变体内联组件

在单层中实现结构性变化

使用内联变体模块，您可以在单个模型中表示一个系统的所有设计备选方案。每个设计选择项都作为单个层中的一个变体选择项纳入模型中。这种模型有固定的通用结构和一组有限的可变组件，这些组件根据具体变体控制项而被激活或反激活。您可以自动或手动激活组件。

例如，假设您要仿真一个模型，以通过使用不同雨量传感器来控制汽车挡风玻璃雨刷的速度。您可以提供雨量传感器模型作为 Variant Source 模块的输入，然后根据您选择的变体控制项在传感器之间切换。有关详细信息，请参阅Introduction to Variant Controls。

您为内联变体模块生成的代码可以包含一个系统的所有变体选择项。您可以在代码编译前或在模型启动时在选择项之间切换，如Activate Variant During Different Stages of Simulation and Code Generation Workflow中所述。有关使用内联变体模块生成代码的信息，请参阅Represent Subsystem and Variant Models in Generated Code (Embedded Coder)。
