I am trying to simulate a simple phase locked loop model in simulink. But for some reasons, the time for execution is stuck at 0%. I assume, the system is not getting feedback. The signal is a sine wave with freq = 10 Hz and Amplitude = 2. The parameters for the rest of the components are as default and I haven't changed anything. I am a bit confused with the paramaters that I need to change(if) in VCO. I am new to this topic so if someone could guide me with this, I'd appreciiate it.

Hi Reema,
What version of MATLAB are you using? Could you zoom in on the scope output near 0s to see if there's any activity?
I would also recommend you to watch this related video:
