Step 2: Instantiate the ARM-Based Excalibur Embedded Processor Megafunction

To instantiate the arm_processor symbol generated by the MegaWizard Plug-In Manager in the top-level design, follow these steps:

  1. Double-click an empty space in the Block Editor window. The Symbol dialog box appears automatically.

  2. In the Libraries list, click the + icon to expand the Project list.

  3. In the Project list, select the arm_processor symbol. A preview of the newly created arm_processor megafunction appears in the Symbol dialog box.

  4. Click OK to instantiate the arm_processor symbol in the BDF. An outline of the arm_processor symbol is attached to the pointer.

  5. To place the symbol, click to the right of the clk_ref and npor INPUT pins in the Block Editor window. The arm_processor symbol is instantiated in the BDF as shown in the following illustration.

    6. Show Me
    arm_top BDF

    arm_top BDF

    NOTE For simplicity, ports are arranged on the arm_processor symbol according to their stripe function.
