The text that describes intrinsic SPICE models can be placed directly on an LTspice schematic by using the spice directive .op button. [18] The advantage of this method is the 3rd party model is self-contained as part of the schematic when you distribute the schematic file.
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
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.
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.
Following approaches for adding user-defined models are supported: Behavioral voltage and current sources (B devices) XSPICE code models written in C; Verilog-A models that can be compiled with OpenVAF compiler; SPICE OPUS supports parameterized netlists, parameterized subcircuits, and topology changes without simulator restart (netclass).
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] Mixed-mode simulation is handled on three levels: with primitive digital elements that use timing models and the built-in 12 or 16 state digital logic ...
Multisim includes microcontroller simulation (formerly known as MultiMCU), [3] as well as integrated import and export features to the printed circuit board layout software in the suite, NI Ultiboard. [4] Multisim is widely used in academia and industry for circuits education, electronic schematic design and SPICE simulation. [5]
Because the event-driven algorithm is faster than the standard SPICE matrix, simulation time is greatly reduced for circuits that use event-driven models in place of analog models. Mixed-mode simulation is handled on three levels by CircuitLogix: (a) with primitive digital elements that use timing models and a built-in 12-state digital logic ...
