Creating a New Design File

To create a new design in the FPGA Editor, follow these steps.

1. Select File New or click on the New toolbar button.
   
   
   
   The New dialog box appears, as shown in the “New Dialog Box” figure of the “Menu Commands” chapter.
   
   
2. Select the Design option.
   
   
3. Enter the design name in the Design File field. If you do not enter the .ncd extension, it is automatically added when the file is created.
   
   You can open a new design under a directory other than the current working directory. Type in the path name of the target directory in the Design File field, or use the browse button to select your target directory and specify your design file name.
   
   
4. In the New dialog box, enter the constraints file name in the Physical Constraints File field, or use the browse button to specify the directory and file name. If you do not enter the .pcf extension, it is automatically added to your file name. If you do not enter a file name, a constraints file is created with the same name as the .ncd file but with a.pcf extension.
   
   
5. Click the Select Part button to display the Part Selector dialog box, shown in the “Part Selector Dialog Box” figure of the “Menu Commands” chapter.
   
   
6. Select a Family, Device, Package, and Speed Grade for your design.
   
   

   Note: You can only select a part number from a part library you have installed on your system.

7. Click OK. The Part field in the New dialog box is filled in with your selections.
   
   
8. Click OK to close the New dialog box.
   
   An empty (unprogrammed) design is loaded into the FPGA Editor window with the part number and speed as specified.
