Shulou(Shulou.com)06/03 Report--

The OPEN Alliance officially released the TC8 vehicle Ethernet ECU test specification version 3.0 on May 8th. Compared with version 2.0, the version 3.0 specification removes some test cases that are not suitable for the vehicle environment, and updates the description problems of some use cases in version 2.0. In order to reliably solve the conformance testing problem of vehicle Ethernet Layer 3-7, Jingwei Hengrun independently developed an automated test suite AETP that covers all test cases of TC8 v3.0 Layer 3-7.

Main update points of TC8 v3.0 test specification

Before you learn about AETP products, let's take a look at the major updates to TC8 v3.0. The test specification is divided into three parts, which form three specifications of TC8 v3.0 Layer 1 Magi layer 2 Magi layer 3-7. In summary, the TC8 v3.0 test specification is more mature, more in line with the testing requirements of the vehicle environment, and provides a clearer test guidance for the vehicle Ethernet ECU level testing.

AETP- TC8 v3.0 compliant vehicle Ethernet Test tool

AETP (Automotive Ethernet Test Package) belongs to the Jingwei Hengrun INTEWORK product line, which is an on-board Ethernet test suite based on the test software INTEWORK-TAE. The AETP test script for the TC8 v2.0 test specification was developed in mid-2019, and more than 50 vehicle Ethernet test samples have been verified so far. AETP software interface Jingwei Hengrun, as a partner of Ruetz, a member of the OPEN Alliance and co-chair of the TC8 group, continuously followed the progress of the update during the discussion of the TC8 v3.0 specification. We started the AETP adaptation update work since the release of the internal member version of TC8 v3.0, and made a comparative analysis with the TC8 v2.0 version after the release of TC8 v3.0 official version, adjusted the test script and completed the test verification, and completed the test suite covering TC8 v3.0 specification as soon as possible. AETP features complete test cases covering AETP currently covers all test cases of TC8 v3.0 Layer layer 3-7 TCP/IP and SOME/IP, meeting the relevant needs of the market. Especially in SOME/IP ETS testing, due to the unclear definition of ETS service interface parameters in TC8 v2.0 specification, many difficulties will be encountered in the implementation of ETS testing. With years of experience in vehicle Ethernet development and testing, Jingwei Hengrun summarized the definition of ETS service interface that meets the testing requirements in TC8 v2.0, which is highly consistent with the definition of ETS in TC8 v3.0 specification. This also lays the foundation for the rapid launch of AETP SOME/IP ETS test scripts. In addition, other TC8 v3.0 test content (e.g. IOP test package, etc.) and part of the vehicle Ethernet application layer test content (e.g. DoIP test package) have also been released, and more content will be available to you in the intensive development process. AETP Roadmap convenient operation experience TC8 test specification defines a large number of test input parameters, which need to be fully understood before their specific meaning and configuration can be clearly defined. In order to reduce the threshold of test execution, Jingwei Hengrun test software development engineers optimize the configuration of test parameters based on a lot of testing experience to help test newcomers get started quickly. After the user completes the parameter configuration, the user can create a batch run test case group. By directly selecting and running individual test cases or test case groups, the corresponding tests can be completed automatically and test reports can be generated. The whole process does not require steps such as reloading parameters, recompiling files, or rebuilding executable files, which greatly saves testing time. Rich test results show that test reports can be generated in a variety of formats according to requirements. The test report uploads the expected results of each step and the actual test results in detail. If a test case sample test fails, the test report can clearly determine the requirements of the test case and the reason for the failure, and help testers to quickly identify the problem points. AETP test report friendly secondary development environment AETP test suite key functions provide a call interface, you can use the existing various types of programming modules in INTEWORK-TAE to quickly complete the construction of test cases and achieve the secondary development of test cases. The lightweight test environment AETP's layer 3-7 test does not require specific hardware to be used together, which avoids the problem of inconvenient movement and high price of external test equipment. If you have a need for TC8 on-board Ethernet testing, please leave a message or contact Jingwei Hengrun sales to obtain the AETP trial version. TC8 ETS integrated benefits: Wechat official account to reply or leave a message under this article "AETP" and your name, organization, phone, email, we will provide you with ETS service interface definition in accordance with TC8 v3.0 specification. The ETS service interface definition is the integrated input document of the TC8 SOME/IP ETS test, which defines the interface, parameter type and length of the ETS service in detail.
