基于事件的调度

异步事件处理、采样率转移、计时器、事件数据

模型中可以包含模块，以生成处理异步事件的代码，例如以下异步事件：

要进行仿真，您可以将异步事件数据导入到函数调用子系统中。

模块

Asynchronous Task Specification	指定由异步中断触发的引用模型表示的异步任务的优先级
Async Interrupt	生成执行下游子系统或 Task Sync 模块的 Versa Module Eurocard (VME) 中断服务例程 (ISR)
Task Sync	Run code of downstream function-call subsystem or Stateflow chart by spawning an example RTOS (VxWorks) task

异步事件
一种设计模型，支持模块的执行以响应与系统的周期计时源异步发生的事件。
Rate Transitions and Asynchronous Blocks
Use Rate Transition blocks to handle data transfers to and from asynchronous blocks.
Generate Interrupt Service Routines
Generate an interrupt service routine (ISR) that is associated with a specific VME interrupt level.
Timers in Asynchronous Tasks
Maintain absolute and elapsed timing data for blocks that execute in the context of an asynchronous task with the code generator.
Create a Customized Asynchronous Library
Create custom blocks that support handling of asynchronous events with vxlib1 library blocks as templates.
Import Asynchronous Event Data for Simulation
Import asynchronous event data into a function-call subsystem.
Asynchronous Support Limitations
Limitations of asynchronous event support.
