MATLAB: How to list the different variants of a block library in Simulink 7.5 (R2010a)

simulink

I have a Model block and would like to list all the model reference variants I have previously defined in the associated library.

Best Answer

The different variants of a block can be listed as follows:

% Replace BlockName with the actual block name
modrefblock = find_system(gcs, 'Name', 'BlockName'); 
% Variants is a cell array containing a structure
variants = get_param(modrefblock, 'Variants'); 
% Variantnames is a cell array with the names of all variants
variantnames = {variants{1}.ModelName};

The first command is retrieving the handle to the model block in the Simulink model. With the second command, all the variants of the model are returned as a cell array. If you only need to retrieve the names, you can consider extracting just the first field of the previously obtained structure.

All the fields of the structure can be listed with:

disp(variants{1})

MATLAB: Find Triggered subsystem in a simulink model

One potential method would be to generate a list of all the blocks in your Simulink model, and then find blocks which are of the type 'TriggerPort'. From there, you just need to determine the parent block of the 'TriggerPort' which gives you the Triggered Subsystems that you are looking for. You can accomplish all of these operations programmatically via the get_param and find_system functions.

Here is a quick little example script that performs the operations that I described above. The find and strcmp functions are used to determine which blocks are of the type 'TriggerPort' from the blockTypes cell list.

% Generate a cell list of all blocks in the current Simulink model
blockList = find_system(bdroot,'Type','block');
% Generate a list of the block types
blockTypes = get_param(blockList,'BlockType');
% Find all blocks with trigger ports (enabled subsystems)
indexTrigger = find(strcmp(blockTypes,'TriggerPort'));
% Interate through all found triggers and determine "parent" subsystem
for i = 1:numel(indexTrigger),
    triggeredSubs{i} = get_param(blockList{indexTrigger(i)},'Parent');
end

Hope this helps to get you started!

MATLAB: Is it possible to locate the blocks that are causing specific license checkout requirements for the model using the Model Manifest in Simulink 7.5 (R2010a)

This functionality is not directly provided in Simulink 7.5 (R2010a). As a possible workaround, you can use the property "ReferenceBlock" to perform an exhaustive query of the blocks in your model.

As an example,

blks=find_system('TS_example');
libchk{1}='simevents'; %name of library ;

libchk{2}='otherpossiblelibraryprefixeshere';
%note that libraries and their sub-structured components may 
% not have the same name so you must list all possible libraries
% in the libchk cell
blks=find_system('TS_example');
libchk{1}='simevents'; %name of library ;
libchk{2}='otherpossiblelibraryprefixeshere';
for ind = 1: length(blks)
      try
          ind;
          refblk=get_param(blks{ind},'ReferenceBlock');
          if strncmp(refblk,libchk{1},length(libchk{1}))
              disp(['Block found in referenced library  ',blks{ind}]);
          elseif strncmp(refblk,libchk{2},length(libchk{2}))
              disp(['Block found in referenced library  ',blks{ind}]);
          end
      catch EM
      end
end
 Block found in referenced library  TS_example/Entity Splitter
