Automotive Ethernet test system automates testing
The Automotive Ethernet Tester is a further development of Ruetz’ own test platform to provide vehicle manufacturers and suppliers with a comprehensive test system for the new specifications. It supplements the manufacturer’s Ethernet Live Monitor, which focuses on error analysis of Ethernet data traffic. The AET generates different load and speed scenarios and records them with the appropriate data acquisition. The test suites contain various test cases as a basis for the respective test scopes. Currently available are test suites for Open Alliance TC8 switching, Automotive gPTP, 1722 and QAV. Test suites for QBV and other TSN functions are under development.
The test cases are script-based and are parameterized prior to a test run via a single configuration file that contains all relevant properties of the device under test (DUT). The DUT and the test cases can be easily configured via intuitive user interfaces. Users can select the individual test cases from a continuously updated database and combine them into a new test run by drag-and-drop.
The AET automatically saves the recorded data in a predefined folder structure. In addition, the test system provides an infrastructure for the complete recording of sent and received data. For analysis, the manufacturer provides an additional AET analyzer tool. It accesses the file structure and generates a result log from the recorded data. By separating the test and analysis system, both systems can be used productively and efficiently at the same time.
The Automotive Ethernet Tester consists of a 19-inch track with control and analysis software. A PC control unit controls the test system. Depending on the implementation, the test platform can contain up to 15 Ethernet ports (100BASE-T1, 1000BASE-T1), each of which can simulate and evaluate specific test scenarios. The test platform provides a display and PPS output for precise evaluation of the gPTP synchronization as well as a display for the port status. It also controls the power supply for the DUT.
