dear friend thanx for reply
but it will increase clock skew. It will again be a problem.

Setup violation may fixed by increasing clock duration but it will cause clock skew. The solutions of this issue are
Increase setup and hold safety margins.
In critical cases you may design circuits for optimal set of clock.
Connect two or more flip-flop in a chain
