signals of the DDR controller for various loadings, which can be useful for a system utilizing the DLL.
These numbers are the result of simulations for one topology. The delay numbers will strongly depend on
the topology used. These delay numbers show the total delay for the address and command to arrive at the
DRAM devices. The actual delay could be different than the delays seen in simulation, depending on the
system topology. If a heavily loaded system is used, the DLL loop may need to be adjusted to meet setup
requirements at the DRAM.
