• Note - It is often highly desirable to label the
  nodes
• of a Schematic for plan and simple clarity.
  PSpice will
• refer to nodes by N00004 for example.
• Labeling the nodes V1, V12, etc improves
  efficiency.
• See the NI button.
• Click on NI
• Type in node name i.e. V12
• Move cursor (or is it curser)to node and click to
  attach.

Adding Schematics Pages to a Design

• Root Schematic - to most sheet in the
  hierarchy.
• Page - Where the circuit diagram is found in
  the schematic hierarchy.
• Schematic - subservient circuit which can be
  called or descended to from the Root Schematic

41

• Add a new Schematic by right clicking
  on\dc1.dsn
• Root Schematic - you may have only one root.
• Note \ identifier a root.
• Add a new Page to any Schematic by right clicking
  onSchematic
• Rename Pages or Schematic by right clicking on
  either.

42
Adding Schematics Pages to a Design

• It is a good idea to place all of the circuits on
  a given subject in the same design.
• This will allow you to make calls of these
  subcircuits schematics from the Root
  Schematic.
• This eliminates duplicate reentry. More on this
  later.
