Mathcad INTEGRATION

VisSimforMathcad 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!

MATLAB INTEGRATION

VisSimforMathcad offers several easy-to-

use features for integrating MATLAB files,

variables or functions within the VisSim

simulation environment.

I MATLABFile Import: Standard

VisSim transferFunction and stateSpace

blocks can be easily configured to

import MATLAB .m or .MAT files that

represent SISO (single-input single-

output) state-space representations

I MATLABReadand MATLABWrite

Blocks: VisSim includes MatlabRead

and MatlabWrite blocks that enable

variables to be dynamically exchanged

between MATLAB and VisSim

MATLABExpression Block: VisSim also

includes a MATLAB Expression Block that

enables MATLAB scripts to be edited and

executed directly from the VisSim

environment.

VisSim VIEWER

VisSimforMathcad includes the unique

VisSimViewer a run-time, view-only

version of VisSim that enables users to

distribute models to individuals not licensed

to use VisSim.

The Viewer is a great way to share models

and simulation results with colleagues,

suppliers and partners. Recipients of the

Viewer can run simulations, change block

and simulation parameters (e.g., optimize

gains) and perform interactive what-if

scenarios.

Modelling & SimulationSoftware for Mathcad

I Easy-to-useI No programming required - OLE

compliant integration with MathcadI Based on proven, award-winning VisSim

technologyI Affordable

VisSim for Mathcad brings engineers worldwide an intuitive

drag-and-drop interface to model and simulate a vast array of

dynamic systems. VisSim for Mathcad allows Mathcad users

to create virtual software prototypes on their desktops,

saving design time and costs associated with physicallybuilding and testing models.

GENERAL MODELLING,SIMULATION ANDCONTROL SYSTEM DESIGN

VisSim for Mathcad includes over 110 general blocks including

Linear (e.g. state space and transfer function) and Nonlinear

System blocks, Integration, Optimisation, 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.

VisSim for Mathcad features an intuitive

drag-and-drop block diagram interface and a

powerful simulation engine. VisSims proven

block diagram interface offers the easiest

method you can find for constructing,

modifying, optimising, validating and

maintaining complex system models. Users can

select from over 200 pre-configured blocks and

wire them together using point-and-clickcommands.The time-domain simulation engine

provides fast and accurate solutions for linear,

nonlinear, continuous time, discrete time, time

varying and hybrid system designs.

Example of a signal processing application using a Fouriertransform and a wavelet transform with a VisSim for

Mathcad model

This diagram illustrates the use of baseband equalisation

to compensate for channel distortions on a 16 QAM link. A

modulated signal is distorted via a band-limited, low pass

Chebyshev filter, and the effects of the filter are evident by

looking at the eye plot and phase scatter plot. A 5 tap

adaptive equaliser is used to compensate for the filter

distortions and the output of the equaliser is shown for

comparison. By looking at the simulation over three cycles,

the adaptation process is illustrated. The point at which

the equaliser forces the eye open is controlled by theclock delay adjustment setting. The relative amplitude of

the incoming waveform can also be modified using the

gain adjustment.

With VisSim for Mathcad, Visual Solutions has created apowerful tool that significantly expands my capabilities fordesign work. VisSim for Mathcad provides me an affordableand easy way to implement dynamic equations in eithercontinuous or discrete time. I can now use Mathcad andMathcad Extension Packs like the Sig nal Processing Packtogether with the modelling and simulation power of VisSim -all in an i ntegrated environment.

ANALOG, DIGITAL & MIXED-MODECOMMUNICATION SYSTEM DESIGN

VisSim for Mathcad includes over 40 communication blocks

for the modelling 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

VisSimforMathcadalso 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.
