Connections
Parts and ports contain one or more pins where
connections are made. Electrical connections are formed
by wire and bus segments joining pins and other wire and
bus segments. Connections are also formed by attaching
pins directly to pins. PSpice Schematics represents each
such electrical connection by a junction. Junctions are
made visible when three or more connected items
converge at the junction. Junctions are created and
removed automatically.
Some parts have hidden pins. Hidden pins are most often
used for power and ground connections to digital parts.
Hidden pins are not connected by wires and buses, but
rather through an attribute that names the net, which they
belong (the
IPIN(<pinname>)=<netname> attribute) to.
