Refer to Simulation time in Simulink

Morning!

I have created a model which gives the output after a certain part of simlation time has elapsed. i.e. Consider the following example:

<Subsystem_1> --> If Simulation time == x, then provide output of Subsystem 1 to --> <Subsystem_2>.

So, Subsystem_1 runs with respect to simulation time and the Subsystem_2 only gets the output from Subsystem_1 once Simulation time has elpased x-units.

Now, i have done the same using If-Else Block(along with the action susbsystem).

Question: Hints or Command ,which does the same without explicitly specifying with a If-Else block?

Subsystem_1 = Pulse Generator + Counter
Subsystem_2 = Matlab Embedded Function + Simout

So, just to regress: A command which i can include in the Embedded Function.

Thanks for your consideration!

Can you show a pic of the block diagram? I would avoid using a MATLAB Fcn if at all possible. You can run into code gen issues later. It sounds like you may want an enabled subsystem...

Ryan G: Thanks for your answer and sorry for the super late reply. Actually, i cant upload a pic coz i cant access any Image-Sharing websites. But i humor me :

   -Block 1-         -Block 2-     -Block3-                -Block4-

Pulse Generator -> Counter -> Embedded matlab FCN -> Display

So my intention is: If the simulation time is set to 51,then Wait until counter has finished counting untill say Simulation Time-50, and in the next 1 unit of simulation time to calculate the FCN. I have already checked with -tic,toc- the time is enough. So, i hope this whole setup give you a better idea! Thanks again for your patience!

I guess the difference between simulation time and clock time can be a bit confusing to discuss via internet. If you mean sim time, you can use a clock or digital clock block to do this. If you mean clock time, tic toc may be valid, but I don't think you should use clock time at all.

What you can do is put -Block3- inside of an enabled subsystem. Connect the clock block (this is in the Simulink library) to a comparison, 50 in this example. Connect the output of that to the enabled port of the enabled subsystem. That should do it.
