No Linux version??
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Until Qspice can read the existing .asc files and libraries I doubt it comes to a significant move from LTspice to Qspice..

It might be WINE compatible. Like LTspice.

Unfortunately most software isn't Wine compatible. I have given up on trying to use Windows software on Wine a long time ago.

Wine has improved a lot over the past decade. I guess whether it runs "most" software depends on your sample. But LTspice has been running well for a long time already.

It does. The only thing that does not is updating LTSpice itself from within the app. But updating components does work.

LTSpice is purposefully (used to at least) build to be compatible with WINE.

People have been saying that for decades  ;D But realistically, QSpice is Windows 10/11 only so likely needs the latest .Net and Windows APIs to work. How far along it Wine with that? And even then, chances are high QSpice (or any other program) use a sequence of API calls that work differently that expected. If you look at the supported software list from Wine you'll see Wine needs to be tweaked/fixed for most software to work OR the software must be made to be compatible with Wine (which seems to be the case for LTSpice but LTSpice doesn't have a particulary demanding GUI to begin with).

In the end it makes much more sense to write new software cross-platform from the start rather than relying on emulation nowadays.

I am just about to install it. What upsets me a bit is the online installer. Does anyone know if there is an offline installer?

I have no intention of installing it.

What does it offer, which LTSpice does not?

Supposedly better performance with lots of digital logic and higher quality graphics or something like that.

I wonder if there are any plans to make it run on different CPUs like perhaps ARM - currently "Intel" is spelled out quite explicitly in the description.
Probably none like with LTspice ::)

LTspice license excludes my employer (thus me) from using it. pSpice is too bloated for most of my simulations.

Out of curiosity, what part of the licence excludes your employer from using it? I don't recall it prohibiting commercial use.

Their website is down for the second day in a row: "Site Temporarily Down for Maintenance We apologize for the inconvenience. Please try again in a short while.".

Too bad, I wanted to try a new UI :(.

The website is up again, but it seems the Qspice stuff is not there.
The former download link was this: https://p.qorvo.com/get-qspice

Just tried installing it under Wine, but the installer fails immediately with the attached error message. And yes, I have tried both setting Wine as Windows 10 and Windows 11, and yes, in 64-bit.
I guess the installer's method of identifying the OS recognizes it as not being Windows for some reason. So, it *may* work under Wine if the installer allowed it. Who knows.

If the author is interested in testing QSPICE under Wine, I'll happily do that once the installer is updated to allow it.

I gave up on WINE for QSPICE when I saw it converted DirectX12 calls to GDI. The problem is that that will be too slow and have pixelated graphics like the 1970s Pong game. I don’t see a path to getting QSPICE to a viable point on WINE. I’ll revisit it when WINE implements with DirectX12 API.

Interesting take, I wonder how long he's had it under development. I've not looked at WINE in awhile, but there are commercial games that can run under WINE. By comparison to most games, circuit simulation graphics would be considered primitive. Then I just did a quick Google, and as of WINE 4.0 (Dec 2022?), it has support for DX12 through the Vulcan library.

I see, thanks.

I personally don't see a point in requiring DX12 for a Spice simulator though to begin with. It's absolute overkill. Oh well.

Yep, banned at my job too. It is very annoying, but for my limited needs random online simulators do the job.
