ABSTRACT:
Clock distribution circuitry for a structured ASIC device includes a deterministic portion and configurable portions. The deterministic portion employs a predetermined arrangement of conductor segments and buffers for distributing a clock signal to a plurality of predetermined locations on the device. From each predetermined location, an associated configurable portion of the clock distribution circuitry distributes the clock signal to any clock utilization circuitry needing that clock signal in a predetermined area of the structured ASIC that is served from that predetermined location.
