LTspice features that may not be supported by some SPICE programs: Unicode characters in schematics, netlists, plot. [6] This is a new feature in LTspice XVII, thus older versions of LTspice don't support Unicode. [6] Unicode (U+00B5) µ micro character as an alternate symbol for ASCII (hex 75) u letter, which used as the micro (10 −6) scale ...
2008 – LTspice IV released. [2] It ran on Windows 2K, XP, Vista, 7. A native macOS 10.7+ application was introduced in 2013. 2016 – LTspice XVII released. [2] It ran on 32 or 64-bit Windows 7, 8, 8.1, 10; and macOS 10.9+. 2023 – QSPICE beta released. [4] Initially, it is designed to run on Windows 10 and 11.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
The world of electronic design automation (EDA) software for integrated circuit (IC) design is dominated by the three vendors Synopsys, Cadence Design Systems and Siemens EDA (Formerly Mentor Graphics, acquired in 2017 by Siemens) which have a revenue respectively of 4,2 billion US$, 3 billion US$ and 1,3 billion US$.
Ngspice supports parametric netlists (i.e. netlists can contain parameters and expressions). PSPICE compatible parametric macromodels, often released by manufacturers, can be imported as-is into the simulator.
An LTSpice simulation of the non-linearized VCR design verifies that the JFET resistance changes with a change in gate-to-source voltage (V GS). In the simulation (below), a constant input voltage is applied (the VDC supply is set to 4 volts), and the gate-to-source voltage is reduced in steps, which increases the JFET drain-to-source resistance.
EasyEDA is a web-based electronic design automation (EDA) tool suite that enables hardware engineers to design, simulate, share (publicly and privately) and discuss schematics, simulations and printed circuit boards, and to create a bill of materials, Gerber files, pick and place files and documentary outputs in the file formats PDF, PNG, and SVG.
rotating electric machines [17] power transformers [18] magnetostrictive actuators [19] magnetoelastic sensors [20] [21] magnetic field sensors (e. g. fluxgates) [22] [23] It is also widely used for electronic circuit simulation, especially for models of inductive components, such as transformers or chokes.
