Enterprise Architect now integrates with Simulink

MATLAB Simulink for SysML Simulations

Enterprise Architect now integrates with Simulink

Using Enterprise Architect 15.2, you can now run SysML simulations in Simulink as well as Modelica.  Enterprise Architect will translate a SysML model into the Simulink format and automatically run the simulation, plotting the outputs of the selected variables. The generated Simulink file can also be opened directly in Simulink allowing modification and fine-tuning of the simulation settings and output functionality.

• Drag-and-drop access to common built-in Simulink library blocks directly through new Enterprise Architect patterns or reference your own custom built blocks with new SysPhS standard stereotype parameters.
• The Simscape extension to Simulink is also supported to model physical systems with physical flows, allowing access to Simscape's vast array of library blocks across many different physical domains.
• State Machine guided simulation is supported with the Stateflow extension to Simulink.

 

 

 

MATLAB Simscape for Physical Systems

Use the Simscape extension to Simulink to model physical systems

Enterprise Architect can now translate SysML internal block diagrams into MATLAB's Simscape, which is an extension to Simulink, and instructs MATLAB to simulate and plot the requested outputs. This allows simulation of physical systems where components represent physical objects and flows represent physical substances or energy, for example water flowing from one tank to the next, or current flowing through a resistor.
Access the vast array of pre-built Simscape library blocks, or create references to your own custom library blocks.

 

 

MATLAB Stateflow for State Machines

Guide your SysML simulations in Simulink with State Machines. The State Machines are translated into MATLAB Stateflow diagrams.

• Leverage the power of MATLAB to simulate your state diagrams
• Easy export and run capability

 

Connect with GNU Octave's Advanced Math

Use the Octave 'solver' class to integrate with Octave

The open source Octave project provides a rich library of mathematical functions you can leverage in your models and in your Simulations

Example

An example of a Script in Enterprise Architect that calls Octave to perform a plot of the math function is shown in the image below. In this case there is a square wave generated and this is processed using a Fast Fourier Transform to give the amplitude of the harmonics that form the square wave.

• Create an Octave solver in JavaScript
• Invoke the math capabilities of Octave to guide simulations
• Integrate with charts and other model elements

 

 

New and Expanded Support for Modelica

Export of Models to Modelica has been expanded to extend support for Modelica capabilities

 

 

OpenModelica

• Now supports SysPhS for defining constants and variables within the SysML blocks rather than in the Simulation configuration
• Supports showing the Block diagrams in the OMEdit - OpenModelica Connection Editor
• Supports referencing existing Modelica library blocks, or custom user defined blocks
• Now shows alias and notes in OpenModelica Connection Editor

Create blocks on the fly using the new SysPhS patterns ready to be simulated in OpenModelica. With the latest OpenModelica code generation you can view your SysML components in OpenModelica, as well as simulate plots.

 

 

OMG SysPhS - An Open Standard for Integrating Systems Models with Mathematical tools

OMG SysPhS Standard

Enterprise Architect now also supports the OMG SysPhS standards, enabling you to stereotype variables and constants within a simulation and assign various options to those variables. This provides a visual approach to setting up a simulation by including the constants and variables in separate compartments on your blocks. It also has the added advantage of making the simulations easier to share as they are now model based.

 

 

Quick and Easy Access to all the Script Code behind your Simulations

New code editor capability supports the visualization of all the code and behavior scripts for all elements on a diagram.

 

Single Code Editor

Editing the Javascript code in behavioral models such as statemachines and activity diagrams has been improved to allow all the behaviors of such diagrams to be edited in a single code editor. The code editor for these elements include a structure tree allowing navigation and editing of any child element behavior.

Structure Tree

Previously one had to press F10 or bring up the properties dialog for every single behavior which required viewing or editing. Now every behavior can be edited in a single editor with a structure tree allowing quick navigation to child elements.

 

All New Dynamic Charts based on Simulation Results

Create easy to read, visually informative charts from your simulations

• Save the results of your simulation as visual chart elements
• Charts populated by simulation results can be easily included in your reports
• Share user friendly simulation results with stakeholders without requiring any additional simulation tools

 

 

JavaScript Engine now supports Advanced and Integrated Math Capabilities

The Cephes Math Library

The legendary Cephes math library has now been fully and tightly integrated into the JavaScript engine available with Enterprise Architect. This library is a collection of more than 400 high quality mathematical routines for scientific and engineering applications. This provides a huge range of mathematical potential for modelers wishing to take their engineering and systems models to the next level.
