Can I list out/hightlight all inputs for a specific output

I want to, for a specific output, get all its calculation inputs.If they can be highlighted in Simulink model, that will be perfect.

You can write your own MATLAB script to trace an output signal to its input using get_param function and the handle of the signal. You can do something like:

 % example block name 
 block = 'model/subsystem';  

 % get block handle by name
 blockHandle = get_param(block,'Handle');  

 % get all port handles of the block
 portHandles = get_param(block,'PortHandles'); 

 % get block inport. May need to index if there are multiple inports
 inportHandle = portHandles.Inport; 

 % get input line handle that goes into the port
 lineHandle = get_param(inportHandle,'Line');

This can be done recursively until hitting a termination point that can be specified.

The hilite_system function can be used to highlight blocks and signals by their handles.

Starting R2017a, there is another way to highlight signals from Simulink editor.
