1. An apparatus, comprising:
an integrated circuit having a clock network in an array of circuit blocks; wherein the clock network includes routing tracks, distribution spines, and clock leaves; wherein a set of the leaves is coupled to a horizontal distribution spine of the distribution spines within a circuit block of the circuit blocks for providing a clock signal from the horizontal distribution spine to the set of the leaves; wherein an interconnect tile is configured for local gating for providing the clock signal to the set of the leaves without going through the horizontal distribution spine; and wherein the routing tracks and the distribution spines are bidirectional.
