The following table is split into two groups based on whether it has a graphical visual interface or not. The latter requires a separate program to provide that feature, such as Qucs-S, [1] Oregano, [2] or a schematic design application that supports external simulators, such as KiCad or gEDA.
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$.
LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology). [2] It is the most widely distributed and used SPICE software in the industry. [ 6 ]
PSPICE compatible parametric macromodels, often released by manufacturers, can be imported as-is into the simulator. Polynomial sources are available. Polynomial sources are available. Ngspice provides an internal scripting language to facilitate complex simulation and evaluation control flows.
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. ...
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.
It was developed by Spectrum Software, and was only available with a paid commercial license. [2] In July 2019, Spectrum Software closed down and Micro-Cap was released as freeware. [3] Software updates and technical support are no longer available. In early 2023, their website went offline, though it was previously backed up at archive.org. [4]
Schematic of Spice Gummel–Poon model NPN. The Gummel–Poon model is a model of the bipolar junction transistor.It was first described in an article published by Hermann Gummel and H. C. Poon at Bell Labs in 1970.
