memory copy STM32F4

Hi, I'm using embedded coder block set for STM32F4. I use to generate .hex file of my simulink design from MATLAB and burn it to STM using KEIL uVision. Is there any way to visualize simulink variables in KEIL? I need to observe the variable values in run-time for debugging. I'm trying to copy values to a memory location using 'memory copy' block but it is not working. Any help will be appreciated

Regards.
