I'm working on an Arria10 design with about 30% fill, (i7-7820HQ @2.9GHz, 16GB RAM, Windows10)
Every time I want get a list of nodes (SignalTap: pre-synthesis) it takes more than 15mins+ to get the list.
Please share your experience how to fix this.
This is after running Analysis & Elaboration from the Processing menu? Very strange.
What's actually happening during the 15 minutes where you're stuck?
Before you do that, try quitting Quartus, deleting the db and incremental_db folders (if present) in your project directory, and re-run Analysis & Elaboration. Something could be corrupted in the compilation database that is causing the issue.
