General Board / SysML Requirements
« on: July 20, 2009, 07:00:32 pm »
Hi, has anybody tried to enhance the SysML Requirements elements with additional tagged values similar to the description in the Requirements Management with EA white paper?


General Board / SysML Requirements
« on: June 30, 2009, 07:41:37 pm »
I am just starting to work with the SysML technology for EA and in particular the SysML requirements diagram.

One of the issues the I observed is that the notation used by EA appears to differ from what I find in the SysML 1.1 specification from November 2008. In particular I miss the text attribute in the EA requirement element. EA obviously uses notes instead of 'text'

Is there by chance a summary available that list an/or explains differences between the SysML specification and how it is implemented by EA?

Also, is there any possibility to override the tag definitions in the SysML requirements extension, such for example that I take out the risk and the source tags, and add others, such as 'verifiedBy'.

Additionally I missing the Requirements table described in the SysML spec, the elements list is similar, but not quite the same.


I had pointed this out already quite some time ago and had hoped that this functionality would have been made available with EA 9. Support gave me the same hints, that would have made the diagram look like describing internal transitions (with some restrictions), though the functionality would not be like an internal transition. Support told me that they will register internal transitions as a feature request, but no commitment was made (I didn't really expect one either), if or when they would be supported. Other tools (even free tools) are better here.
Support for concurrent regions is not very good either, using explicit initial states in each regions (I thought that this is permitted by UML) result in EA complaining on model validation.
In general FSA modelling support is still quite suboptimal in EA and I have not seen much improvements over recent versions.

I had this too.  You may find that you need to rest the commands that you see on your menus after you have upgraded.  You can do this from the Workspaces and Commands dialog which is accessible from the Workspaces and Commands... menu item on the View menu.  Select the Commands Tab then check the Documentation  box (or explore the tree and just enable the bits you want).

Good luck!

Thanks, that helped.

I recently upgraded from EA 9.2 to 9.3 and cannot find my usual generate documentation menus anymore. As far as I interpret the documentation, right click on a package in the Project Explorer should produce the following menu (as with EA 9.2)

Instead I get something like this with EA 9.3

Thanks for any hints.

Bugs and Issues / VSIntegrate installation problem
« on: June 06, 2011, 03:51:51 am »
I have problems installing Visual Studio Integration on a Windows XP system, both with 4.0.4 and 4.5.7. Installations starts but terminates with a Message:

Error 1316: A network error occurred while attempting to read from the file....

In the installation dialog, the last message I get is "Registering product..."

Any idea what goes wrong here?


The installation file is however local on my disk and

Bugs and Issues / Re: Hyperlinks in NOTES (864) not working?
« on: February 18, 2011, 03:01:18 am »
In fact it would be quite nice if one would be able to link to hyperlinks themselves from within notes.
I have created a custom diagram of custom type documentation in my model in which I pool a number of hyperlinks to external references, such a specifications etc. No I would like to refer to those link from all over the EA project. Hyperlinks however do not appear to show up as elements in the project browser. Pretty much as I would do it in a word processor with the list of references.
Is there any tweak how to achieve this?

Uml Process / Re: Question concerning optional concurrent substa
« on: May 16, 2014, 09:03:35 am »
I just had a look at the 2.4.1 superstructures specification, and to my interpretation, Figure 15.35 - Orthogonal state with regions, corresponds to the notation that I used in my example.

The example that I referred to is in  Abbildung 14.67: Parallelität durch Verwendung von Regionen  on page 369. I have the PDF version of this book. I will have a look in the superstructures document tonight.
By the way, thanks for the hint with the dependencies in the class diagram.

Thanks for the reply. The two initial states in State2 of the Class1 FSA I used as I had seen in literature (UML 2 glassklar 4. Auflage) that they used an initial state per concurrent region. I spotted that EA flags this as an error or a warning when one validates the model, though I'm not sure what is in fact the correct UML way.

Uml Process / Question concerning optional concurrent substates
« on: May 15, 2014, 09:06:05 pm »
I have a general question concerning modelling of concurrent sub-states in FSA diagrams. My basic class model would look like follows:

Class1 is mandatory, Class2 is an optional extension to Class1. The functionality implemented by Class2 requires the existence of Class1. To model this I use a composition to whole with multiplicity 0..1 at the Class2 end and 1 on the Class1 end. Each of the classes features its own FSA. The Class2 FSA however should become active as a concurrent sub-state of Class1 State2, and given that Class2 is optional, the concurrent sub-state should be optional as well. Also Class2 shall be destroyed when I reenter State1 in the FSA for Class1.

I don't know if this is formally correct and compliant with UML. I also have found no hint if it is in fact possible at all to mark a region as optional.
In the project browser my model looks like below:

When I want to add FSA2 to the concurrent region of State2 should I use add as Invocation, or add as Link. The latter moves FSA2 in the project browser from being subordinate to Class2 to State2 instead which is probably not the desired behavior.

I wonder if anybody has tried to use the EA MDG integration with products that are based on the Visual Studio 2010 Shells. I've had some sort of success with the Python Tools for Visual Studio. I now wonder if the integration would for example be also possible with AVRStudio 5 by Atmel which appears to be based on the Visual Studio 2010 Shell.


Hi, is anybody having an example data type description file that adds the C language stdint.h definitions to EA? The help info on the programming languages data type does not really explain all the fields.

Thanks, this worked.

I installed Visual Studio Integration 4.5 for EA 8.0.864.8 on a Windows 7 64bit system, however in the Manage Add-Ins dialog I find it only as administrator and not as standard user. Any hints?
