Due to a problem in the Quartus® Prime Pro Edition Software version 22.1 or earlier, you may see this internal error when you try to compile the design. This is caused by the Quartus® Prime Pro Edition Software trying to reach the Cloud Notification Center that has been marked EOL (End of Life).
To avoid this problem in the Quartus® Prime Pro Edition Software, follow the steps below:
1. Go to Tools, Options, Internet Connectivity, and turn off the Notification Center feature.
2. In your quartus2.ini file, remove any assignment that will try to reach the Notification Center.
The quartus2.ini file is located at:
For Windows OS, go to C:/user/<username>/
For Linux OS, cd to home/<user>/.altera.quartus
Example of cloud related setting that need to be removed:
CLOUD_SEND_END_FLOW_NOTIFICATIONS = on
CLOUD_SEND_REPORTS = on
CLOUD_SERVER = https://fpgacloud.intel.com
CLOUD_TOKEN = <secret>
CLOUD_USERNAME = <username>
3. In your .qsf file, remove any assignments that are tagged with dse_intenal. Example:
set_global_assignment -name CLOUD_NOTIFY_GROUP_ID 23485 -tag dse_internal
set_global_assignment -name CLOUD_NOTIFY_ENABLE ON -tag dse_internal
This problem is fixed beginning with the Quartus® Prime Pro Edition Software version 22.2.
