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');
