Hi,

Generally the best way is to study very carefully the document which comes with the design kit. Most of the time the document includes whatever you need ...

designing your own I/O and ESD? Or using foundry provided?

RTFM if foundry provided. Contact foundry support.

If you have access to IBM, then they have a whole host of documentation and examples. Also, I have found that their foundry tech support can be quite helpful as well.

That aside, I/O rings are usually concerned about a few things :-
a) ESD protection
b) RF pads (lower parasitic, weaker protection diodes ...)
c) Clamp cells and latchup
d) Analogue to digital stitch up/isolation
e) Power distribution (voltage drops and current handling)

If you cover all of the above, you're in great shape.
