Seamless In-Model Collaboration

Enterprise Architect's collaboration features have been significantly improved to connect team members and keep the iterative processes of modeling and design alive and healthy.

The chat / instant messaging capabilities are now expanded to allow one-on-one conversations with any other user in the model, facilitating an instant and productive "in model" dialog. Expanding on the group chat feature introduced in previous versions, the new one-on-one mode promotes highly focused discussions within the model and in real-time.

Setting Up Notifications

An all new notification system for chats and monitored discussions allows you to quickly and easily see when a new chat or discussion comes in that is relevant to you. Setting the new ‘Support Collaboration’ property on diagrams enables elements to show a notification icon when new chats and discussions have occurred and you are monitoring them.

To make use of this new mode for model chats,

  •  Set the "Support Collaboration" property on a diagram
  •  Place an Actor Element onto that diagram to represent a team member
  •  Specify their user logon ID in the Alias field
  •  Notification icons will now appear next to that Actor when you have an unread message from them
  •  Select an Actor with a 'New Chat' notification on a diagram to open the chat window to that conversation
  •  While the chat window is visible, the diagram selection and active chat are synchronized. 

Stay in Touch and Keep Informed

The new Collaborations window collects together the running history and moment to moment changes of the four central aspects of model based collaboration. Now there is one "go to" place to discover what is happening at the team level.

  • The Reviews tab provides access to recent and historical activity within either the current review you are joined to, or all reviews (filtered by time or status)
  • The Discussions window provides a  (possibly filtered) view of model based discussions, giving you an instant window into team discussions around particular model elements.
  • The Comments window provides a history of all elements that have Comments attached to them. Comments are a great way to informally note down requirements, concerns, delays, decisions and other material relevant to an element that does not form part of the actual model.
  • The Latest Chats window is a running list of most recent messages in the chat groups and personal chats you have subscribed to.

A clearer, more intuitive interface for model based reviews Improved Reviews User Interface and Functionality

An improved UI and Filtering

Reviews now have a cleaner user interface with extra filtering configurations. This allows you to pinpoint the desired review by its status, or show all reviews created, both current and past. The user interface has also been enhanced to easily identify reviews that have been locked but not approved by all approvers.

Reviews can now also be locked by a configurable Element Status. Locking removes the capability for a Review to be edited. This provides you with unprecedented control over a Review’s life-cycle. For example, you can lock all reviews with a status of 'Complete' or 'Reviewed' to preserve the decision making process for the current element for future reference. Reviews that have been locked by Element Status are easily identified by an '!' indicator on their icon.

To access the configuration for lock status see the Ribbon: 'Start | Configure | Model | Options | Review Status Locks'

Navigation of elements in a review has also been streamlined.

  •  The Manage Reviews window contains all the elements in the review, along with the Elements, Approvers and Review Topics.
  •  Browsing the element list with the Collaborate window open, switches context selection in the Collaborate window to display the selected Review.
  •  You can now filter the reviews using the context menu option 'Show by Status'.
  •  The Review history has been moved into the Collaborations window

Focus Window: Find your special places, recent files, and favorite items

New 'Focus' Window

The Focus window is a new tool to help you rapidly move through the model and find the places and items you are searching for. Four tools that were previously scattered throughout EA, plus one new tool, provide a central and convenient toolset to help you achieve your goals.

Together these tools help you find your special places, recent files, and favorite items. Get back into the model in record time and stay in touch with recent developments.

What's in the 'Focus' Window

  • The Model Views window. Create searches, pin favorites and navigate to the places that are important to you.
  • A new Quick Find window. Simple search capability that lets you find elements or diagrams in record time.
  • The Trace window. View and navigate the dependencies and connections of the currently selected element.
  • The Recent window. Instant searches that let you see what has been changing in the model in recent history. Stay in touch with recent developments.
  • The Revisit window. Open up that diagram, external file, document or window that you were working with in the recent past.

A user friendly way to navigate the project browser while inspecting elements

New 'Inspector' Window

The new Inspector window takes the Element Browser window out of the Project Browser and puts it into its own dockable window. Now it is possible to navigate the model and view element details at the same time. Selecting an element in the Project or Context browser will now automatically load the Inspector window with the detailed structure for you to browse and further edit and explore.

Integrated with External Elements

The Element Browser and External Element Browser have also been combined into the new Inspector Window. This provides a user friendly way to navigate the project browser while inspecting element features.
When you select an External Element from another system that is linked into this model, you can see selected details from that element as well. You will only see the External Element browser when you are connected to an external source element from Data Integrations.

Where to Find It

The Inspector window can be accessed from the Ribbon menu: 'Start | Desktop | Design | Explore | Inspector'

Exciting new API classes and functions allow you to select chart types, set data and configure styling

Enterprise Architect now ships with an all new JavaScript chart library that can be used to describe charts, their types, data and styling. This library can be called by an element with the SSDynamicChart stereotype and provides a chart that is filled via a script. Dynamic charts are refreshed whenever the diagram they are on is opened or refreshed, so the data is automatically up to date.

The new Behavior code editor view can be used to view and edit the script (Alt+7). This script will run automatically during diagram load to display the chart.

Integrations, Solvers and new Tools to Expand your Simulations

Version 15.2 is a major upgrade for systems engineers, technical architects and others wishing to couple their modeling and simulation work in Enterprise Architect with MATLAB, Octave, Modelica and more. All new "Solver" classes and a hugely expanded maths library  in the JavaScript engine provide a new and significantly expanded Simulation capability.

New Integrations and Solver classes.  An expanded Math library, new Dynamic Charts and much more.

Solver classes let you invoke arbitrary mathematical functions from Matlab or Octave at run time using a simple structured Solver API. Now you can link these powerful mathematical tools directly into your running simulation.

Custom model export to Matlab tools such as Simulink and Stateflow provide a platform for modeling and simulating advanced mathematical models and architectures.

Improvements to the Modelica integration and new ways of interfacing with GNU Octave further expand the options available to the Systems Engineer looking to take their active, state and parametric models to the next level.

The new Dynamic Chart library lets you tightly bind charts to simulations, letting you visualize aspects of your simulations behavior by using the Javascript engine to collect simulation data and feed it into a Dynamic Chart.

The Cephes math library has been totally reworked inside our Javascript engine and is now available for you to use within Simulations or for any useful purpose within EA.

And to make it all a little easier, EA will now let you view and edit Javascript code for every element on a Diagram in the built in code editor. Simply press Alt+7 on a diagram to see each element, and the operations and behaviors available to javascript and callable during simulation.


Version 15.2 now supports a new JavaScript construct called "Solver". We have initially provided solvers for integration with MATLAB and Octave through the built in JavaScript engine. Referencing and invoking functions in these external tools is both simple and intuitive, providing instant access to the rich mathematical libraries and capabilities exposed. Being part of the JavaScript engine these Solver classes are also immediately accessible to Add-In writers creating model based JavaScript Add-Ins.

Simulation Solvers
The Solver class allows you to use the functionality of external tools to perform complex tasks within your simulation. Each one integrates with an external tool to allow easy use of the functionality within that tool. Interchange variables between Javascript and each environment easily
MATLAB Solver:

    Integrate directly with the MATLAB API to use any of its calculation or charting functions


    Octave provides an alternative to many MATLAB functions
    Integrates with an Octave interpreter to use any Octave functions

Millions of engineers and scientists worldwide use MATLAB to analyze and design the systems and products that are transforming our world.

Enterprise Architect's MATLAB integration connects via the MATLAB API allowing your Enterprise Architect simulations and other scripts to act based on the value of any available MATLAB functions/expressions. Call MATLAB through the Solver classes, or export your model to Simulink, Simscape and/or Stateflow.

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.

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.

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

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


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

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


  • 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 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.

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.


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

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.
