    两种做法，应该都可以做到。就看芯片内部怎么实现的吧？

另外，为什么是调整DQS，而不是调整DQ group或者单个dq一次调呢？

“Read training” collectively refers to gate training and read data eye training.
The goal of gate training is to locate the setting at which the initial read DQS rising edge aligns with the rising edge of the
read DQS gate.

所以后续还要进行write leveling, MIG手册提及了这一点。
