摘要： Figures of merit by actual design parameters are tracked over iterations for candidate solutions that include both actual design parameters and actual context parameters. Instead of returning a current iteration figure of merit, a worst observed figure of merit for a set of actual design parameters is returned as the figure of merit for a candidate solution. Since the candidate solution includes both actual design parameters and actual context parameters and the worst observed figures of merit are tracked by actual design parameters, the figure of merit for a set of design parameters will be the worst of the observed worst case scenarios as defined by the actual context parameters over a run of a metaheuristic optimizer.
摘要翻译：根据实际设计参数的实际设计参数和实际上下文参数的候选解决方案的迭代跟踪实际设计参数的数据。不是返回当前的迭代品质因数，而是返回一组实际设计参数中最差的品质因数作为候选解决方案的品质因数。由于候选解决方案包括实际设计参数和实际上下文参数，并且通过实际设计参数跟踪最差的观察到的品质因数，一组设计参数的品质因数将是最差的观察到的最坏情况，如在元启发优化器的运行中的实际上下文参数。

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： An apparatus and method for detecting transient voltage at an electrical component of a circuit board is provided. The apparatus including a circuit including a comparator and a latch, wherein a first input of the comparator is electrically coupled to the electrical component, and the comparator receives a threshold voltage at a second input, where the comparator outputs either a high signal or a low signal in response to both the first input and the second input, and an output of the comparator is electrically coupled to an input of the latch such that the latch outputs a high signal in response to receiving a high signal from the comparator, and an indicator electrically coupled to an output of the latch, and where the apparatus is mounted non-permanently to the circuit board to provide a non-permanent electrical coupling between the comparator and the electrical component.

摘要： An apparatus includes a carrier base and one or more contact elements coupled to a portion of the carrier base. The one or more contact elements are configured to sense an electrical signal flowing through at least one electrical component in a circuitry under test. The first contact element of the one or more contact elements comprises a power sense conductor extending from a bottom surface of the first contact element toward a top surface of the first contact element and a ground conductor electrically isolated from the power sense conductor.

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： 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.
