Environment Controller
Create branches of block diagram that apply only to simulation or only to code generation
- Library:
Simulink / Signal Routing
Description
The Environment Controller block outputs the signal at its Sim port only if the model that contains it is being simulated. It outputs the signal at its Coder port only if code is being generated from the model. This option enables you to create branches of a block diagram that apply only to simulation or code generation. This table describes various scenarios where either the Sim or Coder port applies.
| Scenario | Output |
|---|---|
| Normal mode simulation | Sim |
| Accelerator mode simulation | Sim |
| Rapid accelerator mode simulation | Sim |
| Simulation of a referenced model in normal or accelerator modes | Sim |
| Simulation of a referenced model in processor-in-the-loop (PIL) mode | Coder (uses the same code generated for a referenced model) |
| External mode simulation | Coder |
| Standard code generation | Coder |
| Code generation of a referenced model | Coder |
Simulink® Coder™ software does not generate code for blocks connected to the Sim port if these conditions hold:
On the Code Generation > Optimization pane of the Configuration Parameters dialog box, you set Default parameter behavior to
Inlined.The blocks connected to the Sim port do not have external signals.
The Sim port input path does not contain an S-function or an Interpreted MATLAB Function block.
If you enable block reduction optimization, Simulink eliminates blocks in the branch connected to the Coder port when compiling the model for simulation. For more information, see Block reduction.
Note
Simulink Coder code generation eliminates the blocks connected to the Sim branch only if the Sim branch has the same signal dimensions as the Coder branch. Regardless of whether it eliminates the Sim branch, Simulink Coder uses the sample times on the Sim branch as well as the Coder branch to determine the fundamental sample time of the generated code and might, in some cases, generate sample-time handling code that applies only to sample times specified on the Sim branch.
