Simulink® Desktop Real-Time™ provides a real-time kernel for executing Simulink models on a Windows® or Mac laptop or desktop. It includes library blocks that connect to a range of IO devices. You can create and tune a real-time system for rapid prototyping or hardware-in-the-loop simulation with your computer.Simulink Desktop Real-Time supports real-time performance with lower sample rate for normal mode simulation in Simulink, and supports higher sample rates for external mode simulation in Simulink with Simulink Coder™.
