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.
For example, 2MegHz, or 2MegaOhm represents 2000000; 3mV, or 3mOhm represents 0.003; 4uF, or 4uHenry represents 0.000004. In LTspice, any suffix (left column) can replace the decimal point of a real number, a common format for printed schematics. [26] [17] For example, 4K7 represents 4700, 1u8 represents 0.0000018.
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.
NI Multisim (formerly MultiSIM) is an electronic schematic capture and simulation program which is part of a suite of circuit design programs, [1] along with NI Ultiboard. ...
Ngspice is based on three open-source free-software packages: Spice3f5, Xspice and Cider1b1: SPICE [ 5 ] is the origin of most modern electronic circuit simulators, its successors are widely used in the electronics community.
Of these, LTSpice and Micro-cap are free proprietary applications based on SPICE. Micro-Cap was released as freeware in July 2019, when its parent company Spectrum Software closed down while LTSpice has been free for a long time.
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
In semiconductor manufacturing, a process corner is an example of a design-of-experiments (DoE) technique that refers to a variation of fabrication parameters used in applying an integrated circuit design to a semiconductor wafer. Process corners represent the extremes of these parameter variations within which a circuit that has been etched ...
