Hi experts,
         I am working on boards having DDR interface. on layout  we are
following the below groupings & length matching


 Group1- Data signals,strobe,Mask with in group +/-10 mils tolerance
 Group2- Add/Ctrl/Cmd/Clk--with in group +/-10mils tolerance

         i am clear on groupings but on length matching i want to know how
to calculate the exact Min & max length matching tolerance .

              can you please let me clear on DDR length matching?


Thanks,
Karthikeyan
