Recently, I'm going to layout a board which has a 200 pin SO-DIMM DDR slot, a DDR 333 memory module will be plugged in. Now, I wanna to simulate the data/command/control signals of the DDR traces between the MemoryControlUnit and the SO-DIMM DDR slot. I has got the ibis module of MemoryControlUnit, how can I get the ibis module of the 200 pin SO-DIMM slot? Or is there any other way to do this simulation?
I've downloaded the ibis module of DDR 333 memory module from www.micron.com, can I use this ibis module as the module of the 200 pin SO-DIMM slot?
By the way, I just layed out a few DDR signals, can I just simulate these signals first?By other words, can I simulate signals on board first before the whole board has been layed out?
Env:Cadence SPB 15.5, layout: Allegro, simulation: specctraQuest.
Thanks from a EDA newbie!!!!
