Creating a New Implementation Revision

After you create a design version, you can try different implementation strategies on that design. For instance, you can reduce area, increase speed, and vary placement effort. Each set of implementation strategies makes up a new implementation revision. Generating new implementation revisions allows you to vary how your design is implemented in order to achieve your design objectives.

You can select new options or target a new device to change the way your design is implemented. Targeting a new device allows you to try your design in various devices to determine the most suitable fit. For example, if a particular device proves to be too large or too slow for your needs, you can select a smaller or faster target device from a different family.

When you create an implementation revision, an implementation revision icon is placed in the Design Manager project view. Each time you create a new implementation revision, you must enter the name and target part of your design. The implementation revision name, implementation state, implementation status, and any user comments for the implementation revision are indicated next to its icon in the project view when you process the implementation.

Replace or delete implementation revisions that are no longer useful.

To Create a New Revision

1. In the Design Manager project view, select a design version icon.
   
   
2. Choose Design New Revision from the Design Manager menu or click the New Revision toolbar button.
   
   
   
   The New Revision dialog box appears, as shown in the “New Revision Dialog Box” figure of the “Menu Commands” chapter.
   
   
3. Enter the name for the new implementation revision. Use the characters A through Z, a through z, 0 through 9, period (.), underscore (_), or hyphen (-) only. The name should be unique within the design version.
   
   
4. Enter any comments in the comment field. Use this field to note options and strategies.
   
   
5. To choose a device from the Part Selector, click Select.
   
   The Part Selector dialog box appears, as shown in the “Part Selector Dialog Box” figure of the “Menu Commands” chapter.
   
   
6. Specify the desired settings in the Family, Device, Package, and Speed Grade pulldown menus. For more information on these settings, see the “Part Selector Dialog Box Options” section of the “Menu Commands” chapter.
   
   
7. Click OK.
   
   
8. In the New Revision dialog box, click OK.
   
   The Design Manager creates a new implementation revision and displays its icon in the project view.
