EBD Question??

I have a LineSim schematic setup with a LPDDR2 bus.  The DRAM has an IBIS model as well as an EBD file.  After running the simulation I have more probes than I expected?

 

DRAM1 is the reference designator.  On the O-scope screen I have the following pin listings

 

1. DRAM1 with what appears to be the .ebd pin numbers (AA23, AC6, ect).  I also have a listing called

 

2. J_EBD (EBD-DRAM1) which also has the same pin listing? 

 

3. U0 (EBD-DRAM1) with what appears to be the pin listings for the IBIS model

 

4. A listing of what appears to be each individual RLC element of the .ebd file

 

The waveforms looked slightly different between the probe locations DRAM1 and J_EBD (EBD-DRAM1).  What is the difference between these probes??

 

I would like to view the waveforms at the die locations after the board descriptor file.  Which probe locations should I be looking at?  This is terribly confusing.
