摘要： Embodiments of the inventive subject matter include determining a plurality of potential full resolution locations for a particle representation for a second iteration of a particle swarm optimization, wherein the particle representation is associated with both a first full resolution location and a first reduced resolution location for a first iteration of the particle swarm optimization that has not yet completed and the second iteration is later than the first iteration. Embodiments further include determining that the plurality of full resolution locations reduces to a second reduced resolution location for the second iteration. Embodiments further include submitting the second reduced resolution location for fitness calculation prior to the first iteration completing.

摘要： One aspect is a method that includes identifying a substantially uniform distribution of signal vias for a multi-layer circuit board based on a design file defining a layout that includes via groups in a two-to-one signal-to-ground via ratio configuration. A signal via pitch is determined as a center-to-center distance between a neighboring pair of signal vias. The signal via pitch is compared to a target minimum drilling distance. A ground via is identified proximate the neighboring pair of the signal vias. Based determining that the signal via pitch of the neighboring pair is less than the target minimum drilling distance, at least one of the signal vias is positioned closer to the ground via such that after the positioning, the signal via pitch of the neighboring pair meets or exceeds the target minimum drilling distance. The design file is modified to include the positioning of the signal vias.

摘要： One aspect includes identifying via groups that each includes a ratio of a plurality of signal vias to one ground via based on a design file defining a layout of a multi-layer circuit board. A genetic via placement solver iteratively evaluates potential placement solutions that adjust a placement of one or more of the signal vias until at least one solution is identified that meets one or more placement criteria of the signal vias. The genetic via placement solver performs a mutation and recombination of one or more solutions that do not meet the one or more placement criteria and re-evaluates the one or more solutions that do not meet the one or more placement criteria. The design file is modified to include at least one shifted signal via position based on identifying the at least one solution that meets the one or more placement criteria.

摘要： An apparatus and method may detect and reduce noise on data busses by adjusting the phase of the input/output (I/O) signals in a controlled, predictable manner. The control may allow a maximum data rate to be achieved. In one embodiment, an algorithm used to determine phase change data may be handled by a feedback loop and may be dynamically adjusted. The system may detect noise on rails and critical signals for logging in call home data. The system may maintain a database of settings as a function of a workload. The system may be used in the field as the workload changes to determine that a signal has reached a first threshold. In response to determining that the signal has reached the first threshold, an alert is initiated. A system may determine that the signal has reached a second threshold. In response to determining that the signal has reached the second threshold, the signal may be coupled to logic circuitry.
