Nios 2 hardware development error

Hi ,

I wanted to explore NIOS 2 processor, so I started with NIOS 2 Hardware development tutorial. I have also attached my design file for reference. but strangely after I create the Qsys design, I am unable to generate the the hdl files for synthesis . It gets struck saying "Info: Starting classic module elaboration."

Can someone provide me any suggestion on how to generate the files and why it happens..

Thanks for your time..
