Any cheap systems that does that?
With (relatively) modern op-amps?

I love to cook with wine. Sometimes I even put it in the food.

If you mean push a button and Spice runs on the schematic you've just
created then you've been using Spice on Unix Mainframes (with text command
files) too long.

Most of the PC versions of Spice do that nowadays.

This group has mentioned free and other versions. LTSpice does that.

If this is not what I had to fire up my crystal ball to figure out what you
were talking about then blame it on the cheap crystal balls nowadays.

LTSpice. Download from Linear Technology.
Cost: free. Is that cheap enough?
Has all the latest Linear Tech opamps. You can add your own devices to
the library.

I take it that LTSpice is low cost or free; lets me create a

schematic and runs SPICE on the schematic.
And what if the libraries do not have the op-amp you want to use?
Can one use others (like the old DOS versions of SPICE does)?
Could you name a few of the others; i am on POTS and downloading 10
megs or more is simply not practical.
I am willing to pay for a CD (hat is how i get versions of NetScape).

Thanks for the info.

It seems that Linear Technology does not have LTSpice available for

download. Furthermore the only version available seems to be exclusively
for switchers.

LTSpice is just our pet name for it, it is called LTSwitcherCAD, or something
like that.

As I understand it, the program is funded as a marketing tool for LT's switching
regulator division, but it is really an extremely full feature spice simulator
with switching regulator extensions.

SwitcherCad is LTSpice, certainly aimed at their
line of switcher-chips, but with more general Spice
libraries and capabilities bundled in.

I downloaded it with a 28k8 modem, (at British
Telecom's, pay_through_the_nose connection charges),
and the cost was trivial compared with the value
of LTSpice.

Stop wavering. Download it. You won't regret it.

Chuck,

available seems to be exclusively for switchers.

LTSpice is just our pet name for it, it is called
LTSwitcherCAD, or something like that.

The "official" name is LTspice/SwitcherCAD III. There
was once an edict to change the name simply to LTspice,
which is the name I prefer but I didn't want to lose the
name recognition of "SwitcherCAD", so both LTspice and
SwitcherCAD III are intended to be synonyms. BTW, the
"III" did not come from the "3" in SPICE3. It was the
third major piece of the sales collateral called
"SwitcherCAD". Also, the preferred case is LTspice,
not LTSpice. It's a trademark. I'm not interested in
hearing how messy this all is -- it's what happens to
get the thing funded.

Maybe I should bow to an example from the music industry
and change the name to some unpronounceable symbol. Then
we'd have "The Simulator Formerly Known as Either
LTspice or SwitcherCAD III."

As I understand it, the program is funded as a
marketing tool for LT's switching regulator division,
but it is really an extremely full feature spice
simulator with switching regulator extensions.

I'll call it anything you like for such a low cost (free) quality tool.

Thanks for your efforts.
