Hi, I have an "MT9VDDT12872HG" DDR sodimm module interface on my board for which I have to check the signal integrity.I downloaded the following Zip file "mt9vddt6472hg-40bd2_ebd" for the IBIS format.this contained the following files in it 1) mt9vddt6472hg-40bd2 ---->EBD source document 2) eeprom_nc ---->VeriBest IBIS Librarian 3) t27b_ddr400 ---->VeriBest IBIS Librarian I have mentor graphics - signal vision/signal analyzer tool for simulation. The EBD document contained the SODIMM details while "t27b_ddr400.ibs" file contained the IBIS files of different components. In the "mt9vddt6472hg-40bd2 ---->EBD source document" there are [Path Description]s given.In this, What are the units considered for values given in "Len" section.Please explain what parametres to be considered and how to start with doing the simulation of SODIMM interface with the IBIS files provided because the SODIMM module is with a different stackup and my design is with a different stackup. In case any one worked on this, Please reply ASAP!
