A native Apple macOS 10.7+ application was introduced in 2013. LTspice was originally called SwitcherCAD, but that name was removed when IV was released. Though IV is still available for download, it is no longer maintained.

It is designed to run on Windows 2K, XP, Vista, 7 with a processor that contains a minimum instruction set similar to a Pentium 4 processor. Originally, LTspice/SwitcherCAD ran only on Microsoft Windows platforms, but since 2003 it is able to run under the Wine Windows compatibility layer on Linux. In June 2001, it was released for public downloading from the Linear Technology website. Initially, LTspice III was internally released to Linear Technology's Field Application Engineers (FAE) in October 1999, who then gave it away during customer visits via CDROM media.

This version is no longer available for download from Analog Devices. It is designed to run on Windows 95, 98, 98SE, ME, NT4.0, 2K, XP. In 1999, LTspice III was released, the first public release. It is used by many users in fields including radio frequency electronics, power electronics, audio electronics, digital electronics, and other disciplines. While LTspice does support simple logic gate simulation, it is not designed specifically for simulating logic circuits.

LTspice does not generate printed circuit board (PCB) layouts, but netlists can be exported to PCB layout software. It has enhancements and specialized models to speed the simulation of switched-mode power supplies (SMPS) in DC-to-DC converters. Heat dissipation of components can be calculated and efficiency reports can also be generated. Circuit simulation analysis based on transient, noise, AC, DC, DC transfer function, DC operating point can be performed and plotted as well as fourier analysis. LTspice offers you the ability to rapidly prototype your designs so that you understand them betterand even develop intuition.LTspice provides schematic capture to enter an electronic schematic for an electronic circuit, an enhanced SPICE type analog electronic circuit simulator, and a waveform viewer to show the results of the simulation. I believe SPICE has impacted mankind more than any other simulator.

That's why LTspice IV is fast.But all this is for a purpose.

This self-authoring code is generated typically every few seconds during the simulationto help your circuit execute close to the theoretical flop limit of a modern CPU. Then that code is assembledand linked by LTspice for execution. Another important technique introduced at thattime was code generation that generates an assembly listing optimized for your circuit. That's when we developed a means to dynamically adjust each threads' cache sizeto stochastic cool the threads to keep the work load spread evenly. The problem was thatthe LTspice object code had been so optimized (much had already been implemented in optimized assembly language)that it didn't take very many microseconds per timestep and that was a short time compared to how well onecan synchronize multiple threads. We found it easy to distribute thecomputations over multiple cores but challenging to make the simulation actually run faster. It let me implement a number of numerical methods that make LTspice better thantraditionalSPICE programs: a new numerical integration method, node reduction, a native circuit element that behaveslike a power MOSFET, and new time step size control to name a few.The biggest recent advance in LTspice was when it went multi-threaded in 2008. I appreciate his work writing this book and hope you benefit fromhis labors.LTspice has been fun to write.

It is an honor to write a preface for Gilles Brocard.
