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?

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    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.

    Resolution

    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.
