How to solve error "174077:on chip termination control block is associated with conflicting I/OS"?

I am trying to design ddr3 interface using Qsys in Quartus Prime Lite Edition for cyclone V GT (5CGTFD9E5F35C7) Development board. While running I/O assignment analysis, I am facing this error. I am not able to understand what causing this error and what should be done in order to solve it .

    Did you run the pin_assignments.tcl script generated by the memory IP? This creates the correct I/O assignments for the interface.

    Which is correct, you need to run the tcl scripts. Only arria 10 and S10 you do not need to run the tcl scripts.
