How to reduce start time of my simulink model

I want to reduce the time to start the simulink model. I found the compilation is taking more time (5 minutes) before starting the model. I am using some reference models in my top model.

So I plan to precompile the model and start from precombiled state when required.

I used below steps to precompile and I think it working

myModel([], [], [], 'compile')

myModel([], [], [], 'term')

But when I start model, again the compilation happens and same time is elapsed Can someone help to start the model from precombiled state.

Hi DD,

It looks like you're on the right track with precompiling your model. To start the model from the precompiled state, you need to use the `sim` command with the `'internal'` option. Here are the steps you can try:

1. Load the precompiled model by running the `myModel([], [], [], 'load')` command. This loads the precompiled binary file.

2. Run the `sim` command with the `'internal'` option to start the simulation. For example: `sim('myModel', 'internal')`. This starts the simulation from the precompiled state and should skip the compilation step.

Note that the command `'myModel([], [], [], 'term')'` you mentioned is not required for precompiling the model. It is used to terminate a simulation that is running.

Also, keep in mind that if you make any changes to the model or dependencies after precompiling, you will need to re-precompile the model for the changes to take effect.

If you continue to experience issues with the model compiling time, you may also want to consider making optimizations to your model or looking into methods for efficient model execution.k

Hope it helps!
