Hi everybody, I read the similar subject here but I didn't find the solution of my problem. 

 

I have an image processing project, I'm sure that there isn't any error in algorithm and files which I added to project. But when I loaded .sof file to Cyclone II, it's written there is no signal at the screen. what can be the reason of this problem? 

When I compiled project, there isn't any error but there is Critical Warning: Time Requirements not Met. I think maybe problem is sourced from this warning and I have to add .sdc file.. what do you think about this?

If you are sure your project files are correct, then your problem could come from timing. You should at least declare your input clock frequencies and the input/output timing requirements. Have a look at this user guide (http://www.alterawiki.com/wiki/timequest_user_guide).
