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.

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.
