Simulation, UniPHY, Calibration

DDR3 UniPHY.

Can't seem to get Quick or Full calibration working in simulation.

Any ideas / pointers to how to get calibration to show up in simulation?

How do I know? MRS[1] never gets writing leveling bit.

And with or without calibration I always see the wrong write signal timing.

The reason to try: the timing of the write signals are wrong at the memory interface.

DQS and DQ seem to occur about 1/3 of a cycle too soon, before

DQS should based on write CAS latency of 6.
