If you hope to set the differantial shunt resistor with ibis file. You should create a .ref file for the RDRAM EBD like this first
* RefDes model Assign File*
R19, r_120.ibs, r_120(open r_120.ibs, see what component name is it)
Then click Menu Model - Assign Model by Reference Desinator, load your .ref file.
I have assigned the EBD model in "Assign Model by Reference Desinator".
In the RLDIMM EBD model, it has included the definition for the resistor:

So, if it means I don't need to set others? that is, this RDIMM EBD model has defined anything, I don't need to set others for this EBD model in Hyperlynx 8.1. And next setp I only need to run the "DDRx Batch-Mode Wizard" to do RDIMM Post-Simulation? Thanks.
If EBD itself speicifies IBIS model assignment, you have no need to select IBIS model for components inside EBD anymore. Before running DDRX wizard . I strongly you contact with Mr. Hu jianwei(he is intrumental in helping user to get hands on). Additionally, Following items you may take based on what happened
1) you may need to set the pin direction for BI/Tri pins.
2) don't forget copy those ibis model files under your design directory
3) Upgrade your 8.1 to 8.1.1
Thank you, yanfeng, our hyperlynx had updated to 8.1.1.
