There might not be an LVDS model in the default library. I suggest that you check with the vendor of the actual device you plan to use to see if they provide an IBIS model of that device. Another option is to find an IBIS model online of any LVDS device. ti.com has a few.
Making a good IBIS model of LVDS can be difficult, so if you get unreasonable results from an LVDS driver, try a different model. Some people know how to make these models, and some people don't.
How about using the generic_SERDES_ibs?
I found a driver model: DS90LV31ATM and a receiver model DS90LV32ATM.
I'm glad you were able to find the models you need. Thank you for taking the time to update your post! Please mark your question 'answered' by hitting the 'Correct Answer' button on your last post. Thanks!
