Targeting the Design for the XC9000 Family

The incomplete calc_sch design is configured for an XC4003E-PC84 part. If you want to target a demonstration board with this device, go to the “Completing the Calc Design” section. If you are targeting the tutorial design for an XC95108-PC84 (no demonstration board available) or other device family, you must convert the design to reference the XC9000 library instead of the XC4000E library.

The procedure provided below allows you to change every Xilinx component in the Calc design from the XC4000E library to the XC9000 library. Since the designs were created using the Unified Libraries, the parts in the XC4000E and XC9000 libraries have identical footprints and pinouts. This allows you to easily retarget designs to a different device family, provided only library parts common to the two families are used. You must manually replace any library parts that are not common to both families. This example shows a situation where this may happen.

NOTE

Although an XC4000E-to-XC9000 conversion is shown here, this procedure may be used to retarget from any family to any other family.

To retarget the Calc design to the XC9000 family:

  1. Close the Calc schematic window by selecting Close from the window's control menu. This is the menu accessed by clicking on the button in the upper left-hand corner of the window.

  2. In the gray desktop area, choose Right Mouse Button Convert Design.

  3. A dialog box appears as shown in the figure below. Fill in the fields as shown and click OK.

    Figure 9.5 Convert Design Dialog Box

    Convert Design begins by displaying a Hierarchy Window as it is taking account of the design hierarchy. After this, the Calc schematic and all lower-level design schematics are displayed while Design Architect is retargeting design components.

  4. After this process is completed, perform the following for each schematic:

    1. Select Check Sheet from the menu bar. A window appears containing the results of the design rule check.

    2. After reviewing the contents of this window, close it and reselect the schematic window.

    3. Select File Save from the menu bar to save the schematic.

    4. Close the schematic window and repeat the process for the next schematic.

      NOTE

      Keep the top-level Calc design open, since you need it in the next section. You can also save yourself the step of checking and saving each design sheet by setting the Check & Save switch to Yes in the Convert Design dialog box.

      WARNING

      Although turning the Check & Save switch on makes the Convert Design process more automatic, it is more dangerous since it prevents you from inspecting a converted design before saving it. Use this setting with caution, and turn it on only when you are certain you wish to overwrite your original design.
