Re: gEDA-user: gschem/gnetlist question

[Carlos Nieves Ónega <cnieves@xxxxxxxxxx>]

Hi Zoran,
the DRC checker is telling you the net is not driven. This means that
only input or unknown pins are connected to that net, and that net will
be theoretically floating.
The reason is that the pintype attribute is missing in the symbols. The
pintype attribute tells the DRC the type of each pin (passive, input,
output, open collector, ...etc).
If you want to fix this, you have to edit the symbols you are using and
set the pintype correctly. For R's, C's, and L's it should be
"pas" (passive), for example. I'm not so sure about the voltage
generator.... maybe one pin should be "out" (output) and the other
"pwr" (power)?
There are some symbols with missing pintype attributes. They have to be
fixed.

Regards,

Carlos
