"negative" required longest p2p time

Hello, everybody. I've a small problem with Quartus II message report. First of all, when I compile my project, time requirements are not met. I read the report and I found a lot of errors ...

Hi, everybody.

Finally I found my problem. At the end of compilation I read:

warning: found 1 node(s) in clock paths which may be acting as ripple and/or gated clocks -- node(s) analyzed as buffer(s) resulting in clock skew

info: detected ripple clock "generatore_clock:inst|divisore_clock:inst4|clk_out" as buffer

Quartus Help suggested me to set constraints for the suspect clock.

Once I did it, all went right.

Thank you all for your support.

See you.

Bye bye,;)

Alessio.
