command or tool. Highlight a net by marking its wires and net labels with a different color. If KiCad runs in project mode then copper corresponding to the selected net will be highlighted in Pcbnew as label/Label/LaBeL). Net names are case-sensitive therefore such labels are treated as separate nets. Test unique global labels Report global lables that occur only once for a particular net. Normally it is (options) toolbar. Eeschema automatically connects invisible power pins of the same name to the power net of that name. It may be necessary to join power nets of different names (for example, "GND" in TTL
