4 years agoSo this is a new PLL instance that you just successfully generated, and when you try to reopen the parameter editor for it, you get that error? Or are you saying that you instantiated an old PLL instance that you've created previously and are trying to bring into 21.1? What device does your project target?
Try recreating the PLL from scratch from the IP Catalog.
