    Hello Denny,

    The DQGATE routing length  specified in the datasheet must be followed. All of the specifications in the datasheet are mandatory, and TI cannot guarantee that the DDR will function unless all are followed.

    I don't have any specific data points on the "what's propose of those requirements" but we have seen memory failures if the length is too short or too long.

    Regards,
