I have two simulink models (say X and Y), I should first run X, and after few seconds(lets say 10sec), I need to run Y when X is already in execution phase. And this has to be done from matlab command line. I have tried using set_param(), but unable to do the simulations as expected.

Can someone help with that?

  • Why do they need to be run in this way? Is delay important? – Wolfie Sep 18 '17 at 12:48
  • You can certainly use `set_param('modelname','SimulationCommand','start')` from the command line to start both models. You need to explain what you mean by `unable to do the simulations as expected`. – Phil Goddard Sep 18 '17 at 16:23
  • Thanks for that Phil, I have tried it too, I would like to start X model first, after 20sec of X model is started, I wish to run Y model. Will this case work with above said set_param? – Test Engineer Sep 19 '17 at 04:54
  • Hey Wolfie, yes delay is important – Test Engineer Sep 19 '17 at 04:58

One solution could be to include both models as part of a supermodel using model blocks and put the model block that is to be delayed inside an enabled subsystem that is switched on after 10 seconds (using a delay mechanism for the enable).

Depending on what you want to do, you could also execute separate matlab processes and implement some sort of shared trigger (file, socket communication, etc.), but then that's kind of outside the realm of simulink, and you will get asynchronism.
