Study On AUTOSAR Conformance Testing By Using TTCN-3

Along with the development of automotive electronics, the number of ECUsincreases, the software structure is more complex, all these make it is difficult todevelop automotive electronics software. At the same time, all the softwaredevelopment standards of vendors are not unified, so the price of migrating thesoftware solution to the different environments in automotive electronic systems isvery high. It’s time to unify industry standardization within the softwares to improvethe software reusability, reliability and stability, and enhance the configurable of theautomotive system software, and reduce the complexity of the software structure.AUTOSAR standard defines a set of automotive software architecture and thedevelopment methods, that can improve the reusability of software, reduce the costs ofsoftware development.Currently, AUTOSAR standard has been widely applied in the world, but differentvendors have different understanding about AUTOSAR standard, so there will bedifferences in the realization. How to ensure the accuracy and security, which is animportant content of AUTOSAR conformance test. AUTOSAR conformance testcontain static test and dynamic test, the static test check the configuration parameters,and the dynamic test check the software module behavior of automotive electronic.The paper study on AUTOSAR conformance test, the main tasks as below:Analyses the AUTOSAR related technologies, which covers the AUTOSARarchitecture, software component and current research situation. The method ofdynamic testing in AUOTSAR conformance test has been discussed. And introduceinto the TTCN-3test architecture, present TTCN-3basic theory and current researchsituation.This paper proposes a method of the conversion from the data type of AUTOSARto the data type of TTCN-3, and the data conversion function has been completed onthis basis, using the data conversion tool, testers don’t need to focus on conversionprocess, that can improve the efficiency of the test.In this paper, research the adapter and codec under TTCN-3test framework,focuses on the method of encoding and decoding. Simple blinker system as the systemunder test, and prepares test suite use TTCN-3, the system under test has completed by simulation, achieve the conformance test by TTCN-3test framework.
