A semiconductor device a first power pad, a second power pad, a first power network,
and a second power network. The first power pad is operable to supply a first potential,
and the second power pad is operable to supply a second potential. The first power
network defines a first periphery in the semiconductor device and is coupled to
the first power pad and the second power pad. The second power network defines
a second periphery in the semiconductor device and is coupled to the first power
pad and the second power pad.
