Schematic Designs With Instantiated CORE Generator Cores

Cores generated in the CORE Generator tool can be used in schematic designs. After the core is selected and customized, its schematic symbol is generated by the CORE Generator tool. The core can then be added to the schematic like any other library component.

Creating Core Symbols

To use the CORE Generator tool in a schematic-based environment, follow these steps:

  1. With a project open, invoke the CORE Generator tool from within the Schematic Editor (Tools CORE Generator).

  2. Select Project Project Options. Ensure that Design Entry is Schematic and that the Vendor is Foundation in the Project Options dialog box. The Family entry should reflect the project's target device. Click OK to exit the Project Options dialog box.

  3. To aid selection, the available Cores are categorized in folders on the View Mode section of the main CORE Generator window. Double click a folder to see its sub-categories. When you double click a sub-category folder, the available Cores are listed in the “Contents of” section of the main CORE Generator window.

    If you double click the name of the desired core, a new window opens to allow you to view its description or access its data sheet. (Acrobat Reader is required to view the data sheet.)

  4. To select a core to instantiate into a schematic, highlight the core's name (click once) in the “Contents of” window and then select Core Customize and enter a name for the core in the Component Name field.

    The name must begin with an alpha character. No extensions or uppercase letters are allowed. The name may include numbers and/or the underscore character.

  5. Other available customization options are unique for each core. Customize the core as necessary.

  6. Select Generate to create a schematic symbol and a simulation model for the selected core. The schematic symbol for the core is incorporated into the project library and can be selected from the SC Symbols list.

  7. Select File Exit to return to the Schematic Editor.

  8. In the Schematic Editor, select the symbol from the SC Symbols list (Mode Symbols) and place the core on your schematic.

  9. Connect the core to the other components on your schematic using ordinary nets, buses, or both.

  10. Complete your schematic by placing additional components from the symbol toolbox including I/O ports, nets, buses, labels, and attributes.

  11. Save your schematic by selecting File Save.

To complete the design, read the following sections in the order listed:
