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.

You can also enable it using command as below in QSF file 

 

set_instance_assignment -name WEAK_PULL_UP_RESISTOR ON -to *
