hi dude,
Decap calls r used to reduce the power bounce only (as i know).
decap cell contains Nmos Transisitors only just it acts like a reserviour .
this decap cell is charged to VDD if any power bounce occurs it gives the sufficient required voltage 4 the Cells which r placed after that Decap cell
Ground bounce is reduced by placing the more Ground I/O pads than Power pads
i dont know how it reduces the Ground bounce if any body knows explain it clearly
