Length matching of signals in PCB

[sivakumar_tumma]

Hi,

I am facing some problems with length matching of the signals. I can understand , all the data , address and control signals should be of same length with some specified tolerance..

But in real world , it is always not possible to have that scenario. Then group wise address, data and control signals can be length matched. How tolerance of length of the signals will be decided ? I am not able to clearly understand , how to go about it.

Can any one explain how to go about it or can give some material ?
