I am performing SI EYE analysis for the DDR3 interface. Following are my consideration for the DDR3 SI analysis:-

Data rate= 800MHz/ 1600 MT/s

Data UI = 0.625ns = 1/800MHz

Address, command and control UI = 1.25ns = 1/1600MT/s

But I am little bit confused in selecting the exact Data setup time and Data hold time values

and

add,cmd , ctrl setup time and hold time

May I know the perfect way to select the setup time and hold time for the DDR3/4?
