Impedance Matching for differential tracks

The Max 10's LVDS IO user guide mentions matching trace impedance with that of termination resistor. However in the figure given below they have mentioned single ended trace impedance of each of the ...

Thanks for replying.

@Abe​

The three resistor termination scheme needs to be employed only in case of emulated transmitter. I am more interested in the termination for a receiver and the impedance of the LVDS lines, both single ended and differential.

Sure. Will try. Any tool you recommend? Have tried Hyperlynx before but because of unavailability of IBIS models for some components other than MAX10, had to drop that idea.
