Abstract: The present invention provides a process for constrained clock skew scheduling which computes for a given number of clocking domains the optimal phase shifts for the domains and the assignment of the individual registers to the domains. For the within domain latency values, the algorithm can assume a zero-skew clock delivery or apply a user-provided upper bound. Experiments have demonstrated that a constrained clock skew schedule using a few clocking domains combined with small within-domain latency can reliably implement the full sequential optimization potential to date only possible with an unconstrained clock schedule.
