KIELER SCCharts Release 1.1

We are happy to provide a new release of the Kiel Integrated Environment for Layout Eclipse Rich Client SCCharts Editor and Compiler!


You can either download the Rich Client Application (RCA) which is a self-contained application bundled with everything you need to run KIELER SCCharts, or you can install the single KIELER SCCharts features via an update site on top of your own Eclipse installation.

  • You'll require a Java Runtime Environment >= version 1.8
  • With KIELER 1.1 we only support 64bit architectures

There is also a command line interface for the KIELER compiler. You can use the executable jar or a platform specific execrable file.

Known Problems and Limitations

Kieler on Mac OS

After downloading KIELER, Mac OS quarantines the application and, for some reason, considers the app broken and wants you to move it into the Trash.
Hence, if you want to use KIELER on your Mac, you have to remove the quarantine flag manually. You can use the following command:

xattr -rc ./

Collapse/Expand and Simulation Highlighting stops working (Fixed in 1.1.1)

After some time, usually related to diagram updates or synthesis option changes, the collapse/expand functionality of regions, as well as any simulation highlighting will stop working. This is caused by a bug in Klighd.

A possible workaround is activating the "Force simply update strategy" option of the Diagram view. The option is located in menu at the right side of the view's toolbar.

Bug Reports, Comments

We're working hard to make the graphical modeling user experience as convenient as possible. However, bugs can still remain in the code and some things might not be as you would expect them. Please don't hesitate to send in bug reports or give other comments like feature requests.
