Model/Software In the Loop Simulations
Accelerating Control System Development Through Virtual Validation
From Algorithms to Production-Ready Software
Modern vehicles rely heavily on sophisticated control algorithms to manage powertrain systems, vehicle dynamics, safety functions, electrification, and autonomous features. Developing these systems efficiently requires early validation, rapid iteration, and robust testing long before hardware becomes available.
Model-in-the-Loop (MIL) and Software-in-the-Loop (SIL) simulations provide a virtual development environment where control strategies and embedded software can be designed, tested, optimized, and validated throughout the development lifecycle.
Our simulation-driven workflow helps organizations reduce development time, improve software quality, and achieve faster deployment of reliable control systems.
What is Model-in-the-Loop (MIL) Simulation?
Model-in-the-Loop (MIL) is the earliest stage of control system validation, where both the plant model (vehicle, powertrain, or system) and the controller are represented as mathematical models within a simulation environment.
In MIL simulation, engineers can:
- Develop control algorithms rapidly
- Validate control logic before software implementation
- Evaluate system behaviour under various operating conditions
- Optimize controller parameters
- Perform fault and edge-case testing safely
What is Software-in-the-Loop (SIL) Simulation?
Software-in-the-Loop (SIL) is the next stage of virtual validation, where the actual production or auto-generated embedded software is executed against a simulated plant model.
SIL simulation allows engineers to:
- Verify software implementation accuracy
- Validate generated C/C++ code
- Compare software behavior with MIL results
- Identify integration issues early
- Measure execution performance and robustness
