PATRUCCO - VisSim: VisSim for Mathcad

"With VisSim for Mathcad, Visual Solutions has created a powerful tool that significantly expands my capabilities for design work. VisSim for Mathcad provides me an affordable and easy way to implement dynamic equations in either continuous or discrete time. I can now use Mathcad and Mathcad Extension Packs like the Signal Processing Pack together with the modeling and simulation power of VisSim - all in an integrated environment."

-- Mike Borrello, Senior Systems Engineer, Trex Enterprises, San Diego, CA

VisSim for Mathcad features an intuitive drag-and-drop block diagram interface and a powerful simulation engine. VisSim's proven block diagram interface offers the easiest method you can find for constructing, modifying, validating and maintaining complex system models. Users can select from over 200 pre-configured blocks and wire them together using point-and-click commands. The time-domain simulation engine provides fast and accurate solutions for linear, nonlinear, continuous time, discrete time, time varying and hybrid system designs.

GENERAL MODELLING, SIMULATION AND CONTROL SYSTEM DESIGN
VisSim for Mathcad includes over 110 general blocks including Linear (e.g., state space and transfer function) and Nonlinear System blocks, Integration, Optimization, Matrix Operation, Arithmetic, Signal Consumer and Signal Producer blocks. A Controls Toolbox Library that includes pre-built P, PI, PID controllers, rate feedback and limited controllers makes VisSim for Mathcad ideal for control system design applications.

ANALOG, DIGITAL & MIXED-MODE COMMUNICATION SYSTEM DESIGN
VisSim for Mathcad includes over 40 communication blocks for the modeling and simulation of analog, digital and mixed-mode end-to-end communication systems at the signal or physical level. The communication block set includes encoders and decoders, modulators and demodulators, channels, RF components and PLLs.

SIGNAL PROCESSING
VisSim for Mathcad also includes over 55 proven signal processing blocks including signal sources (e.g., Waveform Generator, Sinusoid, Frequency Sweep), filters (e.g., Adaptive Equalizer, File FIR, FIR, IIR), operators (e.g., A/D Converter, Complex FFT, IFFT, PSD, Spectrum Analyzer), estimators and digital elements that make it easy to model and simulate complex signal processing algorithms. It also includes a built-in FIR and IIR filter design wizard and filter response viewer to simplify and automate the filter design process.

MATHCAD INTEGRATION
VisSim for Mathcad includes OLE/COM compliant integration with Mathcad 2000 and 2001.This integration provides Mathcad users with a simple and seamless method for performing dynamic system simulations. Mathcad users can create new, or embed existing Mathcad documents within a VisSim model by using the Mathcad_OLE block. Users can dynamically exchange scalar or matrix data between VisSim and Mathcad using the simple VisSim click and wire interface -no programming required!

VisSim for Mathcad also includes:

Easy-to-use features for integrating MATLAB files, variables or functions within the VisSim simulation environment
The unique VisSim Viewer - a run-time, view-only version of VisSim that enables users to distribute models to individuals not licensed to use VisSim
