New VisSim Version 8

VisSim State Charts addon
There’s a brand new version of VisSim, the dynamic systems simulation software with an easy-to-use block diagram interface – and new VisSim 9 is at the heart of the latest VisSim/Embedded Controls Developer (VisSim/ECD), the ideal tool for developing embedded control systems based on Texas Instruments processors.

Supporting a wide range of TI DSPs including MSP430, C2000, Piccolo and Delfino, VisSim/ECD makes it quick and easy to create, optimise and debug a working model of your control system and, when you’re happy with its performance, generate highly efficient C-code at a click.

VisSim version 8 expands tool chain with new UML graphical state chart module

The next generation of VisSim from Visual Solutions Incorporated (VSI) (Westford, Massachusetts) is now available from Adept Scientific (Letchworth, Herts).  VisSim version 8 is the much anticipated product upgrade and introduces exciting new concepts including VisSim/State Charts, a new UML graphical state chart editor, as well as many other product enhancements.

The introduction of VisSim/State Charts to VisSim version 8 allows you to create, edit, simulate and generate embedded C code for state charts all within the standard VisSim environment. VisSim/State Charts provide:

• OMG UML 2.1 Compliance
• Simple, composite and submachine states
• Animation of transition state
• Nested states
• Parallel states
• Single step simulation
• Suspended and resumed states
• Entry, exit, transition and “DO” actions using C syntax
• Breakpoints for selected events
• Logging of selected events and executed behavioural C code
• ANSI C code generation.

“Our goal at Visual Solutions is to help companies bring innovative and complex products to market as quickly and efficiently as possible,” said Visual Solutions CEO, Peter Darnell. “The new state chart module makes it easier than ever for engineers and scientists to design embedded systems that contain supervisory and high-level control logic.”

“We’ve been using a pre-release version of VisSim/State Charts and have seen bottom line benefits in our development cycle from day one,” said Mike Borrello, Systems Engineering Manager at Luminous Medical. “We’re currently using VisSim version 8 to design and test a new state machine for our glucose monitor. I was amazed at what a difference it made to use the new state chart editor. In only two weeks, we took our design from concept to a fully functioning system with hardware-in-the-loop. Without state charts, we wouldn’t have been able to effectively meet our deadline.”

VisSim version 8 provides more visually intensive and customisable, real-time gauges which can be connected to rapidly changing data sources. The new gauges incorporate features like dial colour, transparency and reflection to allow increased visibility and impact in your models. In addition, major and minor tick values, labels and an editable sweep angle give you the flexibility to create more realistic dashboard and control panel gauges.

Enhanced data set handling

• Import and map blocks take text column headers in a data file and automatically put the column header on the corresponding output pin for the block. For large multi-column data sets, this greatly enhances readability.
• Data export blocks support macro expansion in the header comment. This allows insertion of date and time, along with path and variable values into the header text of a data file.
• Data export blocks have an auto email option for emailing zipped data sets to user-specified recipients. This allows remote monitoring and reporting.
• Support of standard bitmap formats (.png, .gif, .jpg) for buttons and animations.
• Enhanced parsing of foreign data sets.

New Real-Time Devices

• UDP packet exchange add-on to give fast Ethernet based data exchange over intranet or internet.

VisSim™ Embedded Controls Developer supports TI C2834x Digital Signal Controllers

Visual Solutions Incorporated’s (VSI) (Westford, Massachusetts) VisSim/ECD Version 7.0 with support for Texas Instruments’ (TI) TMS320C2834x “Delfino” floating-point digital signal controllers (DSCs) is now available from Adept Scientific (Letchworth, Herts).

Providing 600 million floating point instructions per second (MFLOPS) performance at 300 MHz, the C2834x devices bring higher performance and simpler software development to embedded applications such as industrial control, medical devices, digital power conversion and advanced sensing. Version 7.0 of VisSim/ECD adds support for the C2834x series to its existing support of all previous F28xx controllers.

VisSim/ECD allows developers to program the C2834x DSC without writing a single line of code by easily constructing block diagrams to form DSC algorithms. With blocks to support standard maths and signal processing operations, as well as all of the on-chip peripherals of the C2834x controllers, programming for TI DSCs is now easier than ever.

The ability to simulate algorithms on the PC allows offline troubleshooting and optimisation, shortening development time by a factor of 2 or more and removing the need for a dedicated programmer. VisSim/ECD’s advanced code generator results in faster sampling rates and low RAM usage comparable to hand-coded assembly.

“VisSim/ECD provides designers with the ability to develop an entire application based upon the C2834x controllers working only at the block diagram level while utilising the full performance of the C283xx,” said Andrew Soukup, C2000 Worldwide Marketing Manager for TI. “With this new offering, VSI allows any developer, even those without prior DSC experience, to quickly bring new products to market.”

VisSim/ECD v7.0 adds support for the increased RAM and clock speed as well as the additional CAP, SPI and floating point unit on the new C2834x controller series from TI. In addition, VisSim/ECD v7.0 adds general programming features such as:

  • Automatic peripheral programming
  • Easy selection of interrupts for graphical interrupt handler creation
  • Stack and heap probe
  • Check box enabled background thread scheduling
  • State machine driven serial protocol handling
  • Control sampling rates over 1MHz on C2834x parts
  • Interrupt driven serial queue for SCI, I2C and SPI with user selectable queue length up to 255 bytes
  • Low memory footprint uses as little as 750 words flash, 80 words RAM for PID control of a quadrature encoder sensed, PWM actuated closed loop control application

VisSim/ECD’s advanced feature set makes C and assembler programming a thing of the past. Systems designers who are unfamiliar with TI’s DSCs or hand coding can now take advantage of the simpler software development provided by the C2834x controllers, resulting in eliminating weeks – even months – of development time.

Dr Ziaur Rahman, Director of Electrical Controls at Electric Motion Systems, is using VisSim/ECD 7.0 to develop PMSM electric motor control using the TMS320F2801 controller from TI. According to Dr Rahman, “VisSim/ECD is an essential tool for us in developing vector motor controls for electric bicycles. Code development time is greatly reduced with VisSim/ECD’s ready-to-use block sets and efficient debugging capability.”

Visual Solutions brings you sleep solutions

Adept Scientific plc (Letchworth, Herts): Visual Solutions (Westford, Massachusetts) is working with ResMed (Sydney, Australia) to bring an end to sleep-disordered breathing (SDB) and other respiratory disorders.

Clinical trials on patients are a slow and expensive process with zero repeatability so it makes sense to simulate the symptoms experienced.  This is where VisSim is enabling ResMed to a quicker result.

By using VisSim to develop a ‘bench patient’, ResMed has been able to develop its own breathing simulators based on sophisticated physiological computer models, together with a library of VisSim-based ‘virtual patients’ with a variety of pathologies.

The VisSim based ‘bench patient’ has greatly accelerated equivalence testing of ResMed’s second-generation therapy device.  The result was shorter clinical trials and reduced time-to-market.

ResMed sees its continuing use of VisSim as beneficial in simultaneously maximising quality, minimising development time and enhancing the customer experience through use of realistic product models.

VisSim 7 is launched

February 2008: Adept Scientific (Letchworth, Herts) is pleased to announce the launch of VisSim 7 from Visual Solutions Inc (Westford, MA). Delivering unmatched power, flexibility and extensibility, VisSim 7 is the latest version of the award-winning, Windows-based program for the modelling and simulation of complex nonlinear dynamic systems. It combines an intuitive drag and drop block diagram interface with a powerful simulation engine, making it the fastest and easiest-to-use simulation and embedded system design software available.

VisSim 7 is packed with new features which make VisSim even more powerful, flexible and intuitive to use. Engineers will now gain a better physical understanding of model behaviour through 3D plots and animations as well as better simulating the noise in real-world systems with new random number routines.

The developers have committed to capturing the attention of a wider audience with vastly enhanced matrix functionality. A high-level language enables modellers to manipulate matrices and rapidly construct them with a spreadsheet-type table (into which data from Excel and Mathcad can be pasted). Other highlights include the ability to solve systems of linear equations (including over- and under-determined systems), calculate eigenvalues/eigenvectors and realistically interpolate physical data through polynomial and spline fits.

Visual Solutions have also delivered better usability than ever. Engineers can better integrate simulations into printed reports with an optional blue margin to show the printable part of the model and the facility to print only what you see on screen. They will also get working faster with a new option to automatically reload the last saved model.

VisSim 7 impresses at the VisSim European User Meeting

VisSimEuropean simulation enthusiasts previewed VisSim 7, the latest release of the leading simulation software tool, at the headquarters of Adept Scientific (Letchworth, UK) last week. The two day event was delivered by Pete Darnell, CEO and Chief Software Engineer at developers Visual Solutions Inc (Westford, MA).

The first day concentrated on the new features in VisSim 7, including 3D animation, 3D plotting, a vastly increased range of matrix operations, auto save and printing improvements. Delegates were particularly impressed by the ease of 3D animation and new spreadsheet-like interface for specifying tabular data and new routines for smoothly interpolating physical data. The following day focussed on a hands-on training course in Visual Solutions’ Embedded Controls Development (ECD) software environment. Delegates learned how to develop algorithms using ECD and downloaded them to F2812 DSPs – motivated by the opportunity to win a DSP. All delegates took home a TI MSP430 low power microprocessor evaluation kit as a thank you for attending.

Alan Riley, an engineer from Sensonics who attended the User Meeting, said: “I got exactly want I wanted from the course; on the first day a very good introduction to VisSim from someone who has a deep understanding of the software. The second day demonstrated the power and simplicity of VisSim ECD in DSP applications; this has to be the way to go for DSP development”.

Pete Darnell was particularly impressed by the calibre of the delegates and remarked: “Our European users continue to impress me with their creativity and knowledge level. I think they use VisSim to add greater intellectual value to product development than users elsewhere. It is rewarding to see such deep appreciation of VisSim. It’s a major impetus for spurring my desire to deliver highly accessible model based development tools that reduce development time, increase product quality and continue to offer the fastest simulation speed and most efficient code generation on the market today”.

He plans to return in mid 2008 and repeat the event as a part of Visual Solutions’ commitment to remain close to its European user-base. Simulation experts and new users can register an initial interest in attending by emailing info@alfasoft.com.

VisSim is a Windows-based program for the modelling and simulation of complex nonlinear dynamic systems, combining an intuitive drag-and-drop block diagram interface with a powerful simulation engine. VisSim 7 is scheduled for release in early 2008.

New Version 6.0 of VisSim is now shipping

Adept Scientific is pleased to announce the release of VisSim Version 6.0 for Windows 95/98/2000/NT/XP from Visual Solutions Incorporated (VSI). VisSim 6.0 is the latest version of the award-winning, Windows-based program for the modelling and simulation of complex nonlinear dynamic systems. It combines an intuitive drag and drop block diagram interface with a powerful simulation engine, making it the fastest and easiest-to-use simulation and embedded system design software available.

VisSim Version 6.0 adds new blocks, an improved simulation engine, and enhanced user interface. The new blocks read and write audio from .WAV files or a Windows audio device enable the user to control the delay for the ‘on’ and ‘off’ commands found in process control. Other new blocks identify the location and value of the minimum and maximum elements of a matrix, give the time of day, and display a coloured bit for every element in a matrix.

The new Maple interface blocks communicate with Maple mathematical problem-solving software. These blocks allow the reading and writing of scalar and matrix data to the Maple workspace, as well as execution of Maple scripts. This brings a fast smooth interface between VisSim and Maple.

The new add-on ‘Knobs and Gauges’ block set lets the user specify various blocks to give high quality graphical behaviour of interactive gauges, meters, dials, switches and knobs. This allows the user to create a ‘dashboard’ face plate to drive and monitor your VisSim model.

VisSim 6.0 brings an improved user interface. The addition of the VisSim Tutor allows the user to annotate a VisSim diagram with interactive help balloons so that the user can read and understand it better.

The new VisSim Diagram Explorer Window now allows the user to explore the VisSim menu hierarchy. This makes it very convenient to insert blocks from deeply nested menu trees.

Simulation engine enhancements include:

  • Subsystem Superclocking, which allows all blocks within a compound block to run at a user defined rate faster than the overall sym rate. It allows for containment of high frequency components, iterating through matrices, or modelling of partial differential equations.
  • Two new adaptive integration methods for solving stiff systems.
  • A real time scale factor which allows the user to run real time simulations at multiples or fractions of real time.
  • Auto check pointing lets the user automatically save diagram state to a file name with a time stamp suffix. The file contains the current state of all variables in the diagram at that point of the simulation. This is useful for operator training, allowing the operator to go back in time and re-simulate questionable decisions.

VisSim 6.0 is supplied and supported in the UK and Ireland by Adept Scientific plc, Amor Way, Letchworth, Herts. SG6 1ZA; telephone +44 (0) 203 695 7810, fax +44 (0) 203 695 7819, e-mail info@alfasoft.com; or see Adept’s dedicated World Wide Web site http://www.adeptscience.co.uk/.
