It supports creating non-periodic threads—such as event-driven communications or idle-time workers—that run asynchronously to the main control loop. Key Block Categories
Quarc is not a standalone software; it lives inside the Simulink Library Browser.
Under the hood, Quarc uses its own code generator. In benchmarks, it is generally faster and generates more compact code than the standard Simulink Coder for the specific targets it supports. It handles the real-time operating system (RTOS) scheduling (usually on VxWorks or real-time Linux patches) automatically. quarc library simulink
The end result was a highly sophisticated autonomous vehicle that performed flawlessly in a variety of test scenarios. Dr. Hernandez's team was thrilled with the results and credited QUARC with helping them overcome some of the toughest challenges in control systems development.
The library includes a suite of blocks for TCP/IP, UDP, Serial, SPI, I2C, and shared memory, all manageable via a unified Universal Resource Identifier (URI) system. In benchmarks, it is generally faster and generates
One of the hidden gems of the Quarc library is its Stream API. It allows for Inter-Process Communication (IPC) and networking.
Dr. Maria Hernandez, a control systems engineer at a leading research institution, had been working on a complex project to develop an advanced autonomous vehicle. Her team had designed a sophisticated control system, but they were struggling to test and validate their design. That's when they discovered the QUARC library in Simulink. accelerating their development process.
The Quarc Library (often stylized as QUARC) is a premium add-on for Simulink designed by Quanser to facilitate rapid controls prototyping, hardware-in-the-loop (HIL) simulation, and deployment on real-time systems. It acts as the middleware that translates Simulink block diagrams into executable code for embedded targets (like the Qube, QCar, or generic Linux/VxWorks targets) without the user needing to write low-level C/C++ code.
In summary, Quarc transforms Simulink from a simulation tool into a real-time control powerhouse, justifying its cost through the sheer amount of development time it saves.
The simulations revealed some unexpected issues with their control system, which the team was able to address and refine. Thanks to QUARC, they were able to iterate rapidly and make adjustments on the fly, accelerating their development process.
