VisSim is a block diagram language for creating complex nonlinear
dynamic systems. To create a model, simply drag blocks in the workspace
and connect them with wires. Then click the Go button to initiate
your simulation. The response is instantaneous. You can choose to
display your response in 2D or 3D plots, gauges, bar charts, meters,
digital readouts, and even 3D animated scenes. All are driven in
real time using the VisSim engine.
VisSim's highly tuned math engine executes your diagram directly
with no compilation delay. In addition to accelerating development
with rapid turnaround for changes, VisSim's fast execution speed
is perfect for model based operator training, off-line controller
tuning, and hardware-in-the-loop testing. Its efficient C code generator
makes it an ideal platform for model-based embedded system development.
By combining the simplicity and clarity of a block diagram interface
with a high-performance mathematical engine, VisSim provides fast
and accurate solutions for linear, nonlinear, continuous time, discrete
time, SISO, MIMO, multi-rate, and hybrid systems. With VisSim's wide
selection of block operations and expression handling, complex systems
can be quickly entered into VisSim.

VisSim's tightly integrated development platform makes it easy to
pass freely among the stages of model construction, simulation, optimization,
and validation. This means you can create virtual prototypes on your
desktop and make sure they're working properly before committing
to the design. And because VisSim eliminates traditional programming,
your learning time is minimal.
VisSim has libraries of preconstructed components giving you access
to high level models of subsystems like HVAC units, AC and DC electric
motors, hydraulic components, gas turbines, human respiration and
blood flow, 6-DOF airframe dynamics, counters, timers, logic, and
much more. Just right click to get a dialog box, configure to your
system parameters, connect the wires and go.
New 7.0 features add interactive 3D plotting and 3D animation as
shown above.
For specialized engineering problems, VisSim offers a comprehensive
set of companion products for frequency domain analysis, C code generation,
communications system modeling, DSP and embedded system design, neural
networks, OPC, CAN, and real-time analog and digital I/O. These addon
modules are listed in the Products sidebar.
With over 100 thousand users across a broad range of industries
and disciplines, VisSim is a world leader in dynamic simulation software
and model-based development.
