设计、分析和测试系统架构与软件架构

对于系统工程，使用 System Composer™ 对表示和仿真您的系统的架构和组件行为进行建模。System Composer 中的工作流涉及将利益相关方的需求捕获到系统级需求中，然后使用它们通过行为模型来驱动您的架构设计。使用 System Composer，您可以：

用组件、端口和连接器组成架构模型。
扩展建模语言以获取元数据，并使用原型构建架构元素的风格。
定义端口上的数据、物理或客户端-服务器接口，并使用连接器来描述组件交互。
捕获组件接口，包括端口接口和参数。
通过使用基于元素或属性值的过滤器来生成架构视图。
在序列图中表示您的系统，以将系统行为描述为一系列交互。
使用分配在功能、逻辑和物理架构之间建立直接关系。
执行分析和权衡研究，以优化您的架构设计。

通过添加 Requirements Toolbox™，您可以定义功能和设计需求，并将它们链接到 System Composer 组件和端口。将 Requirements Toolbox 与 Simulink^® Test™ 结合使用，通过创建测试用例的链接来自动验证需求。Simulink、Stateflow^® 和 Simscape™ 也可以描述架构模型中的组件行为。

您可以使用所有这些工具，在程序的整个生命周期中创建和管理需求以及功能、逻辑和物理架构。
