ChipScope IBERT - Why is the RX Sampling Slider grayed out?

Description

When I try to change the RX sampling point, I see the slider is grayed out and cannot be moved.

The horizontal eye scan feature on the Sweeping cannot be used either.

Solution

The horizontal scan is supported only when PLL_RXDIVSEL_OUT is set to 1.

This is a general restriction on transceivers.
