Timing Analysis

Hi, I don't understand because I recived this error. This is the report with timing analyzer

please help me. Thanks

Wow!  That's a lot of levels of logic for a combinatorial path.  Are you using loops in your code?

Also you didn't post the error message (where did you get "error 31")?

"please help me."

Take a course on Digital Logic Design.

I have resolved the problem.  The result now is this.

Data Path Delay: 30.778ns (Levels of Logic = 32)

thanks
