Hello,

is there a quick way to have a bus inherit the signalnames form the output ports of a subsystem?

I am using vehicle network toolbox. CAN unpack is handy but gives a lot of signals. Now I am manually naming the signals when I create a new bus at CAN_unpack out. Any quick magic spell to speed this up?

Thanks

Found a solution:

Use a blank simulink model. Copy/Past your "CAN-unpack" subsystem into it. Run the script.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% please mark the "CAN-unpack" before execution !
file=get_param(gcb,'CANdbFile');         % your CAN DBC file here!
db=canDatabase(file);
msg_name=get_param(gcb,'MsgName');
Msg=messageInfo(db,msg_name);
porthandles = get(gcbh,'PortHandles');
%%%% iterate thru all outports of the selected block and draw a signal line
for i = 1: size(porthandles.Outport,2)
    %% draw a line at each Out-Port
    pos = get(porthandles.Outport(i), 'Position');
    linepos = [pos(1)+200 pos(2)-5 pos(1)+200+10 pos(2)+5];
    temp_block = add_block('simulink/Commonly Used Blocks/Terminator',[gcs '/Term_' int2str(i)],'Position', linepos);
    
    h1 = get_param(temp_block,'PortHandles'); 
    add_line(gcs,porthandles.Outport(i),h1.Inport);
    
    % get(porthandles.Outport(i)) % to see all properties
    name =get(porthandles.Outport(i), 'PropagatedSignals');
    
    linehandle = get(porthandles.Outport(i), 'Line');
    set(linehandle, 'Name',  name);
end
%%%% name all the signal lines according to outport-names
for i = 1: size(Msg.Signals,1)
  linehandle = get(porthandles.Outport(i), 'Line');
  set(linehandle, 'Name', Msg.Signals{i});
end
