Bisection methodology for on-chip variation tolerant clock signal distribution in an integrated circuit

Abstract:

A clock distribution component may include a plurality of electrically connected buffer pair triads arranged in a plurality of levels. A buffer pair triad, of the plurality of buffer pair triads, may include three buffer pairs that are connected via wire. Each buffer pair triad may share at least one buffer pair with one or more buffer triads of the plurality of buffer pair triads. Buffer pairs, of the plurality of buffer pair triads, may be arranged in buffer rows and buffer columns. The plurality of levels may include a first level associated with a first buffer pair triad and one or more additional levels. Each level of the one or more additional levels may include at least three buffer pair triads and at least two more buffer pair triads and/or at least two less buffer pair triads than an adjacent level of the one or more additional levels.
