# Arrows on connections in schematics

Im using eagle, and was wondering how i'd produce arrows like this:

Is there a specific name for these? That show connections between many schematics.

• I call them I/O lines, but don't know if that's common. The line like CE is an output for this circuit (but will be an input on another circuit), and the MISO for example is an input for this circuit. There's also a line with two arrows, on both sides one, and that's input/output. But once again, these might not be common names. – user17592 Jan 23 '13 at 17:37
• Those are called "ports" in Altium, possibly the same terminology in other CAD software. – dext0rb Jan 23 '13 at 17:38
• Eagle doesn't have this as far as I know. It's only connected through net names. You can place net labels above the wires to show it. – Gustavo Litovsky Jan 23 '13 at 17:49
• Those arrows are labels or net names. They assign a name to the net a.k.a. wire. This way you don't have to actually draw wires between parts, you can simply drop labels on your devices pins/ports and avoid the spaghetti mess of wires. In kiCAD you have local and global labels. Local labels are for the current schematic sheet. Other schematics that are part of your project are on different sheets. You can bridge them using global labels. – Mister Tea Feb 5 '15 at 6:57

You have to use the NAME tool now . Just type: name MY_NEW_NET_NAME_HERE into the command box at any time then click twice on the net you want to rename. You can rename two nets to the same name doing this and they become logically the same NET. The label tool simply visibly shows what the underlying NET name is.
