dsp builder-Prewitt edge detector

Hello, I have to present what exactly do all of implementation of Prewitt edge detection design in Dsp-Builder. I find informations in "Edge Detection Using SOPC Builder and DSP Builder Tool Fl...

I'm trying to use that dsp builder example tutorial too to learn how to use Simulink and NIOS for image processing purposes (Stratix II DSP Kit v1.0.0. Reference Designs AN364.pdf).

But when I open the simulink file test_sopc_edge_detector.mdl, I have a lot of 'Bad Links' being displayed. I guess this is because I am using a newer version of DSP Builder, and I am now in the process of looking for DSP Builder 10.1 equivalent components and replacing each term one by one. But the problem is that I don't have the exact parameters of the components used and I am not sure if I am doing the correct substitutions. For example:

- Do I substitute bus_alteradspbuilder/Input with Input or Non-synthesizable Input?

- There is an 6-input pipelined adder in edge_detect_h, edge_detect_v and combine_prewitt_v_h files. How do I find this component?

- What are the parameters to set in the counter used in gen_data_valid?

Or is there another more up-to-date tutorial for this edge detection example?

Thanks
