I would like to know the BF70x IBIS model include ODT feature or not?
If not, how to simulate PCB design include ODT feature?
Thank you for your help in advance.
BF70x IBIS file seems not include ODT simulation group data.
Do you have a plan to release IBIS file that support ODT feature?
The IBIS model does not support ODT, the processor does. Board designer has to put two resistors one connected to IOVDD other to ground in the SI simulations. For example - for 75 ohm ODT the two resistors need to be 150Ohm each. You may also want to investigate whether ODT is required at all on your board. At 200MHz DDR speed it's not a strict requirement but whether to use it or not does depend on the board in question. Not having ODT does save significant power.
Hello, Jithul san,
Thank you for your response!
I understood that.
