 GND, VCC, 0V, +5V, -5V, etc.&lt;p&gt;
 Please keep in mind, that these devices are necessary for the
 automatic wiring of the supply signals.&lt;p&gt;
 The pin name defined in the symbol is identical to the net which is to be wired automatically.&lt;p&gt;
 In this library the device names are the same as the pin names of the symbols, therefore the correct signal names appear next to the supply symbols in the schematic.&lt;p&gt;
