Fixing Transition Violation

Transition violations can be fixed by different methods based on the design situations.


 
They include:

 
  • Up sizing the driver cell 
  • Decreasing the net length by moving cells nearer or reducing long routed net 
  • By adding buffers 
  • By using existing spare cells as buffers 
  • By splitting loads through buffers to reduce the fan out number (number of driven cells)
