Cinderella SDL is a visual modeling tool for developing embedded software systems,
communications services, protocols, or any kind of message/signal based system.
Cinderella SDL is based on the specification language SDL, standardised by
the International Telecommunication Union, ITU. SDL is a powerful
object oriented graphical notation that supports analysis, design,
implementation, and testing:
Analysis and simulations of your SDL designs.
Standardized notations like SDL, MSC and ASN.1
Import/Export to other SDL tools
The Integrated Graphical SDL Editor, Analyser, and Simulator
fully support the specification language SDL. SDL is a general-purpose
object oriented language especially suited for specifying embedded systems
The Cinderella Incremental SDL Analyser is the most advanced SDL
analyser on the market today. The analyser works in the background while you
are developing the specification. It even provides automatic error
correction for certain types of errors.
The Specification Explorer is a versatile user configurable and
extremely powerful tool for browsing and editing a specification.
The built-in simulator simulates the specification immediately, i.e. no
compilation to an executable file is necessary to simulate a specification.
You can even simulate partial specifications and update the specification
Cinderella SDL supports the Common Interchange Format (CIF), an open
standard defined by ITU, so it is easy to exchange specifications between
different SDL tools. Textual to graphical SDL and reverse converters are
