4 Stimulation M also offers you a number of functions for stimulating M devices or systems. Without programming effort, the NetworkMaster that is integrated in lets you properly startt up a device for individual device tests. 2 Interactive Analyses and Tests M lets you analyze all of the M data. Along with receiving the control and asynchrous channels, you can also receive synchrous dataa and M150 Ethernet packets (MEP). In addition, you have access to all hardware and network states such as Light & Lock and Configuration Status. 2.1 Analysis Examples: In M State- and Bus Statistics windows you can see at a glimpse the most important settings and the current state as well as the load of thee connected M ring. In the Trace window, you can observe the data sent over the control channel and asynchrous channel in M messages. For a clear representation, this data is interpreted with thee help of the function catalog. Segmented data transmitted over AMS or the M Highh Protocol can also be displayed with the integrated Combiner. Color highlighting of events based on static properties or dynamic analysis results makes it easier for you to visualizee the analysis of communication on the M ring. Various search and filter options offered directly inn the Trace window can assist a you in efficiently finding the desired information from the displayed data. The M System Viewer shows the M system with its ring structure and gives you an overview of the distribution of function blocks to your ECUs. Along with variouss statistical information, you can read off the loads of individual devices on the Retry Indicator. The M Central Registry window shows the contents of the system s description that is managed by the NetworkMaster of your system. The current description can bee conveniently checked against a reference registry. In addition, the windoww has a history that also lets you analyze previous states of the system description. The M FBlock Monitor gives information on the states of ECU applications. The view is built up with each additional piece of information transmitted over the M ring, without requiring any configuration effort by the user. But you can also get specific information on application states by setting the relevant tification in your ECU directly from the M FBlock Monitor. The Graphics window lets you display the response of selected signals s over time with flexible zoom and measurement functions. For example, youu can directly measure the time it takes from wake-up on the Electrical Control Line (ECL) until the M signal is activated or select signals on the application level from the function catalog for display. In addition, your analysis scripts can output the results in the Graphics window. You can individually design panels with a user-friendly editor, in order o to display your analysis results in optimal form online.

You can use the M Interactive Generator to send M messages and message sequences. Simply select them from the XML functionn catalog, set the parameters to the desired values and stimulate the ECU application at the presss of a button. You can create panels to control your multimedia devices which let you efficiently perform testing tasks or serve as a prototype for user interfaces. 7

8 The M Stress window lets you generate bus load on the control and asynchrous channels or stress your system with sequences of unlocks.

9 Figure 11: Stimulation from the Stress window or from panels 3 Automated Analyses and Stimulation You can automate analysis of the system with the help of the CAPL programmingg language. A CAPL de inserted in the measurement setup reacts to M messagess and systemm events. Forr example, it can be used to monitor timings or sequences and compute characteristic communication values. You can have a CAPL program show the results in panels, highlightt messages in the Trace window, or o write the results to files. Unlike user controlled visual analysis in the Trace window, this process is always reproducible. In addition to analysis tasks, you can also use CAPL to automate stimulations that need to be exceptionally reproducible or should react to events in your system as quickly as possible. For example, you can automatically start stress functions to check whether your system also behaves correctly in critical situations. Or you can stimulate the M ring with programmed message sequences. Previously recorded message sequences can also be fed into the ring with the help of the Replay block. In offline mode, you can use the same analysis programs to analyze pre-recorded log files. In addition, you can define conditions which immediately interrupt the analysis run when they occur o in offline mode. This gives you the option of playing even very large log files and analyzing specific critical situations inn the Trace window at your convenience. 4 Other Application Areas 4.1 M High Protocol (MHP) M offers you extensive MHP support: The MHP protocol observerr shows you, even in the case of segmented transmissions, a disassembly of the application data in the Trace window. Moreover, it outputs specific s references to protocol violations. In CAPL des in the t measurement setup, you also have access too the outputs of the Protocol Observer; this lets you automate MHP and application analyses. The automatic MHP receiver lets you poll extensive ECU data via AMS and receive the response r via MHP without having to implement a MHP data sink. 9

With this access capability M covers a whole series of application cases in the area of streamingg of multimedia data. This is described in detail in the application te M Synchrous Channel Access. A In the case of M25, independent of the Synchrous Boundary Control (SBC) that is set, all synchrous channels can be transmitted via USB to the PC, and in the other direction the PC can feed into the ring. In the case of M150, selection of the synchrous channels to be transmitted is via the Connection Labels. 5 Gateway Functionality M is also the right tool for your gateway development. Analysis of gateway propagation times and testing of signal routing are possible without difficulty. Furthermore, option M may be combined withh any of the options for CAN, C LIN, FlexRay and IP. For example, you can select which bus systems to access according to your precise needs. The time stamps of the events of alll buses are precisely synchronized, and so theyy reference a common time base. For example, if M is combined with CAN, you can examine the messages of both bus systems in a Trace window in a chrological view and analyze thee interrelationships. With analysis scripts, which then also have simultaneous s access to CAN and M messages and system states, you can definee automated start-up times, measure gateway propagation times or verify thee signal routing algorithms of your gateway. It is easy to analyze Gateway propagation times and testing of signal routing. Figure 13: Trace of a gateway measurement 10
