Hello,

I want to find duplicate sub systems in model. For example, I have sub system like shown image.

As we can see, duplicate sub system2 is created even though there is no IO changes.

so my interest is to find these kind issues in model using MATLAB commands.

Here is my code as of now:

subSystemHandles = find_system(bdroot,'BlockType','SubSystem');
for k=1 : length(subSystemHandles)
    allSubSystem = get_param(subSystemHandles(k),'Name');
    eachSubSystem = get(gcbh);
    inPortHandles = eachSubSystem.LineHandles.Inport;
    inPortNames=get(inPortHandles,'Name');
      outPortHandles = eachSubSystem.LineHandles.Outport;
      outPortNames=get(outPortHandles,'Name');
end

Here I am trying to read Names of Inport and OutPort using get_param but I am not getting names.

Please, Could some one help me on this?

From what I understand, if a particular SubSystem block has the following blocks within - it would be flagged as redundant.

1. Matching ports and port-blocks within.

2. A single SubSystem block.

3. No other blocks.

Would you agree that this is the problem you're trying to solve?

This below code should work for reasonably simple subsystems. I haven't tried for any complex ones - like with triggered input.

mdl = 'MySubSys';
load_system('MySubSys')
allBlks = find_system(mdl, 'Type', 'block', 'BlockType', 'SubSystem');
flags = zeros(1,length(allBlks));
for k=1:length(allBlks)
    currentPorts = get_param(allBlks{k}, 'Ports');
      insideBlks = find_system(allBlks{k}, 'SearchDepth', 1, 'Type', 'block');
      insideBlkType = get_param(insideBlks, 'BlockType');
      insideIPnum = length(find(strcmp(insideBlkType, 'Inport')));
      insideOPnum = length(find(strcmp(insideBlkType, 'Outport')));
      insideSSNum = length(find(strcmp(insideBlkType, 'SubSystem')));
      insideRestNum = length(insideBlkType)- insideIPnum - insideOPnum - insideSSNum;
      if insideIPnum==currentPorts(1) && insideOPnum==currentPorts(2) ...
                         && insideSSNum==2 && insideRestNum==0
                     flags(k)=1;
      end   
end
ids = find(flags(:)==1);
redundantSubSys = allBlks(ids);
