Model Publishing

R2026b
Publish a model to lock down simulation and code generation artifacts
Since R2026b

To speed up simulation and code generation for referenced models, you can create published models. These ready-to-run versions of Simulink® models contain build artifacts that Simulink unpacks and uses as needed. Simulink skips rebuild checks for published models, reducing model compilation and build overhead.

With published models, you can:

  • Lock down branches of a model hierarchy, preventing changes and rebuilds.

  • Reuse up-to-date build artifacts from Simulink cache files instead of regenerating them during publishing.

  • Share one published model that supports multiple platforms, compilers, releases, and code generation configurations.

  • Include supplemental files, such as instructions, test results, and code coverage reports.

  • Rename published models and create multiple published models from the same source model.

  • Log signals that you configure for logging before publishing.

  • Tune parameters.

  • Unpack the original data sources, such as data dictionaries.

  • Specify an alternate value source for external parameters.

To get started with published models, see Publish Models to Speed Up Simulation and Code Generation.
