How are power and supply pins used in Eagle?
Eagle will treat these, as it should, as separate nets. To tie them together, use the SHORT device in the attached shorts.lbr. This is merely two pads that overlap each other. This will produce a DRC error, but it can be approved to prevent from being a nuisance. 2) Power and Supply pins are more challenging. Some IC’s have VCC, others VDD.
Why are power pins not forward annotated in Eagle?
Such inconsistencies can occur if the supply pin configuration is modified after the board has been created with the BOARD command. Since the power pins are only connected “implicitly”, these changes can’t always be forward annotated
How to attach a pin not shown on schematic symbol?
It will let you hook up pins that are attached to default nets. If it were OrCAD you’d just use multiple names on nets or attach a Vcc bar to the 5V rail. This effectively means that any symbols with Vcc for pin 14 (or 16 or whatever) get attached to 5V because there is a netname of Vcc attached to 5V in the schematic.
What is the power pin El in ERC-MIT?
POWER Pin El._Name Pin_N. connected to Net_Name only one Pin on net Net_Name no Pins on net Net_Name unconnected Pin: Element_N. Pin_N. Junction at (x, y) appears to connect nets Net_Name and Net_Name NET Net_Name: missing Junction at (x, y) NET Net_Name: close but unconnected wires at (x, y)
Is the value of a power pin irrelevant?
The “value” is irrelevant. You can override the net to which a power pin of a component is connected, simply by drawing it explicitly. There will be an ERC warning but you can ignore (or approve) that. What you should do is create your own library of supply symbols with all the names you need.
Is it possible to defin a VCC symbol as like 12V?
Is it possible to defin a Vcc symbol as like 12V, an other 5V and when i connet them, the NET became the same that i choose as Value. Solved! Go to Solution. Solved by s.zambaldi . Go to Solution.
