基于模型的嵌入式软件开发和质量保证介绍
内部培训
This training class provides a practical overview of developing and safeguarding embedded software on the basis of Simulink and code generators like Embedded Coder and TargetLink within the framework of serial projects. The training class takes participants through all process steps from designing and creating the simulation model in Simulink and Stateflow to generating production code.
Model quality assurance consists of verifying the model and software architecture, safeguarding the modeling guidelines, as well as checking for functional compliance with requirements in the model test. The efficient requirements based test specification is implemented for the created models and applied in MiL and SiL tests. Functional accuracy is verified by the evaluation of regression and back-to-back tests. You will learn how to follow all the steps in practical exercises using the MES Test Manager (MTest), the MES Model Examiner (MXAM), and the MES Quality Commander (MQC).
目标受众
This training class is for novices to model-based development of embedded software based on Simulink and Embedded Coder or TargetLink, including developers, testers, quality managers, project managers, and team leaders. Only basic modeling knowledge of Simulink and Stateflow is required.
