Hi,
I am using TPS650250 in my design to power ARTIX-7. The ouput from DCDC2 required is 1.8V. I have two options to select this. Either use resister divider network or ground the DEFDCDC2 pin. Which one is preferred and correct option.

Connect DEFDCDC2 directly to GND. This saves you 2 resistors on the BOM and reduces overall area of the solution size.
