Re: gEDA-user: Try to add component

[Stuart Brorson <sdb@xxxxxxxxxx>]

Just to expand on my answer a little bit...

The way the netlister works is this:

The top level does a bunch of preparation, like writing header info,
etc.  Then it calls spice-sdb:write-netlist, where the real action
occurs.

write-netlist runs through the list of components it has found.  The
list is a list of refdeses.  For each refdes, it tries to get the
"device" attribute of the component.  If it finds the device
attribute, and recognizes it, it calls the appropriate processing
function which writes out the correct line of SPICE code (i.e. SPICE
card).

If write-netlist doesn't find a "device" attribute it recognizes, then
it calls write-default-component.  This function makes a guess as to
what the component is, based upon the refdes.  That is, if the refdes
is D, then it assumes the component is a diode.  If the refdes is R,
it assumes you have a resistor.  Based upon this guess, it calls the
appropriate function which writes out the SPICE card.

In your case, you did not have a "device" attribute on your component,
and the write-default-component function did not recognize your A
refdes.  Therefore, it just exited with an error.

Therefore, add some code to write-netlist to recognize your "device"
option, and everything will be good.
