Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.2 and earlier, you may see that simulation scripts are not generated by running Tool > Generate Simulator Setup Script for IP... without any warning or error message. This problem occurs there are a large number of IPs and the process times out before it completes.
This problem is fixed beginning with the Intel Quartus Prime Pro Edition Software version 21.3. For previous versions, generate the simulator setup script by command line as below:
ip-setup-simulation --quartus-project=<project name> --revision=<revision name> --output-directory=<output directory>
