Input Files

The Floorplanner can read in the following input files.

• NCD
  
  This file is generated by either MAP or PAR. It is used by the Floorplanner during the File New command to generate the physical design for the FNF file.
  
  
• NGD
  
  This file is generated by NGDBuild. It is used by the Floorplanner during the File New command to correlate the physical design to the logical design when creating the FNF file.
  
  
• FNF
  
  A previous version of this file, which was generated by a File Save in the Floorplanner, can optionally be used in the creation of a new FNF file. If used, it helps retain design constraints between floorplanning iterations.
