Island Logix Ships VisualSPICE Design Studio Advanced Version 6 Analog, Digital, Mixed Signal Simulator Sporting 95% of the Features of Expensive SPICE Simulators at a Tiny Fraction of the Price - A Complete Electronics Lab in One Program

VisualSpice Advance is the First SPICE Simulator to give users the ability to develop and "Plug-In" new device model primitives into the simulator dynamically.

Island Logix Inc. today announced its next generation analog, digital, mixed signal simulator VisualSpice Advance version 6, giving users 95% of the features of more expensive SPICE simulators at only a tiny fraction of the price. With it's three built in integrated seamless native mode simulation engines, it is a complete electronics lab in one program that includes several built-in virtual instruments allowing users to take readings directly off their live schematic, such as a 64-channel scope, spectrum Analyzer, multi-channel logic analyzer, Frequency Counter, multi-meter etc.

It offers the advanced feature of allowing users and third party developers the ability to develop their own device model primitives using Microsoft Visual C++ and SPICE3F5/XSPICE-HDL that "plug-in" to the simulator dynamically.

XSPICE-HDL is an industry standard Hardware Description Language developed at Georgia Tech Research Institute. Users can develop complex devices and models from scratch using Microsoft Visual C or C++ and XSPICE-HDL, rather than use the standard SPICE built-in model primitives and macro models to fashion a new device.

Using standard built in SPICE device primitives for modeling provides only a very slow approximate model due to the fixed characteristics of the built in primitives of a standard SPICE simulator and the large number of primitives required. The new Plug-in feature greatly increase simulation speed and accuracy since devices are modeled at the C/C++ programming level rather than using macro models and built in device primitives. Entire system at the board level can be simulated. Source level debugging, single stepping, breakpoints and testing can be performed on a virtual embedded program running on the virtual MCU running on a virtual circuit schematic. Entire systems can be debugged and tested before they are built.

XSPICE-HDL language extensions allow plug-in devices to output text and graphics directly to the schematic allowing for interactive devices that can display results and status right in the schematic during simulation. Plug-in device models can be analog, digital, or a mix of both. Models can be almost anything such as switching regulators, LCD displays, test instruments (scopes or spectrum analyzers), or for automated testing similar to the popular LabView. Entire systems can be placed on the schematic and simulated from simple diodes and transistors, all the way up to a microcontroller, DSP, RAM, ROM, Flash Serial Ports, TCP/IP, USB ports etc. During simulation, the schematic "comes alive" and can even talk to and control real external hardware or plug boards such as data acquisition cards and external test equipment etc.

The new release of VisualSpice Advance version 6 includes standard features such as 21 different types of circuit analysis including AC sweep, Single/Dual DC sweep, Operating Point, Transient Analysis, Pole Zero, Distortion, THD, Noise, Monte Carlo, Worst Case, three dimensional parameter and temperature sweep, Impedance Plots, Power Plots, Smith Charts, Polar Plots and more.

The built-in project browser helps you manage your schematic design project by helping you keep track of your schematic hierarchy, sub-circuits, libraries, and models used in your design. It allows you to view your design hierarchy in a tree format, and open any schematic in your design hierarchy with a quick double click of your mouse. The sub circuit design feature lets you design a circuit ones, and then re-use it in many other schematics. Circuit parameters can be passed from top-level schematic down to the lower sub-circuits. Library editor lets you design or modify your symbol graphics.

It includes over 25,000 active analog (SPICE) and digital device models (not counting resistors, capacitors or inductors). Advanced devices include Voltage Controlled Oscillator (sin/square/triangle waves), gain block, limiters, hysteresis blocks, one shot, magnetic core, derivative device, time-integrator, digital frequency divider, S-Domain transfer function, digitally controlled oscillator, and lots more. The built in import model wizard allows you import free models downloaded from manufacturer websites into the program.

VisualSpice Advance supports several MOSFET types including MOS1, MOS2, MOS3, MOS6, BSIM1, BSIM2, BSIM3.3, SOI, BSIM4, and EKV models, JFET, BJT, SCR, Op-Amps, Diodes, opto-couplers, regulators, multipliers, timers, sample-and-hold circuits, bridge rectifiers, power diodes, and more. The built in model editor lets you design new models and modify existing model parameters.

The library browser allows you to search for any device, and to sort them into categories for easy access.

VisualSpice Advance is a complete electronics lab in one program that includes built-in virtual test instruments that users can use to take readings directly off their live schematics such as a 64-channel real-time oscilloscope, Frequency Counter, Spectrum Analyzer, multi-channel logic analyzer, and of course a Multi-Meter which shows complex current, complex voltage, complex power, and complex impedance, complex admittance, reactance, and more.

The live simulation allows users to change component values while the simulation is running to see their effect on the circuit without stopping the simulation. Simulation results are displayed on the virtual instruments as the simulation progresses. No need to wait until the end to find out you entered a wrong resistor value by mistake. A digital circuit can be single stepped, break points and trigger points added (via the built in multi-channel logic analyzer). Plotting results is as easy as clicking on a wire even during the simulation to see the results on the built-in 64-channel live oscilloscope, with unlimited trace window.

Schematic output to VisualPCB layout is also supported. The VisualPCB package includes auto routing, manual routing, gerber file generation, import/export to Orcad, Pcad, EDIF, Cadnetix, DXF, Schema, and many other formats.

VisualSpice includes a built-in waveform designer that lets you design and preview stimulus waveforms such as PWL, SIN, AM, FM, Exponential, damped sin waves etc. Post processor function and scripting language lets you use and define mathematical equations and formulas to help you analyze and manipulate your simulation results, such as overlay one result with a previous result, or perform measurements on the results such as measure the period, rise time, fall time, frequency etc.

New real-time schematic animation feature shows which components are consuming the most power, current direction, voltage levels using different colors and arrows live on the schematic during the simulation.

VisualEDA design studio combines the power of VisualSpice Advance and VisualPCB in one powerful easy-to-use low cost schematic design simulation and layout tool.

VisualSpice is available now starting at only $99 for a limited time, and includes free lifetime technical support.

VisualSpice is available for OEM and the source code is also available for licensing. Contact Nigel Smith at Email Contact or phone 954-981-6998.

    This product should come with an enormous health warning.
    Not only does it not work properly, the "free lifetime technical support" consists of a telephone number which does not work and an ignored technical email hotline.
    The first approach of the technical hotline is to persuade people to upgrade. If you refuse to upgrade, you will be treated to a level of incompetence that would beggar belief.
    For example:-
    You ask: "My passcode is 12567. I can't re-install the package on a PC it used to work on last week but had to be reformatted"
    They respond: "That's because you have an old version of Visual Spice"
    You respond: "Hang on it worked last week"
    They respond: "Would you like to upgrade?"
    You respond: "Not at the moment. How do I get this working?"
    They respond: "Follow this web link and click on the embedded link"
    You respond: "That link doesn't work. The web page says it doesn't exist"
    They respond: "That's because you have an old version of Visual Spice. Want to upgrade?"
    You respond: "Hang on it's your web page that's broken. Nothing to do with Visual Spice"
    They respond: "OK what's your passcode"
    You respond: "I gave you that already it's 12567"
    3 weeks later and despite 13 emails, no further response from them.
    It's not just that though. Several other unfortunate customers have complained about the same thing - have a look in google. Most customers don't even appear to get the software at all after paying.
    If you are "fortunate" enough to get it working, the user interface is at best non-intuitive. No click and drag facility here. You use right hand clicks and all other sorts of complex actions to perform simple tasks.
    All in all this product is simply hopeless but worse still is the faint whiff of something not being right about Island Logix itself.
    As the title says, Buyer Beware.
