Startup from top Simulink model

Hello!

I would like to know if there is a setting somewhere in the Simulink options or a work around for the situation that whenever I start Simulink and open the a project/ model, I would like it to start from the top model instead of some random referenced model or a sub-system that I had been working on the last time before I logged off the computer or closed the Matlab program.

First of all, the model opens up wherever your view was (both location and zoom level) when you last saved it. A good best practice is to navigate up to the top before saving your model.

That aside, there is an "automagical" workaround. There are 2 commands you need to know for this, and you can use the documentation to look up more about this.

• open_system : Essentially, the command-line equivalent to open a Simulink model or subsystem.
• bdroot : This command gives you the top-level system name for the currently active model window.

So, if you are anywhere within a model, you can navigate to its top level by saying:

>> open_system(bdroot)

You can then put this in the PostLoadFcn callback of the model, as shown in this screenshot:
