SPICE
3F5 Simulation Engine: Powerful & Reliable
B2 Spice is derived from the industry standard simulation program,
SPICE 3F5 which was developed at the University of California, Berkeley.
B2 Spice includes a host of new devices including lossless transmission
lines, lossy transmission lines, current and voltage controlled
switches, arbitrary sources, MESFETs, and uniform RC models.
Available
Analysis
With SPICE 3F5 as the "engine" to drive the simulation,
B2 Spice is capable of providing a variety of standard analysis
including DC, AC, transient, Fourier, noise, sensitivity, distortion,
and small signal transfer function.
Berkeley
SPICE Models
Detailed
Simulation Control
Full access to Berkeley SPICE simulation control options is provided.
For example, tolerances for transient convergence, set global defaults
for transistor channel lengths and widths, and much more.
Device
Model Library
Berkeley
SPICE Model Library
B2 Spice algorithms provide accurate and flexible modeling of semiconductor
devices, passive elements, and ideal switch components. The following
B2 Spice models and features in the analog library are in addition
to the standard models and features. These include MOSFETs, GaAs
MESFETs, Resistors, capacitors, inductor models, Lossy transmission
lines, Coupled transmission lines, Voltage and current-controlled
switches.
Commercial
Analog Model Library
Hundreds of common discrete devices are available in B2 Spice analog
model library. These discrete devices include: bipolar junction
transistors, Zener diodes, Schottky diodes, power MOSFETs, voltage
regulators, operational amplifiers, opto-couplers, voltage comparators,
voltage references, and switching-matrix connectors. Our offerings
include over 3000 models created by such industry
leaders as AMP, APEX, Burr-Brown, Comlinear Corporation, Elantec,
Linear Technology, Maxim, Motorola and many more.
Versatile
Modeling Capabilities
B2 Spice offers numerous ways to model the behavior of circuit components
including simple redefinition of model parameters and creation of
new device models and subcircuits.
Simulation
Results Display
Graphical
Waveform Analysis
Simulation results can be selectively displayed and analyzed after
having paused or completed the simulation. B2 Spice's display capabilities
are completely flexible allowing you to configure any number of
plots, X and Y axes, and analog traces (i .e. waveforms) within
the display area, as well as linear/log scales. You can also log
sessions and print hard copies of the current display. You can display
waveform results as they are generated. Also, cross probing allows
you to select pins, wires, and devices within your schematic for
automatic display of waveforms in the graph.
Cross
Probing
Cross probing allows you to display waveform results by simply marking
pins, wires, and devices on the circuit drawing. Monitor results
while simulation in progress, then plot the results for linear or
log-log scales.
Stimulus
for Simulation
Sinusoidal, constant, periodic pulse, exponential, single frequency
FM, and piecewise linear waveforms are available as the building
blocks for stimulus waveforms.
Graphs
Analog traces may be displayed as raw voltages and current values,
or further processed using arithmetic expressions, functions (e.g.,
derivatives, integrals, group delays, and RMS average), and Fast
Fourier Transforms.
View actual plot values corresponding to the cursor position on
the graph.
Schematic
Editor
Whether your task is to create stand-alone circuit diagrams, or
to prepare designs for simulation, B2 Spice's Windows-driven schematic
capture of B2 Spice provides you with an efficient development environment
for defining modular circuit designs. B2 Spice comes complete with
symbol and package libraries containing over a thousand analog parts
and integrated symbol editing.
Invocation of stimulus and model editing is as simple as selecting
the appropriate part symbol on your schematic. Dialogs within B2
Spice allow you to enable and set up analyses, and run simulations.
Cross probing allows you to select pins, wires, and de vices within
your schematic to automatically display waveforms in the graph.
The full featured schematic editor complete with "rubberbanding",
auto-scrolling, zoom, copy/paste/undo, and rotation/flipping of
parts.

Model
Editor
B2 Spice includes an editor to investigate or alter any of the SPICE
models or to create your own. You have complete control over all
parameters of the built-in Spice models. In addition, you can directly
edit the text of subcircuit based models. Use the library editor
to develop libraries of customized parts that meet your own specific
needs.
Models
of Third Party Parts
Parts may be imported from third parties by choosing the Import
Library feature from B2 Spice's library editor module.
