I am trying to design a pcb using i.MX6UL and I am having a huge trouble routing the Address, Command and Controll on the same layer for DDR3. As the rules suggest all of this pins need to be in same layer but is quite difficult. Also I see some designs where it seems they didn't follow this rule. i.MX6UL development board, DART-6UL.
Is there any reference design that we can follow to route or we should separate the pins between the layers like the reference design from i.MX6UL development board?
Thanks in advance,
