What is the Difference between CLOCK CELLS and NORMAL CELLS in physical design.
 

Things u may already know

clock cells will occupy less area compare to normal cells.
leakage power for normal cells is high compared to clock buffer.
clock cells have equal rise time and fall time.
clock cells have capacity to drive high fanout.
parasitics will be less for clock cells compare to normal cells.
Normal cells will help to achieve timing compare to clock cells.

sorry if it not helps u..
 

Except one thing every thing favours to use clock_cell i.e timing.
why does timing is disadvantage.
 

yes when it comes to Timing the celldelay and output netlength varies for each and every path.. so Most cases clock cells will result in consuming timing..
