Hello group,

I'm looking for SPICE software recommendations, both freeware and for
purchase. Whose programs do you use, and why?

Thanks,

Francis.

SIMetrix SPICE is very good:

That's easy: LTSpice, also known as LTSwitcherCAD, from Linear Technologies.

It is free, and is probably the fastest, most likely to converge, and all around
best spice package available.

It seems to be one of the few free SPICE packages out there that's "actively"
maintained and improved upon these days... Linear Tech made one smart choice
in having Mike Engelhardt write them LTspice from scratch -- his skills
definitely seem to be on the level of the folks who once worked on PSpice, and
if it were a team of people rather than just Mike himself, I have no doubt
that LTspice would rapidly start having the much fancier graphing and
scripting abilities that, e.g., PSpice does.

For commercial packages John Warner's SI-Metrix is pretty nice. Last I heard
he was maintaining SI-Metrix with just a couple of other people, and was
looking to hire more if he could find appropriately talented individuals.

I'll put my vote in for LTspice. Free, works well, PSpice compatible

syntax, and if there's a bug, Mike E. fixes it pronto. I've seen him
fix bugs in a matter of hours! Mike will also add user recommended
features when he sees fit. I find myself using LTspice over PSpice for
most small tasks since it is easy to use.

I like PSpice for the graphing capabilities, the one thing where
LTspice doesn't shine.

It is not free, but I'll definively vote for Labcenter's VSM
(http://www.labcenter.co.uk/index.cfm), as we are using it nearly daily with
pleasure : very good spice frontend with full graphics capabilities (if you
buy the advanced simulation option), real time simulation (turn a
potentiometer and see the effects), usable also as mixed signal simulator
(your prefered microcontroller simulated with the analog parts...) and PCB
design too.

Friendly,
Robert

What don't you like about LTSpice's graphing?

You should see the graphing of my DSO when you use its math functions.
Nice Taiwanese bonbon colors. But luckily it has an Excel interface and
there you can customize everything.

LTspice graphing dislikes:
1. Can't lock the scaling. This is my number one gripe about LTspice
graphing. The workaround is a few button clicks to recall saved graph
setup parameters.

2. Can't separate the graphing window from the main app window (nice
for dual monitor setup, schematic on one monitor, graph on second
monitor).

3. Doesn't have the equivalent of PSpice's Performance Analysis which
is handy for parametric runs.

4. A few years ago, didn't support cartesian coordinate display in AC
analysis. However, Mike added that feature which sidelined PSpice.

Ok, I can see that. Mostly I use SPICE just for "what-if" quick checks
where most of this didn't matter and I don't have a dual monitor setup
at the big PC (yet).

I'd do that as well but it would become quite cramped in here. The
office desk is huge but the corner location is occupied by a laptop and
the other desk space is needed for paper.

An office laptop is essential. Like this morning when the electricity
was gone. The utility was amazing, 1/2h later jack hammers were heard
and another hour later power was back on.

BTW, did your nfilter catch any gmail junk in the last couple of hours?
I just wedged a blanket-filter for gmail into Thunderbird and it's
awfully quiet now.

I no longer specifically filter on gmail. Since I added
"googlegroups", "aioe", "uar" and "remailer" to nfilter I'm seeing(*)
NO spam.

(*) Actually I'm still watching the filter action to separate out the
"good guys", but that test seems about over... very few "good guys"
use googlegroups.
