#1 SPICE!
Mike Engelhardt, the author of LTSpice and it's maintainer for many years (up to 2019) left LT/Analog Devices and joined a new company, Qorvo.
He's spent the last three years developing a completely new and he claims FAR better SPICE called... QSPICE. He says that it's the SPICE he would had written had he known what he knows now...
QSPICE is available for free from https://p.qorvo.com/qspice-simulator.html
Deffo worth a look. Remember it's early days - it's only been in Beta a month and LTspice has been around for 25 years (initially in 1998).
Be interesting to see if Mike's name is enough to get other semiconductor manufacturers to provide models etc. There is no LTspice->Qorvo migration tool and Mike has explicitly said that if there is one at some point, it won't be him that writes it (almost certainly an anti-competition clause in his severance agreement with AD).

Very interesting - might give that a whirl. Hopefully there'll be a version for us awkward Linux types in due course...

Just had a look and Qorvo have some SiC FETs and jfets that might be interesting in mofo use. They have wide DC areas on their soa curves.
Whenever an honest man discovers that he's mistaken, he will either cease to be mistaken or he will cease to be honest.

I've been doing my latest Spice sim work in KiCad (as that does run on Linux), works surprisingly well actually.Michael L wrote: ↑Sun Sep 03, 2023 10:46 am....and Mac!Thermionic Idler wrote: ↑Sun Aug 20, 2023 11:07 am Very interesting - might give that a whirl.

Spice is a synthetic drug . In Manchester it coined the term 'spice zombies' because of the persona of people partaking in the drug on the streets of Manchester.

SPICE ("Simulation Program with Integrated Circuit Emphasis") dates from the mid 70's.

I worked on a precursor to SPICE when at Southampton University... it was called SUICIDES (catchy name, huh?)
Southampton University Interactive Circuit Integrated Design Engineering System... we had a competition to name it and that won... cheery place to work...
Written in FORTRAN 4 on a Honeywell DP516 (with rotating drum storage and 24kb of RAM plus a bunch of core) and then moved to a Modcomp Max 4 rev D.

You just have to watch out for the sand worms.
The world looks so different after learning science. For example, trees are made of air, primarily. When they are burned, they go back to air, and in their flaming heat is released the flaming heat of the Sun which was bound in to convert air into tree.
