ABSTRACT:
The invention provides for the arrangement and management of timing of various domains on a large integrated circuit which introduces a phase offset between clock domains of neighboring cells to create a wavefront clock which propagates through the circuit at the same speed data propagates though the circuit. The cells of the integrated circuit are wavefront clock synchronized in that the phase offset introduced in a particular cell's clock is such that the arrival of a skewed clock and propagation delayed data from that cell's neighbor is synchronized with that particular cell's own clock. Wavefront clock synchronization mitigates at least some of the problems of clock skew and the associated effects of slowing data propagation and reduction of clock frequencies associated with large surface integrated circuits utilizing synchronized clock domains.
