Abstract:
A semiconductor die includes: a clock distribution network that distributes a clock signal within the die. The clock distribution network includes: a clock tree corresponding to one or more metal layers of the die, a plurality of clock spines corresponding to a metal layer of the die, a plurality of clock wings corresponding to a metal layer of the die, a plurality of clock grid drivers placed in one or more gaps of a floorplan corresponding to the semiconductor layer of the die, a clock grid placed in the one or more gaps of the floorplan, a plurality of buffers placed in a local gain buffer pair configuration wherein the local gain buffer pair connects the clock grid to a shorting bar, and a plurality of conductors that connect the shorting bar to a plurality of loads.
