USING LOGICLOCK REGIONS
118 ■ INTRODUCTION TO QUARTUS II ALTERA CORPORATION
Figure 3. LogicLock Region Properties Dialog Box
After you have performed analysis and elaboration or a full compilation, the
Quartus II software displays the hierarchy of the design in the Hierarchy tab
of the Project Navigator. You can click any of the design entities in this view
and create new LogicLock regions from them, or drag them into an existing
LogicLock region in the Timing Closure floorplan.
Altera also provides LogicLock Tcl commands to assign LogicLock region
content at the command line or in the Quartus II Tcl Console window. You
can use the provided Tcl commands to create floating and auto-size
LogicLock regions, add a node or a hierarchy to a region, preserve the
hierarchy boundary, back-annotate placement results, import and export
regions, and save intermediate synthesis results.
