    Hi Arley,


    The IBIS model is correct. Only the name is not generate properly due to some bug from the Quartus.

    You can use the model that has been generate from the Quartus.

Hi Adzim,

Please, could you clarify what that means?

"The IBIS model that has been used is accurate."

Should I do anything to use to correct model for A15 (for instance)?

A15 ddr4_dq(15)~pad pod12_rtio_g48c_r48cp1_dqs_lv

Regards,

Arley

Hi Adzim,

Please, could you clarify your last help?

Should I use the model as provided by Quartus tool even though it is not correctly assigned to DQ model?

Look foward for you reply.

Arley
