Breaking the links of ONLY the selected variants in Simulink

Hello

I have a simulink model with a lot of subsystems that contains Variants subsystems in different locations in the model.

I want o break the links of only the Variants chosen in the simulation and save the model to share without sharing the whole libraries with it.

Breaking all the links using : save_system('Mymodel.slx','export.mdl','BreakALLLinks',true)

Takes a lot of time and doesnt work if it cant find a link to a library even if its not used

I was thinking about looking for scanning the model and get the variants that are chosen and then broke only these variants but i cant find the right commands.

Could you please help me with this issue ?

Thank you

Hi Ayyoub,

The following commands might help:

1. To find variant blocks that are active in simulation after model compilation:

set_param(model,'SimulationCommand','update');
blks = find_system(model,'MatchFilter',@Simulink.match.activeVariants)

You can find an example and more information in the documentation here:

https://www.mathworks.com/help/simulink/slref/find_system.html#mw_45152364-99d4-4a25-87fb-0d34bf1d66a1

2. To break a link to the library

set_param(blk,'LinkStatus','none')

The "LinkStatus" parameter provides information about the connection between a referenced block in a model and its corresponding block in a library.

For more information, refer to the documentation here:

I hope this helps!
