Software-in-the-Loop Simulation
A software-in-the-loop (SIL) simulation compiles generated source code and executes the code as a separate process on your host computer. By comparing normal and SIL simulation results, you can test the numerical equivalence of your model and the generated code. During a SIL simulation, you can collect code coverage and execution-time metrics for the generated code.

Topics
- SIL and PIL Simulations
An overview of software-in-the-loop (SIL) and processor-in-the-loop simulations (PIL).
- Choose a SIL or PIL Approach
Test code generated from top models, referenced models, or subsystems.
- Configure and Run SIL Simulation
Set up and run top-model SIL, Model block SIL, and SIL block simulations.
- Unit Test Subsystem Code with SIL/PIL Manager
Perform unit testing on atomic subsystem by using SIL/PIL Manager.
- SIL/PIL Manager Verification Workflow
A simplified workflow for verifying generated code.
- Simulation Mode Override Behavior in Model Reference Hierarchy
How the simulation mode of the top model or parent model determines the simulation behavior of a model hierarchy.
- SIL and PIL Limitations
Modeling and code generation features that are not supported or partially supported by SIL and PIL simulations.
Troubleshooting
Debug Generated Code During SIL or PIL Simulation
Use a debugger to understand the behavior of generated code.
View SIL and PIL Files in Code Generation Report
Produce a code generation report and static code metrics that cover SIL and PIL files.
Numerical Consistency of Model and Generated Code Simulation Results
Determine whether model and generated code simulation results are numerically consistent. Investigate discrepancies.
