Hello,
I made a small script to do this.
So, basically if you have a 'Block_A' in your library and you want to change it.
You copy 'Block_A' and rename it to 'Block_B' and make any changes you want except modifying the parameters.
Now, you call this script as renameLibLinks('modelname','Block_A','Block_B'). This script will parse through the entire model hierarchy ( including any model references) and replace all links to Block_A with Block_B. Once this is complete you can then delete Block_A in your library.
function renameLibLinks(mdl,origLibBlockName,newLibBlockName)
% RENAMELIBLINKS(model, orignalLibraryBlockName, newLibraryBlockName)
% This function will parse through the model for all blocks which are
% linked to originalLibraryBlockName and replace their link with
% newLibraryBLockName
%
% eg. >> renameLibLinks(gcs,'Control/block_A','Coordinates/block_B')
%%Load Model
system = load_system(mdl);
origRefBlock = ['mbdriLib/',origLibBlockName,'.*'];
newRefBlock = ['mbdriLib/',newLibBlockName];
blocks = find_system(system,'FollowLinks','on',...
'LookUnderMasks','on',...
'RegExp','on',...
'LinkStatus','resolved',...
'ReferenceBlock',origRefBlock);
% Unlock Lib Link
set_param(mdl, 'LockLinksToLibrary', 'off')
%%Find lib and rename
for i=1:numel(blocks)
set_param(blocks(i),'ReferenceBlock',newRefBlock);
end
end
Hope this helps.
Cheers, Gautham
