Is it possible to use an EDIF or NGC netlist as a submodule partition within a Project Navigator design?
It is possible to use an EDIF or NGC netlist as a submodule partition within a Project Navigator design. However, Project Navigator will not keep track of whether or not these submodule netlists are up-to-date. If you alter the netlist, you must explicitly set that partition out-of-date for the changes in the netlist to be updated during the next implementation run. If you do not do this, the netlist partition will be preserved as if there were no changes made.
