Abstract: Fence randomization with inter-chip fencing constraints, including: receiving a fencing setup comprising one or more parameters for fencing a plurality of chips in a plurality of drawers; and selecting, based on the one or more parameters and one or more dependencies for implementing the one or more parameters, a subset of the plurality of chips for fencing, wherein the subset of the plurality of chips are selected at least partially randomly; generating a testing configuration indicating the selected subset of the plurality of chips.

Abstract: A safety drinking straw having an edge portion of at least one end folded-out and down about a circumference-defined fold-line toward the straw's outer surface and optionally sealed to that surface providing a smooth, rounded end for drinking. If desired, the folded-out portion may be stretched before being folded down toward the outer surface providing a bulbous rim-like portion to provide a wider rounded edge for drinking. The safety straw may be manufactured from paper or plastic by a molding, a spirally wound, or a glued straw stock process. Additional safety straw designs include a doughnut-like extension sealed to at least one straw end; having at least one end closed with an opening on the side of the straw near to the closed end; having a rounded edge on at least one open end; and wherein the edge perimeter of at least one end is capped by a capping portion.
