Problem in implementation of Image Resizer

Hi, I wish to implement the following scaler IP from Altera.

http://www.altera.com/support/examples/dsp-builder/exm-scaler.html

I followed the steps in the following readme text to use the Image Resize example.

ftp://ftp.altera.com/outgoing/download/support/examples/scaler-readme71.txt

I have also installed DSP Builder 7.2 and Quartus II 7.2

However, when i run simulation, I encountered this error

Error reported by S-function 'sGeneric' in 'example/scaler':

An error occurred whilst loading the Cycle Accurate IP / HDL Import simulation netlist DSPBuilder_example_import\scaler.vo. Please regenerate the corresponding block.

Furthermore, when I tried to open the scaler block, I had this error

"Error evaluating 'OpenFcn' callback of MegaCore AlteraBlockset block (mask) 'example/scaler'. Error using ==> testscan

First input can not be empty.

Please advise me on this. Thank you. I hope to be able to generate the output video from this resizer using the tools.

    Hi mobiusx,

    I think the models online are for 7.1, therefore, not quite compatible with your 7.2. However, the model looks like a pretty simple one and shouldn't be too hard to upgrade to 7.2... Please feel free to ask if you need help.

    thanks alot! for that updated example

    I have tried it out but the problem is that it has been scaling for more than 12 hours.

    Does it take that long to do so?
