MAX V add pull up resistor for input

Hi Guys,

I'm not sure how to add a pull up resistor for an input pin using Quartus Prime?

I try to find it in Pin planner and assignment, but there is nothing shows to add a pull up resistor.

Thanks!

    Right, the weak pull-up column need to be enabled before in the right mouse-button "customize columns" context menu.
