Abstract
Disclosed are methods, systems and devices for distribution of a timing signal among operational nodes of a circuit device comprising one or more circuit dies. In one implementation, a timing signal distribution network may transmit a timing signal to one or more operational circuit nodes formed on a circuit die and a clock circuit may generate a first clock signal for transmission as the timing signal to the one or more operational circuit nodes. A switch circuit may apply a second clock signal for transmission as the timing signal in lieu of the first clock signal if the circuit die is integrated at least one of the one or more other circuit dies. In another implementation, timing signals received at timing signal terminals of at least two of two or more of operational circuit nodes may be synchronized independently of the timing signal distribution network.
