i have a design where the critical path (from souce FD to destination FD) gives a slack of -3.3ns (period constraint is 10ns).
 
now is there any other way to constraint the critical path other than putting the period constraint on it? (there are no false paths or multicycle paths).
 
is my understanding correct that if i apply the period constraint of 10ns, then all paths connected to that clock are constraned to that period and that would automatically constraint the critical path as well?
 
if i apply 10ns period constraint to my design, then is there any way of tightening up the constraint on the critical path specifically? so that the slack is reduced?
