Schematic and Symbol Editors
Schematic and Symbol Editors Overview
The Schematic and Symbol Editors allow you to create, view, and edit schematics and symbols as part of design entry. A schematic is a graphical representation of your design. Symbols are the basic elements of a schematic and represent references to other design elements, such as IP cores or HDL modules.
Schematic Editor
Use the Schematic Editor to do the following:
  •  Create a top-level schematic that you use as input for the Behavioral Simulation step or Synthesis step in the ISE® design flow.
    Note You can define lower levels of a schematic design using schematic files, HDL files, IP cores, or state diagrams.
  •  Create a lower-level schematic to instantiate in a top-level schematic.
  •  Create a lower-level schematic to instantiate in a top-level Hardware Description Language (HDL) file.
  •  Save schematic files for archiving or view them as read-only HDL files.
Symbol Editor
Use the Symbol Editor to do the following:
  •  Create a new symbol to instantiate in a schematic.
  •  Edit an existing symbol to instantiate in a schematic.
