How to write TLC:Code generation Advisor

Hi,

Recently, all our models are changed from 2007b to 2011b. As a result of which the existing code gen scripts are encountering many issues.

Could you please tell me how to overcome this issue? How i can co relate 2007b code generation process to 2011b code generation process? Also, could you please brief me about new feature added in 2011b, that is “Code Generation Advisor” ? I am very new to code generation process. So can you please give idea about code generation? What is TLC. How to write TLC?

Thanks, Uday
