LTspice installs and runs well under wine in linux. (Use winetricks. )

I’ve been using it that way for years and years.

Ltspice is pretty good, the interface is a little clumsy, but
once you get past that it's ok. You can plop down your own text
models and connect them to the components with out much trouble.

The difficulty with the LTspice interface is that it uses "verb" mode instead of "noun" mode. In other words, you need to select the action and then the object, instead of the object and then the action. This differs from how a lot of other programs work. Also LTspice doesn't do schematics for PCB Layout, so you are concurrently using another schematic layout program which is a pain. I had changed LTspice's hotkeys to match Altium's to avoid hitting the wrong keys.

Schematics for PCB layout have requirements so different from
schematics for simulations that I don't even *want* to use the
same tool for both.

I have KiCad for one and LTspice for the other, both on a Linux
machine. I never simulate complete designs; only sections that
need closer attention.

It appears KiCads's eeschema can be used as a schematic entry
front-end for ngspice. I never yet bothered.

Allow me to confirm how KiCad's eeschema can indeed be used as a
schematic entry front-end for ngspice.

As alluded to above by Wanderer, KiCad keeps me from doing double work.
eeschema is also more intuitive, comprehensive, and easier for me to
use. YMMV.

Use Spectrum Software's Micro-Cap (latest version is 12.2.05) instead
of either of the above. Although popular, unless you want to simulate
Linear Technology's controller IC's, I cannot see any reason why
anyone with any sense would use it.

(Just to be clear I'm referring to LTspice.)

I agree. I only Spice subcircuits and don't use the same parts as will
be on the PCB.

Spice happens way before the PCB design.

I have 1616 LT Spice sim files in my project folders on this PC. I

I don't mind being dumb, but do I have to give all the money back?

LT Spice has earned us about a trillion times what it cost.

I have LTsice running in Linux in 'wine' windows simulator on some old PC.
Not that I use it much..
I have used it to draw filter curves, that is useful,
avoids lots of maaz or what was it matzs? anyways....

Seems this one's abandoned now? Which I guess isn't necessarily a
problem, unless the "download" links at archive.org don't work...

Thanks for the alternative suggestion too!

Thanks Phil, google was hinting that LTspice via wine "might" be the way
to go ... but then again, search results can be misleading, especially
when one doesn't know any better.

I ran across that myself yesterday evening, but not going to touch it
until I have a better handle on what rabbit hole I'm falling into here
(although it does seem that one "must" use ngspice to work with KiCAD,
if I'm read and understood the brief overview properly).

For a while I happily used LT spice in a vm box on Linux then acting on
advice of folk here found it was even easier under wine. Went down a rabbit
hole on first attempt using wrong repo of wine but within an hour had
sorted. Since then l use LTS under wine on most of my machines with no
problems.

That’s where winetricks comes in. Super easy.

Certainly LT Spice has killed a lot of other simulation software, and
companies.

I wonder if Raspberry Pi is doing something similar.

I mean, "Micro-Cap" was only killed off in the last year or two from
what Wikipedia says (otherwise having lasted 40 years). It almost seems
that the company was rather small and the owner(s) just closed up shop.

In what sense? I mean, there are a few handfuls of single-board PC
makers out there now all chasing the "XYZPi" name since "Raspberry Pi"
got big.

Yesterday I designed a 3rd order LC filter by just guessing and
tweaking in LT Spice. It's actual funtion is to generate a clean
CMOS-logic 1 ns time delay, for a guy who wants a ns of timing margin.

I can guess and tweak higher order filters. 5th order is my record,
but that's tough. You can diverge, get lost in space.

A dual-core CPU chip for 60 cents, RP2040, with 20 years of guaranteed
supply, and a $70 dev+debug system is hard to compete with. A
generation of kids will design around Pi chips.
