Patent attributes
Power grids of an IC are provided. A power grid includes first power traces disposed in a first metal layer and parallel to a first direction, second power traces disposed in a second metal layer and parallel to a second direction that is perpendicular to the first direction, and third power traces disposed in the first metal layer parallel to the first direction. The first power traces arranged in the same straight line are separated from each other by a plurality of first gaps. The third power traces arranged in the same straight line are separated from each other by a plurality of second gaps. Each first gap is surrounded by the two adjacent third power traces. Each second gap is surrounded by the two adjacent first power traces. The first power traces are coupled to the third power traces via the second power traces.
