Generate component diagram from source code in EA

问题:

I'm currently working on EA. I have a task to generate UML diagram from source code by using EA. I found the way to generate class diagram. But i need to generate component diagram directly from source code.

I have analyzed and found that it is possible using one of the three methods :

1.Scripting,

2.Grammar Editors,

3.Code Generation.

Could anyone help me to know the procedure to generate component diagram automatically....
