Spice2 to spice3 library converter

[Alex]

Hi,

I ran into the spice3 not handling POLY() statements issue.. looked for
a converter but couldn't find one so I wrote one. It works on a very
simple op-amp model, but is still _very_ untested, so watch out.

This gave me considerably more trouble to write than I thought it
would. Best way to handle the poly() is almost certainly to compile
ngspice with the right options. But if anyone can use a (probably
still very buggy) converter... here it is:

spice2to3-2005-03-14.tar.gz on
http://www.dnlnk.com/spice.html.

BTW, anyone know of a good Eagle netlist to Spice format converter?
Any interest in one?

regards,

Alex

AFAIK, most Spice derivatives, with behavioral capability, will STILL
run POLY.

But it shouldn't be too hard to write a script to convert the terms to
Algebraic notation.

...
Over the last weeks there have been different postings about the
translation of netlistfile from SPICE 2 in the SPICE 3-format. I have
written a little program (called "sppp" --> SpicePreProcessor), that
does this conversion automatically. The translator also converts several
PSPICE-extensions in a SPICE 3-like form. sppp does the following
things: - translates "POLY"-Sources into the new SPICE 3 syntax -
converts inlinecomments into normal comments - changes the syntax of the
device "K" (coupled Inductors) (single line notation with more than 2
Inductors in a multiline notation with only 2 Inductors each line) -
several PSPICE "Point commands" were modified or commented out sppp was
developed under LINUX with gcc V2.7.2, ELF-binaries. There are also
versions available for DOS and SunOS 5.5.
...

I'm look for this program (sppp) or other. The Author didn't answer me.

"sppp" seems dead-ended, no googling gets me anywhere.

Is it true that spice3 won't run POLY?

For Linux, use ngspice:

http://sourceforge.net/projects/ngspice

Download the sources (either rework or rework-devel are OK), and
configure using --enable-xspice. That is, build like this:

../configure --enable-xspice --with-readline
make
make install

Ngspice with XSpice enabled will properly handle netlists with SPICE 2
POLY constructs.

There is a SPICE on Linux HOWTO at:

http://www.brorson.com/gEDA/SPICE/t1.html

And this HOWTO talks about ngspice here:

http://www.brorson.com/gEDA/SPICE/x496.html

(scroll down a ways to get to ngspice.)

Good Luck!

Stuart

MacSpice

<http://newton.ex.ac.uk/teaching/CDHW/MacSpice/>

can translate spice2 poly into spice3 B sources rather well. If you
don't have access to a Mac just collect all the polys into a fake
netlist email it me and I'll send you back a translated version.
There is obviously a limit to the number of times I'll do this
before I get bored...

I will look to see if the variables HAVE_STRCHR or HAVE_INDEX are

Also, what version of glibc do you have?

Jim,

Truly strange. EVEN PSpice can read POLY extensions.

I've always had the impression that MicroSIM invented
the POLY() syntax because it was easier to parse and
differentiate then general syntax like V=3*V(x)*I(E1).
I see POLY() popularly accredited to SPICE2 in usenet,
but the string "POLY" doesn't seem to exist in the the
FORTRAN code of 2g6.

Nowadays, even the PSpice doc's frowns on POLY() syntax
as obsolete.

POLY CAN certainly be confusing.

You sure about POLY not in 2G6? I sure seem to remember using it.

Opps, you're right. Faulty memory. I just grep'ed
the 2g6 source and now I do see the function
evpoly(result,itype,lcoef,ncoef,larg, narg,lexp) in
the file evpoly.f

Yep, the MicroSim folks hated that function. It always
seemed to invite convergence errors and difficulties in
setting up the matrix properly. But, I think it was one
of those things that they couldn't really 're-code'
from the original...

I thought you told me you didn't know the original
MicroSim folks, one founder of which I used to retain. No
matter. Anyway, the POLY() syntax is much better wrt to
convergence then the alternative, arbitrary arithmetic
expressions. The advantage is that the POLY() syntax
limits you to a polynomial with all positive powers. This
is everywhere differentiable and is only singular at
infinite input. The arbitrary arithmetic expressions
can have negative powers and various functions that
aren't differentiable everywhere. The reason that
the POLY() is obsolete is that it's a terrible syntax
for the user, not for the convenience of the simulator
author.

I used to retain one of the original MicroSim founders.
Charlie tried to guess which one and said he hardly know
so-and-so -- that that predated his association. That's
what I based the first sentence on. Anyway, POLY() is
much easier to deal with with respect to convergence
then arbitrary arithmetic expressions like

E1 1 2 VALUE { if(V(x) < 1, 1/V(x), 1/V(x)/V(x)) }
