Limitations with Multicore Programming in Simulink
The following limitations apply when partitioning a model for concurrent execution.
Configure the model to use the fixed-step solver.
Do not use the following modes of simulation for models in the concurrent execution environment:
External mode for Mac desktop targets.
Logging to MAT-files (MAT-file logging check box selected). However, you can use the To Workspace and To File blocks.
If you are simulating your model using Rapid Accelerator mode, the top-level model cannot contain a root level Inport block that outputs function calls.
In the Configuration Parameters dialog box, set the Diagnostics > Sample Time > Multitask conditionally executed subsystem and Diagnostics > Data Validity > Multitask data store parameters to
If you want to use explicit partitioning, at the root level of your model, the model must consist entirely of
Models that are referenced using Model blocks
MATLAB® System blocks
MATLAB Function blocks
Rate Transition blocks
Virtual connectivity blocks
The following are valid virtual connectivity blocks:
