How to resolve max transition violation related to clock nets??

can anyone explain me
 

I don’t think any P&R tool fixes the max transition problem, once clock tree is built. Designer has to fix it manually.
 

Hi,

Max transition violation is b'caz of more load. To solve that do cloning or insert the high drive strength buffer in that path.

Prithivi.
 

Basically, either you specified a clock slew that is too loose or your cts tool is crap. Try specifying a tighter slew in cts.
 

How to specify tighter slew in cts ? wt value shd i give their?
in sdc it is given as set_max_transition [current_design] as 1
but i am geting 1.43 which is much larger than 1 so wt shd i do?
