When importing LogicLock regions, you can click Advanced in the Import
Assignments dialog box to specify the nature of the assignments to import,
specify global or instance-level assignments to import, and specify how the
assignments affect the current design. You can also create a backup of the
current QSF for the design before importing assignments.
Using LogicLock with EDA Tools
The block-based LogicLock design flow supports modules that have been
created and optimized in EDA design entry and synthesis tools and then
imported as separate modules in the Quartus II software. You use an EDA
design entry and synthesis tool to create separate netlist files (EDIF Input
Files (.edf) or VQM Files) for modules in a design hierarchy, or to maintain
blocks of logic within a netlist file. You can then use the Quartus II software
