I have tried SoC (system on chip) basic 'closed loop control system' application using TI Delfino F28379D Launchpad
via MATLAB 2021b version. ( https://www.mathworks.com/help/soc/ug/get-started-with-soc-blocks-on-mcus.html)
All instructions (end of document , 1-6) were applied step by step. At the end of load and run provess, I didn't encounter any important errors on the Soc Builder and matlab command window like a following figures.Only warnings were observed. I think these warnings do not affect working principle of the system too much.
Mainly, I did not see the expected Sampled ADC Value results.
As you can see, In Actual (measured) Sampled ADC value(red) differs from expected ADC value. ADC measurement isn't observed.
What is the main problem ? Can you explain ? Manythanks for your helps.

If the software recommendations made by above commenters don't work, consider a hardware/connection issue.
Can you send a photo of the hardware setup you used to create the RC circuit? The fact that you are seeing a step response and reference go high, but no ADC results would indiciate a possible lack of connection. Either the RC circuit could be built incorrectly or the ADC sense was not connected tot he correct spot of the circuit. Do you have access to an oscilloscope to determine that the PWM signal is being generated as expected and connected to the RC circuit as expected?

I am assuming you are trying External Mode, in that case you had to connect the actual HW connection with F28379D launchpad (HW driving analog values to ADC pin of F28379D).
For PIL workflow the recommended steps are captured here https://in.mathworks.com/help/supportpkg/tic2000soc/ug/pil-simulation.html. And you need to setup your models differently and use SIL/PIL Manager app. Parent page for SoC Blockset C2000 PIL simulation can be found here https://in.mathworks.com/help/supportpkg/tic2000soc/setup-and-configuration-1.html
Check your PC RAM memory with that specified by MATHWORKS for the MATLAB version used.

Most probably it could be due to insufficient RAM memory. Please check your PC RAM with the version of MATLAB specific requirement.
