The recommendation to use a counter is a good idea. --- Quote End --- Thanks for the advice. The idea of Alex's suggestion is clear. It seems me strange that i turn on PLL Auto Reset (that automatically self-resets the PLL on loss of lock), PLL reconfiguration and clock switchover is not enabled in the design and i still have a warning: "The reset port on the PLL should be connected. If the PLL loses lock for any reason, you might need to manually reset the PLL in order to re-establish lock to the reference clock."
