Configure Simulink Real-Time Models

Prepare an existing Simulink model to build as a Simulink Real-Time application — configuring it consistently with the selected target platform, solver requirements, and Simulink Real-Time build options.

Release compatibility: Designed and validated for MATLAB R2026a and later. Earlier releases differ in APIs, system target files, and workflows — use that release's product documentation instead.

When to Use

• Setting up a Simulink model for Simulink Real-Time, or preparing it before slbuild
• Selecting or correcting the system target file (STF/TLC), including models on grt.tlc or ert.tlc
• Reviewing or setting fixed-step solver options for real-time execution while preserving the model's intended dynamics and sample-time behavior
• Configuring model parameters for a selected Speedgoat target computer or compatible Linux device — toolchain details, or Simulink Real-Time options (log level, polling mode, max file log runs, GCC -ffast-math)
• Handling errors about incompatible target platforms or missing target platform selection
• Running Upgrade Advisor for an older Simulink Real-Time model
