If this would be related to the IP not appearing in the local catalog, you might try to use this approach:

(1) from C:\LatticeCore which is the IP repositories (if this is default), locate the IP that you have, copy the folder name

(2) from ipsetting.lst of C:\lsc_env, edit the .lst and copy the folder name and follow the format from the file. That is, {ip_folder_name}=C:\LatticeCore

On the catalog of the Lattice Diamond software, please refresh using the refresh button on the software. You should expect the update of the IP folder.
