I am working on documenting a Matlab + Simulink code which was written by someone else.
I have no problem understanding the Matlab code by Running the code using the "Step In" option available in Matlab .
The issue I have is, when matlab transfers control from Matlab file to Simulink, using the function call "sim(model_name,parameters)"
When I continue the "Step In" after the program control gets transferred to Simulink, Matlab opens "fullfile.m" instead of the Simulink blocks
How do I "Step In" each block of Simulink when the program control gets transferred to simulink ?

This would be difficult. If you do need to debug any issue with the Simulink model simulation, I would suggest you do it separately with the Simulink model.
Open the Simulink model, Click "Debug" at the top menu tab. You can trace signal values, add break point, run step by step, etc. But it will be different than debugging code line by line.
Once you resolved the issues with the Simulink model and make sure the simulation is correct, then focused on debugging the MATLAB code.
