纲要：

SWC属于AUTOSAR的Component文件夹下，而Composition属于Composition文件夹下。

 

目录

1. Create Software Composition

2.  Add SWC into Composition

3. Create AssemblyConnector between SWCs

---

1. Create Software Composition

Right click on the project, then select "Create Composition", which will create "05_WiperControl_Composition.arxml" file and save this Composition information.

 

 

2.  Add SWC into Composition

 Right click on the "WiperControl_Composition" to open "Composition Editor", then select the SWC component type you want to add into the Composition.[1][2]

 

 

3. Create AssemblyConnector between SWCs

Select the port under "Source Component" and "Target Component", then click Connect button. [3][4]

注：

[1] "CPT" means Component Prototype

[2] 只能在之前已经创建的component库里面选。这就意味着，对一个AUTOSAR project，先去展开Component文件夹（或者去看看定义component的arxml文件）看看有哪些SWC类型，就可以大概了解这个project在做什么 

[3]该Composition下所有的SWC ports都会在这里显示出来，但在这里只需要把属于ECU内部通讯的SWC的port之间用AssemblyConnector把它们相互连起来（intra-ECU communication）

[4]剩下没连起来的就是属于需要与该ECU外部通讯的port接口，会在之后的SystemExtract阶段通过SystemDataMapping和ComSignal连起来，最终实现和外部的CAN/LIN/Ethenet总线通讯（inter-ECU communication）
