Is there a problem with the accuracy of the LVDS input with differential on-chip termination (OCT) IBIS model of  Intel® Stratix® 10, Intel Arria® 10 and Intel Cyclone® 10 GX devices?

Description

Yes, there is a problem with the accuracy of the LVDS input with 100 Ohm on-chip termination (OCT) IBIS model, for Intel® Stratix® 10,  Intel Arria® 10 and Intel Cyclone® 10 GX devices.

Workaround/Fix

During IBIS simulation, add an external 100 ohms differential termination near to the input IBIS model in order to simulate the worst case scenario of a LVDS input with OCT of 100 Ohms enabled.
