Cyclone 10LP 080 Timing Closure

Hi,

at some point in time I achieved timing closure for my design. I then made some changes to it, and now I get several thousand warnings when running timing analyzer. All of them are related to the filter-module, which I have 16 instances of, locked to logic regions.

Even if I revert back to the old filter-module, I still get warnings. 

I went from Quartus Prime Lite to Standard 25.1 in the process of achieving timing closure in order to access the logiclock-feature.

The "old" design (with successful timing closure) is built for at Cyclone 10LP 040, while the updated design is built for a 080-device.

Running Timing Analyzer I get this answer when asking for recommendations:

Is this related to optimization of the filter-module?

    ...and how to go about to resolve the timing issues? Could it be related to the switch from 040 to 080-device?
