Running subsystems individually in Simulink

Good day all, I am currently having trouble with my Simulink model. There are 2 subsystems A and B. I would like to make subsystem A run first then using the data produced, run subsystem B. Is there a function of Simulink block i could use to execute this?

I have tried using trigger and enable with a step input of 10sec before subsystem B but it didn't work. I have tried a store memory but it didn't work too. A Variant subsystem is considered but as the input to both subsystems A and B are different, i assume it would not work as well.

I would appreciate the help and support i can get from you guys! Thank you very much!

Hi SY,

If you want A to run first AND you want data from A to run into B, then you likely will only need to connect A->B. Another possibility is the use of function call subsystems for A and B and some sort of scheduler (Stateflow chart or MATLAB function block).

Perhaps you could supply a simplified example model to demonstrate the 2 subsystems and a brief description of how you expect the model to behave.

Hi Zack. Thank you for the reply. I have attached a Simulink model in the link attached below. Basically, Subsystem A is a PV configuration which has to run first to obtain my V-P graph. Then subsystem B consisting of a MATLAB function and converter would be used to process the data from Subsystem A(PV configuration). I hope this explanation of my problem would be clearer.

I would use and atomic subsystem(https://www.mathworks.com/help/simulink/slref/subsystem.html) unless you want to buffer and collect all data from A and pass it into B. The atomic subsystem will set the execution order of A to run first and then only once process will it pass data to B.

HI SY could you solve ypur problem?
