Hi all,
I have DDR connections coming to DDR DIMM (J3) from processor (U1) thru the
series termination. It also has the VTT end termination.
I have defined the net as Xnet, as it makes my length matching simpler. Now
the problem is:
While using Constraint manager, I need to define pin pair for the match
group. Because I am not bothered regarding the length from DIMM to end (VTT)
terminations.
So I create pin pairs from U1 to J3.But I need to repeat it for all 64 bit
databus,13bit address,3 clk's etc... which is very hectic work.
Is there any process to make my work simpler..
Regards
Chew.Wang
