Model Preparation for Real-Time Simulation

R2026b

Predefined and custom I/O driver blocks, code generation parameters, real-time kernel

A library of I/O driver blocks provides connections between physical I/O devices and real-time models. To observe how Simulink^® models respond to real-world behavior, use the Simulink Desktop Real-Time™ block library to create a real-time application from a Simulink model. Set the model configuration parameters to values consistent with real-time execution. The real-time application runs on your computer with the Simulink Desktop Real-Time kernel. See Prepare for Real-Time Execution.
