What is the command line way in MATLAB to find the hierarchy of a signal name used in a Simulink model with subsystems ?

I have a Simulink model which consists of a top level model and subsystems. I use the same signal name in the toplevel model as well as within a subsystem. I would like to access the hierarchy of the signal name being used in my composite model, which will enable me to understand in which block the signal is existing.

In the attached example model below, use the following commands on your MATLAB command line in order to see the various levels in which the signal 'x2' is used.

The command line way to access where the signal 'x2' is used in a model with subsystems:

p = find_system(gcs,'FindAll','on','Type','line', 'SegmentType', 'trunk','Name','x2');

get(p(:), 'Parent');

The ouput yields the subsystem level hierarchy of the signal first and continues up to the top level usage of the signal in the composite model.

Analysing the output after updating the model and executing the commands mentioned above, 'x2' is used in the following levels:

'vdp_example/Subsystem'

'vdp_example'
