Enable SIL Debugging With Visual Studio 2022

I want to debug an entire simulink model running in a C++ compiled application. This article appears to address it:

https://www.mathworks.com/help/ecoder/ug/debug-code-during-sil-simulations.html

However, no runtime functions are found. I have installed the r2025b runtime matching my Matlab, verified that the runtime is in the path, restarted the computer.

I found this on that web page:

To enable your debugger for a SIL simulation, perform one of these actions:

• On the SIL/PIL tab, in the Settings gallery, under SIL/PIL Settings, click Debugging.
• In the Configuration Parameters dialog box, select the Enable source-level debugging for SIL or PIL check box.

Where is the SIL/PIL tab in the Settings gallery, or conversely the Configuration Parameters setting?

Hello,

The SIL/PIL tab is available in the Simulink Toolstrip when you select a block or model that supports SIL or PIL.

Steps to Access the SIL/PIL Tab:

1. Open your Simulink model.
2. Select the block (often a Model block or Subsystem) that you want to run in SIL or PIL mode.
3. Once selected, you should see a new tab appear in the Simulink Toolstrip labeled SIL/PIL.

If you don't see it, make sure your block is eligible for SIL/PIL (typically, Model blocks configured for code generation).

SIL/PIL mode is available for blocks/models that are set up for code generation (i.e., Embedded Coder is required).

After enabling debugging, regenerate code and rebuild the SIL target.

Configure and Run PIL Simulation - MATLAB & Simulink

Hope this helps.

Hi Isha,

Thank you for replying. The model I have is large, developed by others, so I'm feeling my way at this point.

I have Simulink Coder. This entire project is coded into C, everything is set up for code generation. Neither selecting the dot-slx component in the model explorer nor selecting a block within a project causes the SIL/PIL tab to appear in the Simulink toolstrip. I was able to find it starting from the apps tab.

After re-reading SIL/HIL documentation, SIL requires Simulink to start the compiled model in a new process to enable debugging in Matlab/Simulink. So this won't work for the use case I was envisioning.

Best regards,

Bill
