I am designing a Custom based on IMX6Q/D/Dual Lite and using four DDR3 and planning to use Fly-by topology for routing.

 

HW Design Checking List for i.Mx6 Rev2.5 has Ref-a5 that has recommendation for DDR3 routing by group. Does these guidelines apply to tree topology routing only? If yes are there Fly-by topology guidelines as well.

 

Please let me know as I am setting up the routing constraints and will be very helpful.
