Every symbol needs some attributes (name=value pairs) in order
to be useful in lepton-schematic
, and in other tools.
First we’re going to add all of the attributes we want, then make the ones that need to be invisible invisible.
DIP14
or DIP40
.
Please see the footprint naming conventions page for further detail. If you are
using gEDA / PCB, also see the
PCB documentation and
gnetlist/docs/README.pcb for more info on this attribute and how it is
used.
Now that those have been added, make the numslots, footprint, description, graphical and device attributes invisible. Leave only the value of the refdes attribute visible, and place it somewhere at the top of your symbol.

into the entry field and press ‘OK’.
Note: Translating the symbol to the origin is a required step. To translate a symbol elsewhere, enter a offset (in mils) which is a even multiple of 100. Make sure all pins are snapped to a 100 mil grid point.

but if there are multiple symbols for a device
then this number simply increments.
This section describes the various requirements which must be met in order to create a valid symbol which will display and netlist in the gEDA/gaf system.

sequentially starting at 1.
