Spectre is a SPICE-class circuit simulator owned and distributed by the software company Cadence Design Systems.It provides the basic SPICE analyses and component models. It also supports the Verilog-A modeling langua
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]
When more accuracy is desired in modelling the diode's turn-on characteristic, the model can be enhanced by doubling-up the standard PWL-model. This model uses two piecewise-linear diodes in parallel, as a way to model a single diode more accurately. PWL Diode model with 2 branches. The top branch has a lower forward-voltage and a higher ...
The Gummel–Poon model and modern variants of it are widely used in popular circuit simulators such as SPICE. A significant effect that the Gummel–Poon model accounts for is the variation of the transistor β F {\displaystyle \beta _{\text{F}}} and β R {\displaystyle \beta _{\text{R}}} values with the direct current level.
Semiconductor device modeling creates models for the behavior of the electrical devices based on fundamental physics, such as the doping profiles of the devices. It may also include the creation of compact models (such as the well known SPICE transistor models), which try to capture the electrical behavior of such devices but do not generally ...
SPICE simulates IGBTs using a macromodel that combines an ensemble of components like FETs and BJTs in a Darlington configuration. [citation needed] An alternative physics-based model is the Hefner model, introduced by Allen Hefner of the National Institute of Standards and Technology. Hefner's model is fairly complex but has shown good results.
SmartSpice is a commercial version of SPICE (Simulation Program with Integrated Circuit Emphasis) developed by Silvaco.SmartSpice is used to design complex analog circuits, analyze critical nets, characterize cell libraries, and verify analog mixed-signal designs.
MOSFET and Diode Level 2 models were added in the version 10 release. These models allow the simulation of the switch transition, reverse recovery effects, and gate drive circuitry. [ 12 ] A comparison with a PSIM & SPICE model of the same device showed similar resulting waveforms with a comparable simulation speed given identical operating ...
