive filters, message generators and the option of time-controlled intervention in data analysis by means of timers supported by a high data throughput rate for short logging cycles. For users already in possession of CAPL scripts, Caromee includes a converter to Lua format to assist with the migration.

13 AUTOMotive bus systems 13 Ethernet as the New Standard Higher Data Rates Caromee supports numerous bus systems with CAN, FlexRay, LIN and MOST. In addition to them, Ethernet as a new standard for vehicle networking will find its way into future vehicle developments. The benefit: Ethernet does more than just enable data transfer between a computer and a vehicle access point. In fact, Ethernet can also be used as a data bus and therefore to connect control units in the vehicle and to evaluate data. Since transfer rates of up to 100 Mbit/s can be realized with Ethernet, a significantly higher transfer of signals and messages in a shorter time can be achieved compared to a CAN or FlexRay bus. Another benefit: An Ethernet data line with the physical layer BroadR-Reach used in the vehicle produces only very few electromagnetic emissions. It is also very insensitive to external interference. PC system Caromee ECU 1 Ethernet / BroadR-Reach In order to assist you the best way possible with the new bus technology and all of its challenges, it has recently become possible to use our Caromee software tool to measure and evaluate Ethernet data as well. This means the following for you: Independently of the bus system, you will continue to be able to implement all analysis tasks in vehicle networks with the familiar ease and speed in future.
