1.3.4 Blocks and Floorplanning

When creating a block, floorplanning is essential if you plan to publish placement information. Before running layout on the block, you must floorplan the design block. Use Libero’s MultiView Navigator (MVN) or PDC commands for floorplanning.

If you do not create a region and constrain the block to the region (floorplanning) or lock the macros before place and route, a warning message appears when you publish the block. It warns you that not all macros in the block have been constrained to regions or locked and therefore your design netlist is only exported when the block is published.
