Co-Sim is running endlessly and not finishing

As you can see, my co-simulation has been running like this for over 2 hours. What could be the possible causes and how may I resolve it?

This isn’t a PYNQ issue. Please check/post on Xilinx forums.
Large designs can take a long time to run. There could also be an issue with your testbench/your code.


The co-sim runs perfectly on smaller datasets. So, I guess it rules out the possibility of an error.
Thank you for your suggestion, I will post it on Xilinx.
