gEDA-user: gnetlist missing features

[Stefan Salewski <mail@xxxxxxxxxxxx>]

There was some discussion about netlist generation on this list
recently, so maybe it is a good time to speak about missing features:

I have some OpAmps with power down pins (active low) in my schematics, I
have connected an io symbol to it with an attribute like
"net=PreAmpPD:1".

If I connect this io symbol (a copy) to an other device, i.e. to a pin
of an FPGA all is fine. Now I decide this OpAmp should be always on, so
I make a copy of this io symbols and connect it to a (lonesome) power
symbol with a net attribute like "net=3.3V:1". So the power symbol and
one instance of the io symbol are connected to each other, with no
direct connection to other real hardware. I think this will not work
correctly, the power down pin of the OpAmp will not be connected to the
3.3V rail as desired.

It would be very nice if this would work -- I think we had a discussion
about this problem long time ago on the list.

The other topic: There are ICs with multiple power- or output pins for
low impedances. It would be nice to allow "pinnumber=4,5,6,7" in symbols
to indicate that this visible power pin in the schematic should indicate
a connection to pins 4,5,6,7 of the related footprint. (My current
solution is to make a local copy of the footprint, have "pinnumber=4" in
the symbol and rename pads 4,5,6,7 to 4,4,4,4 in the footprint and so
on)

Best wishes,

Stefan Salewski
