4. ProblemDefinition Source XML file The XML file describes a system Thesystem has manycontrollables Eachcontrollable has inputs, outputs, params, faults… Target .h and .cppfileforeachControllable The generation of the .H file is straightforward The generation of the .CPP file comprises several RuleSets Locals: For each input/output/param/fault/timer define a local of that type doInit initialize each local variable by getting its value (using mappings in wtsl) WHY IS USED? We’ll use MDWorkbench forthatpurpose
5. MDWorkbench MDWorkbench is a model-driven engineering development environment to build: Source code and text generators Word documentation Model transformers Eclipse-based IDE Java code may be used in MDWorkbench projects Developed by Sodius SAS
