Project State

Events of the last year

After a one-year consolidating phase, during which the topics usability and stability were addressed, AutoFocus 2 is in a good and stable state. The editor handling was improved continually, bugs were corrected and additional features and functionalities were implemented. Furthermore the development infrastructure was greatly improved. The source code management was moved to a Subversion repository; the source code structure was harmonized and uniform build scripts were installed.

The project advanced in important steps with regard to value preservation of the AutoFocus tool which is already older than 10 years in some parts. AutoFocus 2 is now primed for usage in case-studies of embedded systems and for the further developments.

Current development activities in AutoFocus 2

Currently, planning and preparation of a student software engineering practical course are underway and scheduled for the winter semester 2006/07. The target is the next step of evolution of the AutoFocus 2 application. The AutoPLACE (AutoFocus Product Line Analysis and Construction Extension) project aims at a productline-based software-engineering tool for embedded systems based on AutoFocus 2.
