    EBD Question??

    kirk.fabbri

      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.
