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
The advantage of this method is the 3rd party model is self-contained as part of the schematic when you distribute the schematic file. The same .model can also be copied to an ASCII text file on your computer too, [19] but it won't "travel" with a schematic when you copy it to another computer. For example, the following diode part numbers aren ...
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.
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 ...
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 ...
For example, elements can use real or integer values to simulate DSP functions or sampled data filters. Because the event-driven algorithm is faster than the standard SPICE matrix solution, simulation time is greatly reduced for circuits that use event-driven models in place of analog models. [5]
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.
SPICE [5] is the origin of most modern electronic circuit simulators, its successors are widely used in the electronics community. Xspice [6] is an extension to Spice3 that provides additional C language code models to support analog behavioral modeling and co-simulation of digital components through a fast event-driven algorithm.
