Simulink_Debug的使用

1. 搭建模型

2. 启动 Debug 调试器

2.1 点击运行

左栏Simulation Loop: simulate(TestDebugSimulink) 高亮显示
且ID = 0
右栏Outputs:输出：

%----------------------------------------------------------------%
[TM = 0                      ] simulate(TestDebugSimulink)
(sldebug @0): 

2.2 step into 一步步进行分析

2.3 第一次点击 stepinto

左栏Simulation Loop: initializationPhase 高亮显示
且ID = 1
右栏Outputs:输出：

%----------------------------------------------------------------%
[TM = 0                      ] initializationPhase
(sldebug @1): 

由此可以看出：

1. Outputs中输出的(sldebug @X):为左栏中的 ID号
2. initializationPhase应为左栏中的Method

因此，不断地点击StepInto,在Outputs中得到内容如下

2.4 不断点击 stepinto，得到Outputs中的全部内容如下

警告: The behavior of the Simulink Debugger has been modified in R2012b. See release notes for details.
警告: 'Signal storage reuse' is enabled for this model. Block I/O values displayed in the debugger may not be correct.
 In order to preserve block output signal values, consider disabling the 'Signal storage reuse' option in the 'All Parameters' tab of the Configuration Parameters dialog

警告: 'Block reduction optimization' is enabled for this model. Some non-virtual blocks may not execute due to optimization.
 To be able to execute all non-virtual blocks consider disabling the 'Block reduction optimization' option in the 'All Parameters' tab of the Configuration Parameters dialog

3. 总结分析

Simulink 仿真主要步骤：

1. 准备开始工作
2. 仿真过程
3. 重复仿真过程
