Schematic document

Every electronic design should start with a schematic, documenting the logic and functionality of the design. In Fusion schematic diagrams can consist of as many as 999 sheets. The schematic diagram has two fundamental purposes:

• To communicate the intent of the original concept
• To provide a basis for the layout of the printed circuit board (PCB)

The basis of the schematic is the component, which represents a physical part in the design. Components are connected by nets, which represent the electrical connections between components. The Fusion schematic editor provides a range of tools to help you create and edit schematics.

To communicate the intent of the PCB, reference designators are assigned to each component. These are alphanumeric codes that identify each component on the PCB, and the number of symbols per component. Reference designators also indicate where all the components in the Bill of Materials (BOM) are located on the board. Finally, in addition to the bill of materials, the schematic can be used to generate a netlist, which is a list of all the components and their connections.
