= Introduction =

The Unified Codegeneration project (UCGN) provides an open framework for the generation of high-quality source code which is suitable for safety-critical applications and certification ([http://en.wikipedia.org/wiki/DO-178B DO-178B]). Currently a Simulink/Stateflow front end and a C-language back end are included.

= News =

June 18, 2010: This project just came online... so bear with us as we keep adding documentation to this Wiki

June 21, 2010: Released the UCGN Simulink Distribution 1.0.1, including a "Hello World" Simulink example

June 28, 2010: Released SimulinkUcgnDistribution_1.0.2.zip, fixing two bugs (expression precedence and array copy indexing)

July 7, 2010: Released 1.0.3 which contains some minor bug fixes and robustness additions. Also, environment variables (with the syntax %VAR%) can now be used in the working directory property of the project xml files.

February 1, 2011: Released 1.0.4, enabling the use of Simulink enumerated types in Simulink and Stateflow models. This release also contains several bug fixes.

February 17, 2011: Released 1.1.0, the use of flowgraph loops in Stateflow is now enabled.

May 27, 2011: Released 1.1.1, bundling some smaller bugfixes.

August 30, 2011: Released 1.1.2, just some smaller bugfixes

March 29, 2012: Released 1.1.3, bugfixes and stability; also, updated to Simulink's new way of handling of Lookup/Interpolation, added sizeof operation to Stateflow

= Semantic Meta-model =

The Semantic Meta-model is the interface to the UCGN Code-generation. The meta-model uses XML/XSD to describe an abstract higher-order programming language, with object oriented features.

= Model Transformation: Simulink =

Currently included with the project is a Simulink model transformation layer. Matlab m-files are provided to export Simulink models and libraries into a domain-specific XML representation. The model transformation layer, which is implemented in Java, then takes this XML-model as an input and transforms it into a Semantic Model, for which the UCGN framework can generate source code.
