Quartus IP upgrade (every time the file is loaded)

[KAshcraft]

All,

I can go through and perform the IP Upgrade on a project... then save the project.. then close the program and restart the program and load the project and I have to do the IP Upgrade again.

I've done the IP upgrade at least 5 times and it still keeps wanting the IP upgrade. 

Win11

Quartus 24.1

mainly schematic capture and Verilog mix

Thanks,

Keith

What IP?  What are you seeing?  Screenshots would help.

They were lpm_compare from Quartus 16 when I migrated up to Quartus 24. 

Since there were only 6 of them, I just deleted them out of the project and used the current IP Catalog and made new ones.

Not a biggie, but frustrating.

Thanks,

Resolved (just not automatic)

can't figure out how to update the Discussion label, so added a reply.

Sorry for the late reply,

This IP comes from Quartus 16, and unfortunately Quartus is not backward compatible with versions that old. If you try to upgrade, you’d need to go step by step—first through Quartus 18, then 20, and eventually 24. The simpler and more reliable option is to delete the old IP and create a new instance in your current Quartus version.
