I just modelled a P-Channel MOSFET in Eagle and now would like to do duplicate the device to make slight changes to both the symbol and the device for a similar N-Channel MOSFET.

I've searched and googled but I can't seem to find a way to copy the entire device to do this.

  • \$\begingroup\$ As far as I know, you can duplicate a symbol (selecting the group command, then enclosing the entire symbol with a rectangle, then selecting a copy command; then creating a new symbol and doing a paste). But you can't do this for a device; there is no copy or paste commands in the toolbar for a device. So you have to take your new symbol, make a new device, and reassign a package and pins to it. \$\endgroup\$

To create the new symbol:

  1. Go to the library.

  2. Create a new symbol for the N channel FET.

  3. Go to the symbol for the P channel FET.

  4. Group all of it, then do CUT.

  5. Go back to the new N channel symbol.

  6. PASTE

  7. Modify from there.

Then create the new N channel device, referencing the new symbol.

  • \$\begingroup\$ Olin is correct. In case anyone is confused, the CUT command in Eagle acts more like a COPY :) \$\endgroup\$

  • \$\begingroup\$ @bitsmack: Yes, Eagle has some strange command names. As you mentioned CUT does a COPY, and the actual COPY rarely does anything useful. Another one is how WIRE is used to draw lines except when they represent wires, then you have to use NET. \$\endgroup\$ Jul 9, 2014 at 11:39
