Hi,
I am currently experimenting with geda and ngspice to simulate basic
circuits (for a Circuits Analyses course). I drew a basic circuit in
geda and exported it as netlist and got:
#######################################################
$> gnetlist -v -g spice-sdb sch_1.sch -o sch_1.net
... (followed by lots of output) ...
$> cat sch_1.net
* gnetlist -v -g spice-sdb -o sch_1.net sch_1.sch
*********************************************************
* Spice file generated by gnetlist *
* spice-sdb version 10.9.2004 by SDB -- *
* provides advanced spice netlisting capability. *
* Documentation at http://www.brorson.com/gEDA/SPICE/ *
*********************************************************
V1 2 3 10V
R2 1 3 50K
R1 2 1 100K
..END
#######################################################
I was wondering:
1. How can I specify within geda which nodes I want monitored during a
simulation? Or do I specify them on ngspice command line, or in the
output .net file?
2. How do I export the schematic so that I can include it in a LaTeX
file (as PS file perhaps)? I tried exporting it as PNG but I get the
whole big 'sheet' with my tiny circuit in the middle.
3. How do I change the size of the 'sheet' or paper so that it is just
big enough to accomodate my little circuits?
thanks,
->HS
