Opening a File

To load a design file in the Floorplanner, follow these steps.

1. Select File Open.
   
   This command opens the Open File dialog box where you specify which FNF file to load. In this dialog box, you can also change directories if the desired FNF file is in a directory other than the current directory.
   
   
2. Scroll the files list box until you find the desired design file in the list.
   
   
3. Double-click on the design file name or select the file name and then click Open to open the Floorplanner windows.
   
   When you load in an FNF file, the Floorplanner reads the file, loads the correct device (part type), opens the Design Hierarchy window with a hierarchical design, and opens the Floorplan window with the correct FPGA die.

   NOTE

   If an FNF file exists in the current directory and it is newer than the NCD and NGD files, the Floorplanner reads in the FNF file. Otherwise, it opens a dialog box that asks if you want to update the FNF file from the newer NCD or NGD files.
