Jongbae,
Yes, it is possible to measure both Vcc and ground bounce in a package.
Your IC supplier should know how to do it. If they don't, I'd worry about
the stability of the products they design. They should be publishing the
numbers as part of their data sheets. I know that very few of them do it,
but they should. That's the reason for the huge flap over the last two
years with FPGA vendors and the ad campaign that they are running touting
how quiet their new devices are.
