Hi Sunny,
Yes, R-creates the Joule heating. I have 0.44ohm on vss to clamp and 0.5 on vdd to clamp on Z layer. So, total 0.94 ohm from vdd to vss pad which I guess satisfies ESD rule (<1ohm).
1) Does this 800um (pad to pad) current path can tolerate with esd current?
2) Can we connect Bump pad sitting on IP to Internal Power mesh directly.
Below is the picture which illustrates bump placement (blue color), esd clamp placement(yellow color), Internal power mesh (Green, light Green color).

Can anybody share your experience.
Thanks in Advance.
