My mistake, I take it back. I was thinking of something else.

As described on pg. 36-38 in the Cookbook, the data can be modeled with the [Series MOSFET], [Series Current], [R Series] keywords which have been available in the IBIS specification for years. It is a different story that not all simulators may be supporting them yet.

And if it was there is likely no simulator that would take the data anyway. You can best add that level of detail by adding an external SPICE model to the file. Use IBIS Version 4.2.

Can some IBIS experts give me more detailed information about it, or Could share some examples of LVDS IBIS file to study the format, it is still look like the single ended ibis file? how many data we need to pick? I'm really appreciated for your kindly help!
