Hi
insert the PAD in netlist!
But bestly, make module of top level, where the PADs and your module will connect.

Hi ,

Instantiation of PAD in RTL is better .

1) It gives opertunity to do functional simulation
2) BSD ( Boundary scan design ) better you do in RTL .


Better if you make RTL partition such that your core in separate and pad control separate .
