Tic Toc Equivalent for Simulink

I am trying to understand how long different portions of a complex simulation are taking in real world time. In MATLAB, I would use Tic Toc to time and analyze different portions of my code. How can something similar be done in Simulink?

• I want to be able to drop this block at different points in my schematic and save the real world timestamp every time the solver reaches that point in the code (Not needing an initialization block would be ideal)
• Each block put into the schematic must be labelled with an assigned variable
• Time information for each block should probably be written to a File, maybe to the Workspace
• Basically, looking for a method to "Flag" real world time at different points in my schematic

In the particular case of Simulink Desktop Real-Time, see https://www.mathworks.com/help/sldrt/ug/execution-time-measurement-and-block-profiling.html

Otherwise, there are some possibilities at https://www.mathworks.com/matlabcentral/answers/30479-how-to-get-system-date-and-time-into-simulink and more modern at https://www.mathworks.com/matlabcentral/answers/439015-get-unix-standard-timestamp-on-matlab

If you want to "tic toc" an entire model, there is this script on the File Exchange (full disclosure, I am the author): https://www.mathworks.com/matlabcentral/fileexchange/72854-model-execution-time
