New 3D plots and animation

New high-level matrix manipulation language

Delivering unmatched power, flexibility, and extensibility, VisSim 7.0 is the most sophisticated dynamic simulation environment on the market today. New features in this release expand your modeling, simulation, and visualization options

Modeling Features

• New 3D Plot Block
  Allows interactive plotting of multiple trajectories, surfaces, or waterfall frequency plots. Plots support auto scaling, customizable axis appearance, control of lighting, surface color and mesh highlighting. User can zoom, translate and rotate plot with mouse to inspect plots during and after a run.
• New 3D Animation Blocks
  Animate mesh data directly from a DirectX .x file or connect to objects in a 3D VRML world file. Animation objects can be zoomed, translates and rotated with mouse to inspect animation scene during and after a run. 3D Camera and light blocks allow interactive control of lighting and world view.
• New Matrix Blocks
  Spreadsheet matrix constant block, scrollable spreadsheet matrix display block, eigen value finder block, linear system solver block, spline and polynomial curve fitting with data lookup
• New random distribution blocks
  Beta, Cauchy, Erlang, Gamma, Pareto, Rayleigh, Triangular and Weibull distributions have been added.
• New Time stamp block
  It produces a user formatted date and time. This can be combined with the new file name variable expansion to create unique
  time stamped export data file names.
• Code generation support for latest TI chips
  Support has been added for the latest TI F2835x and MSP430 parts from Texas Instruments. Code generation efficiency has been increased so that closed loop control rates in excess of 8 loops running at 300 KHz has been attained.

Simulation Features

• Subsystem threading
  For compound blocks with local time steps, a code generation option allows the subsystem to be scheduled in a low priority idle loop as a separate thread.
• Event Logging
  A new eventLog and eventLogDisplay block allow quiet background logging of system errors and events without disturbing the overall system run. Events can be logged directly from the diagram or from user written DLLs. The VisSim real-time analog data subsystem now uses the event log to avoid halting a run upon the encounter with an unexpected event.
• Time Delay block handles
  Complex data The continuous time delay can now work with complex data
• Min and max blocks now handle scaled int
  The min and max blocks will now simulate and generate code for fixed-point scaled integer inputs
• File name macro expansion
  The VisSim Macro expansion facility has been expanded to include standard VisSim variables. String variables are used verbatim, numeric variables are converted to text before expansion.
• Start-up scripting
  Enhanced matrix syntax adds cos, diag, eye, exp, inv, log, log10, min, max, ones, rand, sqrt, sum, sin, reshape, zeros as well as standard arithmetic operations.
• Import block feature
  Improved to read and write .csv files. The import block now understands 0xabc hex numbers..
• Export block feature
  Improved to allow large user specified header text, force output of trailing zeros for column alignment, optional time stamp for each row of recorded data.

Visualization Features Description

• Compound block coloration
  You may now specify custom colors for individual compound blocks. Compound blocks with a local time step are colored with a green cross hatch.

General Features

• Key shortcuts
  Ctrl+A selects all blocks; Ctrl+Z undoes last operation, Ctrl+Y redoes last operation. Ctrl+F4 closes current window.
• New tool bar icons
  Improved tool bar icon legibility makes buttons easier to read on high resolution screens.
• Autosave
  Guarantee simulation integrity with an autosave option
• Printable area delineation
  An optional blue box shows the part of the model that would be printed given current print settings.
• Automatic file reload at startup
  Get working faster by automatically reloading the last saved model at VisSim initial startup.
