Hi,
I am trying to learn how to use gschem and gnetlist but I can not get
them to work even for a simple
RLC circuit. Running
gnetlist -g drc rlc.sch -o rlc.txt
on the schematics rlc.sch gives the following output
I think the first question I need to ask is what do you want to
do with gschem and gnetlist. That particular command that you are running
(drc or drc2) is running the design rule checker and it seems to be working
okay.
I would like to simulate the workings of a passive filter for a 2-way
speaker design.
So, use gschem to produce a schematics of a filter. Use gnetlist to
produce a netlist file
in order to use spice. This is my first experience with the geda suite
and its various components.
I have to say that I read a whole bunch of tutorials and could not see a
single complete example
which did not produce errors when I ran gnetlist -g drc ...
When you say drc or drc2 seems to be working, what do you get for the
output when you
execute gnetlist -g drc rlc.sch -o rlc.txt? I get a whole bunch of errors.
I would appreciate if you send me your output file for the circuit rlc.sch.
Both drc and drc2 are in the man file for gnetlist.
I included the output file in the attachment (rlc.txt). Perhaps someone
can decipher it for me, to whom I will be grateful.
I can not quite understand which attributes to specify for various
components to get my schematics to work.
Does anyone have an example of a simple RLC circuit that works? Or even
better, can someone point the mistakes
in the rlc.sch which I include in the attachment?
What do you mean by works? Do you mean simulate? If so, then
really should read the spice-sdb tutorial at:
Yes, I mean simulate or produce output without errors. Simulate is
perhaps too early to use because
I have yet to get to using spice. I actually read this tutorial. The
examples of errors that are given in the tutorial that
one may get using gnetlist are different from the ones I get in my
rlc.sch example so I do not know how to proceed.
Thank you for your reply. Hopefully you will be able to answer a few
more questions that I asked above.
I feel, if I can just get started with a very simple example than I will
be able to consider more complex examples
and eventually simulate my filter.
