Abstract:
An integrated circuit including a power distribution system, the integrated circuit comprising:a plurality of symmetrical power distribution structures associated with the power distribution system and distributed across at least a portion of a surface of the integrated circuit; a plurality of circuit blocks coupled for receiving power through one or more of the plurality of power distribution structures; and wherein: (a) each of the plurality of power distribution structures comprises: (a1) a first power line for providing a first power supply voltage; and (a2) a second power line and a third power line for providing a second supply voltage, wherein the second power line and the third power line are disposed symmetrically on opposite sides of the first power line; (b) the first power line and second power line are substantially parallel; (c) the second power line and the third power line each substantially has a width w and the first power line has a width equal to about twice the width w; and (d) the plurality of power distribution structures are spaced substantially evenly across the portion of the surface.
