in during floorplanning?

you can take CUP as a normal IO PAD !
( read the .lef for placement)

ya. Tell me about the internal structure of CUP and comaprision of it with simple wire bond for stress point of view.

Thanks..

HAK..

Compared to convential PAD structure, the ESD ckt is put under PAD. So the dimension of I/O pad is reduced. (because in the conventional PAD structure, the ESD ckt can't be put under PAD, so need more area for ESD ckt)
