Also remember that the training also depends on the environmental temperature. > I can completely understand it being a struggle now. At some point was I thinking of getting into tinkering with DDR3/4 on FPGAs Understanding of the different values for the registers which the tool recommends and validating the value is a real pain although some of the vendors such as Micron's datasheets explains things nicely. Xilinx MIG has a really dense guide and you really need to understand your timing etc. It is really not for the faint hearted.
