Quarc Library Simulink 【2026 Update】
Understanding the QUARC Targets Library for Simulink QUARC Real-Time Control Software is a powerful tool by that transforms
Live Parameter Tuning: Change gains, setpoints, or logic in the Simulink model while it is running on the hardware, and see the results instantly without stopping the process. quarc library simulink

✅ Hard Real-Time Performance: Achieve deterministic execution on Windows (real-time extension) or Linux (with PREEMPT_RT) – ideal for robotics, aerospace, and mechatronics. 1.2 Key Capabilities
Example: Controlling a DC Motor. You read an encoder using HIL Read Encoder, compute a PID control law in Simulink, and output a PWM signal via HIL Write PWM.
The "Code-Less" Workflow
The defining feature of Quarc is its abstraction of the deployment process. In a standard workflow, an engineer designs a controller, generates C code using Embedded Coder, writes hardware drivers, compiles the code, transfers the executable, and debugs. Quarc collapses this into a "Build" and "Run" button within the Simulink interface.
3. Real-Time Visualization and Interaction
One of the biggest challenges in hardware-in-the-loop (HIL) testing is debugging a system that is running faster than the human eye can track. Quarc solves this with advanced monitoring tools.
Typical Use Cases
- Automotive ECU development (control, diagnostics, fault management)
- Aerospace flight-control prototyping and production code
- Industrial automation controllers migrating from hand-written C to model-based workflows
- Projects requiring strong traceability and verification for certification
1.2 Key Capabilities
- Hardware-in-the-Loop (HIL): Connect sensors and actuators directly to your Simulink diagram.
- Real-Time Synchronization: Ensure that the loop executes at precisely defined sample rates (e.g., every 0.001s).
- Streaming & Logging: Monitor signals in real-time using Simulink’s Scope or log data to MAT-files without interruption.
- Remote Control: Deploy models to a dedicated real-time target machine and interact with them from a host PC.
