Abstract: Described is an apparatus for over-clocking or under-clocking, the apparatus comprises: a locked loop (e.g., phase locked loop or frequency locked loop) having a feedback divider, the locked loop to receive a reference clock and to compare it with a feedback clock which is output from the feedback divider, and to generate an output clock; a post locked loop divider, coupled to the locked loop, to receive the output clock and to generate a base clock for other logic units; and a control logic to adjust first and second divider ratios for the feedback divider and the post locked loop divider respectively for over-clocking or under-clocking the base clock such that the locked loop remains locked while being over-clocked or under-clocked.

Abstract: Described is an integrated circuit (IC) with a phase locked loop with capability of fast locking. The IC comprises: a node to provide a reference clock; a digitally controlled oscillator (DCO) to generate an output clock; a divider coupled to the DCO, the divider to divide the output clock and to generate a feedback clock; and control logic operable to reset the DCO and the divider, and operable to release reset in synchronization with the reference clock. An apparatus for zeroing phase error is provided which comprises a first node to provide a reference clock; a second node to provide a feedback clock; a time-to-digital converter, coupled to the first and second nodes, to measure phase error between the reference and feedback clocks; a digital loop filter; and a control unit to adjust the measured phase error, and to provide the adjusted phase error to the digital loop filter.

Abstract: Disclosed herein are swizzling techniques that may provide capacitive and inductive noise cancellation on a set of signal lines. Positive noise due to a capacitive coupling between attacker signal lines and near victim signal lines is, in part, cancelled by negative noise due to inductive coupling between the attacker signal lines and a far victim signal line. Swizzling patterns and repeatable swizzling patterns are computed to transpose near victim signal lines and far victim signal lines in subsequent segments to facilitate the capacitive and inductive cancellation. The signal lines are optionally reordered by computing a final swizzling to restore the set's original ordering.

Abstract: A method and system for determination of the worst case switching vector, which greatly reduces the search space complexity. A single simulation is performed in the time-domain wherein the roles of the victim and attacker conductors are switched. In particular, the search space is reduced by virtue of the fact that certain combinations for the behavior attacker conductors are excluded. Only the phases of the attacker signals need to be determined.
