Hello folks, I use Quartus II 8.1 and DE2 board. When I compile my design I don't have errors in report, only warnings. But, looking at the report window I can see that my design don't meet t...

Honored Contributor --- Quote Start --- I just want to see which is maximal operational frequency for my design.

You may not need to set them - it depends on your design. --- Quote Start --- Which value should I set to these parameters to see maximal possible clock frequency for my desing? --- Quote End --- The timing settings will be determined by your design. The fitter will place and route your design and try and meet these settings. I think you need to read up on this subject - it's too big a subject for a forum really. If you set the fmax to be a lot higher than you really need then you can overconstraint the design and make it more difficult for the fitter to meet timing requirements - give it realistic requirements. If you haven't set any timing requirements I'm not quite sure why you are getting the message that your design doesn't meet timing requirements.
