Modelling, Simulation & Control System Design
VisSim is an award winning software
program for the modeling and simulation of complex dynamic systems. VisSim combines an intuitive drag & drop block diagram interface
with a powerful simulation engine. The visual block diagram
interface offers a simple method for constructing, modifying and
maintaining complex system models. The simulation engine provides
fast and accurate solutions for linear, nonlinear, continuous time,
discrete time, time varying and hybrid system designs.
Signal Processing & communication System Design
VisSim /Comm is the fastest and easiest-to-use software for
the modeling and simulation of physical layer end-to-end
communication systems.
DSP & Embedded System Design
VisSim / DSP combines a powerful code
generator with runtime target support for rapid prototyping of
control, communication or signal processing algorithms for
DSPs and embedded systems.
General description
With VisSim, users can
quickly develop software or "virtual" prototypes of systems or processes
to demonstrate their behavior prior to building physical prototypes.
Built-in integration tools allow users to communicate seamlessly with
MATLAB and
Mathcad. A
VisSim/SIMULINK
Translator allows SIMULINK users to import SIMULINK V2 or V3
block diagrams directly into VisSim.
The user builds his system model by
selecting predefined blocks from a block library and simply wiring
(graphically connecting) the blocks into a diagram. Each block of
the diagram performs a mathematical or input/output function. These
"blocks" may represent complex algorithms, input variables, or
various outputs like graphs, charts, plots or data files. Users can
also create custom blocks in C, Fortran or Pascal and add them to
the VisSim block library. After the model is configured, a
simulation is run and results of the simulation are
displayed.
Once the behavior
of the system model is understood, often the next step is to develop
a "software" controller that will control the behavior of the model
and eventually the physical system itself. In the above example, a
motion control engineer developed a system model of an AC Induction
Motor and then developed a "software" PID controller to control the
torque, velocity and position of the motor.
The core product,
VisSim,
is used for general modeling, simulation and control system design
applications. VisSim product options include
VisSim/Analyze,
for frequency domain analysis, and
VisSim/Real-Time,
for real-time hardware-in-the-loop validation.
The addition of a comprehensive library of
communication blocks to the core VisSim product results in a product
called
VisSim/Comm
- an integrated solution for the modeling and simulation of analog,
digital or mixed-mode, end-to-end communication systems. Pre-built
blocks like signal sources, encoders/decoders,
modulators/demodulators, filters, channels, RF components and PLLs
make it easy to build, maintain and modify even the most complex
communication system models.
VisSim/SigPro
is an integrated solution for the rapid prototyping of signal
processing algorithms or systems. It is a sub-set of the VisSim/Comm
product. The VisSim/SigPro block library includes pre-built blocks
like signal sources, filters, estimators, digital elements,
operators and basic modulator/demodulator blocks.
The
VisSim/C-Code
product option is available for VisSim, VisSim/Comm
and VisSim/SigPro. VisSim/C-Code automatically generates ANSI
C code for the model/controller/algorithm. The C code can be
compiled and run on any platform that supports an ANSI C
compiler.
Finally, integrated
VisSim/DSP
solutions enable users to model and simulate their
control/communication/signal processing system, automatically
convert their algorithm to ANSI C code and compile-link-download the
system/algorithm to a DSP/embedded system.
