How to solve this Fitter error?

Hi,

​

As attached file, Quartus shows "Fitter require X LABs for clock region in ..., but only Y LABs available ...".

What does this message mean?

Do you have any suggestion for solving this problem?

    Hi,

    This error is issued when the legal clustering cannot be found in a region. It could be a clock region, a Logic Lock region, or an intersection of both.

    In this case, please increase the size of any Logic Lock region or the clock region in the corresponding locations.

    Thanks.
