In Mai 2008 dSPACE published the latest version 2.1 of the "Modeling Guidelines for MATLAB/Simulink/Stateflow and TargetLink". The guidelines address best practices for TargetLink models. 

The Model Examiner V1.4 especially focuses on the adoption of a safe language subset for code generation wth TargetLink.
