Download Code Generation from Cinderella

Code Generation from Cinderella-SDL to Embedded Platforms
files. They can use internal Cinderella API functions to extract all the needed components out. It is
easier than reading in the SDL text specification and parses it directly. So I chose to use C++ to
program and compile the program into DLL extension file as plug-in.
After we have made all the things clear, we made a workflow table 4-1 for future work.
Stage 1: Study Cinderella API and the examples
Stage 2: Practice to extract all elements needed
Stage 3: Adopt the structure in extraction
Stage 4: Compile the generated codes
Stage 5: Test code on AvR micro controller

4.3 Elements Classification and Analysis
In SDL, the elements are classified as architecture, behavior, communication and data four
sections. However, in element transformation, this classification is proper. In order to give a clear
and systematic structure of the SDL elements, we try to categorize all the basic and important
elements into three main types:
1. Structural element. These kinds of elements have their own scope diagrams.
2. Definition element. Elements specified in text symbol.
3. Behavior element. Elements specified in behavior description area.
The structural element consists of system, block, process and procedure diagram elements. In
definition element field, signal definition, data definition and variable declaration will be found.
Behavior elements are used to specify the behaviors of process. It contains symbols which
composite the behaviors of the process. They are classified as: start, state-trigger and free action.
There are still some detailed categorizations left. We will shoe the whole element structure in
Figure 4-1.
