Functional Overview<\/strong><\/h2>
Currently users face the following scenarios that require Ethernet communication simulation during software development:<\/p>
Multi-ECU communication for functional verification: real ECUs are not fully developed;<\/li>\n\n
Simulating complex communication conditions and faults to test the robustness of the system: it is difficult to construct such scenarios for real ECUs;<\/li>\n\n
Automotive software upgrade to verify compatibility with other versions: different versions of the real ECU are required;<\/li>\n\n
ECU communication from different vendors, collaborative validation: inconvenient for different vendor ECUs to collaborate;<\/li>\n\n
Other development\/testing issues.<\/li><\/ul>
Based on the above user problems, TSMaster developers have developed an Ethernet communication simulation module for users. The simulation module uses the Ethernet communication protocol and is designed to highly simulate the communication between real ECUs, providing users with a comprehensive and effective solution.<\/p>
The Ethernet communication simulation module simulates the process of real ECUs sending and receiving communication messages to verify the accuracy and stability of the software in handling different types of messages. The module can flexibly simulate various communication failure scenarios to meet the system robustness testing requirements. For example, it simulates network delay, packet loss, error message injection and other faults to help developers test the software's ability to cope with complex communication conditions.<\/p>

Figure 13: Data field 2<\/figcaption><\/figure><\/div>
4.4 Fault simulation<\/strong><\/p>
4.4.1 Simulating network delays<\/strong><\/p>
In the Ethernet communication simulation interface, modify the value of Interval(ms) to set the period of message sending; modify the value of Phase(ms) to set the phase of message sending; as shown in the following figure, set the sending period to 500ms and the sending phase to 100ms, so as to simulate the network delay.<\/p>
In the Ethernet communication simulation interface, if you do not check the corresponding message, it will not be sent during the simulation, thus simulating packet loss.<\/p>
In the Ethernet communication simulation interface, you can modify the Data field and set the error value to simulate the sending of data error messages.<\/p>
Figure 16: Editing the Data field<\/figcaption><\/figure><\/div>
In this section, it will be shown how to call the API to realize a series of functions, covering operations such as checking the box to send a message, setting the message sending period, setting the message data value, and starting the emulation.<\/p>
5.2.1 Initializing the environment<\/strong><\/p>
Refer to sections 4.1 and 4.2, and follow the guidelines therein to complete the operations of importing Ethernet database, selecting the corresponding channel, and checking the configuration items.<\/p>
5.2.2 How to call the APIs<\/strong><\/p>
Add C applet editor in [Design] -> [C Applet] module. Once added, the editor supports calling all APIs mentioned in section 5.1.<\/p>
Figure 17: Adding the C Applet Editor<\/figcaption><\/figure><\/div>
In the C applet editor, there are various types of events, and the following is an example of a program start event. You can add a program startup event by right-clicking on it and writing the required code logic in the code area corresponding to the event. In this way, the code logic will be executed automatically when the program starts running.<\/p>
Figure 18: Adding a program startup event<\/figcaption><\/figure><\/div>
5.2.3 Code descriptions<\/strong><\/p>
Edit the following sample code in the new program startup event code area, which functions to periodically send a specified message and dynamically modify the message's send value during the sending process. The specific logic is as follows:<\/p>
1) Check the PDU message named \"PDUTXDemo1_0\" to make it active.<\/p>
(2) Parameterize the \"PDUTXDemo1_0\" message, setting its phase to 0ms and its transmission period to 500ms.<\/p>
3) Set the value of the signal named \"SignalDemo1_0_0\u2033 to 1.<\/p>
4) Start the Ethernet communication emulation and begin the periodic sending of messages.<\/p>
5) After the simulation is started, it enters into a loop operation and sets the value of the signal named \"SignalDemo1_0_0\u2033 to 0 and 1 alternately.<\/p>
6) Stop the simulation of Ethernet communication simulation after ending the cyclic operation.<\/p>
<\/figure><\/div>
5.2.4 Compilation and execution<\/strong><\/p>
In the C applet editor, when you click the \"Compile\" button, the editor will immediately start compiling the code. After the compilation is completed, the system will give you a clear indication of the compilation result, displaying \"Compile Successful\" or \"Compile Failure\".<\/p>
If you are prompted with a compilation failure, you need to carefully review the specific prompt messages, locate and modify the errors in the code according to these messages, and then try compiling again.<\/p>
If prompted for a successful compilation, the editor will automatically generate an executable file corresponding to the code, which can be subsequently run to verify the program's functionality.<\/p>
Figure 19: Compiling the code<\/figcaption><\/figure><\/div>
Since the Ethernet communication simulation startup is based on the TSMaster startup connection, it is important to ensure that the TSMaster has been started and the startup connection operation has been completed before executing the executable file generated above. Only when TSMaster is in the startup connection state, the execution of the executable file will not cause any abnormal operation.<\/p>
In the C Applet Editor screen, click the \"Run\" button to execute the executable file.<\/p>
Figure 21: Running the compilation file<\/figcaption><\/figure><\/div>
5.2.5 Implementation results<\/strong><\/p>
After launching the executable file, you can view the relevant information in the Ethernet communication simulation interface. The content presented in this interface is exactly the same as the settings made by calling the API in the sample code, specifically including: the corresponding message that has been checked, the set period of sending the message, the specific value of the signal value in the message, and you can also see that the Ethernet communication simulation has been successfully started.<\/p>
At the same time, in the [Ethernet message information] interface, you can observe the message being sent. The data value in the message is in a cyclic state, which is exactly the effect of the sample code by cyclically setting the signal value to 0 and 1 alternately. When the loop is finished, the Ethernet communication simulation is stopped; thus, the sample code completes the whole execution process.<\/p>
