Workflow (a project-based workflow)

  1. drawing a schematic: Schematic Editor. Which components are in the design and how they are connected.
    • custom symbols may need to be created if appropriate symbols aren't available.
    • footprints are also selected for each component
  2. laying out a circuit board: PCB Editor
    • footprints are the copper pads that match the pins on a physical component
  3. editing symbols: Symbol Editor
  4. editing footprints: Footprint Editor

1. Schematics. Connect through

  1. lines. (Gets complicated.)
  2. network labels.
  3. hierarchical labels. (Multiple worksheets.)
  4. global labels.
