Timing red [Copy link]

After the full compilation is completed, the timing report is red. Doesn’t this mean that the timing is in violation? Why is the result correct after downloading the board?

The board may be correct or wrong.

Why is it possible to be correct if the timing is already violated?

Set the clock first, then constrain inputdelay outputdelay and timing exceptions, and the timing will basically not report errors.

I guess you are using QUARTUS. If you don't have timing constraints, the message will turn red. Find a book to learn how to design timing constraints.

Yes, it is indeed. Thank you very much.
