模型引用

将模型作为模块重用于其他模型

模型引用是对使用 Model 模块的另一个模型的引用。这些引用会创建模型层次结构。每个引用模型都有一个定义的接口,该接口指定其输入和输出的属性。定义的接口使得引用模型的行为独立于它在模型层次结构中的上下文。模型引用非常适合代码重用、单元测试、并行编译和大型组件。它们还可以减少文件争用和合并问题。

要确定引用模型是否满足您的建模需求,请参阅基于组件的建模规范

要了解模型引用层次结构的代码生成,请参阅引用模型 (Simulink Coder)

要创建受保护模型,请参阅模型保护 (Simulink Coder)

要对模型引用层次结构执行 SIL/PIL 测试,请参阅SIL 和 PIL 仿真 (Embedded Coder)
