= Welcome to Cheddar Wiki =

Cheddar wiki is a web-based platform for Cheddar project management.The following main facilities are available :

Cheddar is a free real time scheduling tool. It is designed for checking task temporal constraints of a real time application/system. Systems to analyze can be described with [http://www.aadl.info/ AADL] or with Cheddar specific language. Cheddar is developed and maintained by the [http://www.ea2215.univ-brest.fr/ LISYC] Team, University of Brest and [http://www.ellidiss.com/ Ellidiss technologies].

Cheddar relies on [http://ocarina.enst.fr/ Ocarina] to provide schedulability analysis of AADL models. The ocarina team also uses the Cheddar analyzer for their research projects and some tutorial/labs. There is a strong cooperation between the two teams.

Cheddar can be run as a [http://www.ellidiss.com/ STOOD] or as a [http://www.topcased.org/ TOPCASED] plug in. The interoperability of STOOD/TOPCASED/Cheddar is managed by Ellidiss technologies. There is also a strong cooperation between the Cheddar team and Ellidiss technologies to investigate how Cheddar can efficiently analyze AADL models built with STOOD.

Cheddar is written in Ada/GtkAda. Cheddar runs on Solaris, Linux and Win32 boxes and should run on every GNAT/GtkAda supported platforms (see [http://www.act-europe.fr/ AdaCore web site] for details).
