Input models for the AUTOSAR Gateway Sample Clauses

Input models for the AUTOSAR Gateway. As specified before, AUTOSAR Gateway servers to generate AUTOSAR model (UML model profiled with AUTOSAR concepts) and out of the last, AUTOSAR Gateway can generate arxml file. Therefore this subsection will be divided accordingly to this two-step generation process. 2.1.2.1 EAST-ADL2 to AUTOSAR model Generation of AUTOSAR model consists of three phases. These are generation of the Application View, the Topology View and the Mapping View. The first one contains specification of the software components types and their prototypes. Topology View relates to the hardware topology. Mapping View encompasses the definition of a mapping, i.e. software components to ECUs allocation. Proper and complete generation of each view depends on the information included in the EAST-ADL2 model. Let us consider the EAST-ADL2 model as composed out of three packages representing the functional architecture (FDA – Functional Design Architecture), hardware topology (HDA – Hardware Design Architecture) and Allocation, i.e. mapping of functional entities onto the hardware topology. Figure 1 represents general dependencies of the generation results from the information included in the EAST-ADL2 model. Namely, in order to generate complete and correct Application View it is necessary to provide FDA, HDA and Allocation. This is a consequence of the approach used to generate software architecture. Namely, all the atomic functions of the same composite function and allocated on the same ECU are transferred to one atomic software component type. The last contains the runnable entities, where each runnable entity is generated from one atomic function. In general the way in which software architecture is generated, i.e. software component types, their prototypes and runnable entities, is influenced by the compositional structure of the functional model (FDA) but also the way in which atomic functions are allocated on the nodes. Therefore all three models, i.e. FDA, HDA and Allocation are necessary to generate Application View model. Allocation View Topology View Application View Allocation Figure 1. Dependencies in the Generation of the AUTOSAR Model from the EAST-ADL2 Model 2.1.2.2 AUTOSAR model to arxml Generation of the arxml file is relatively simpler than the generation of AUTOSAR model from EAST-ADL2. This is a consequence of using one-to-one transformation, i.e. each entity from the AUTOSAR model has one, corresponding entity in the arxml file. This was not the case for the AUTOSAR mo...
