Abstract: A system for mitigating power supply and power distribution system noise response by throttling execution units based upon voltage sensing in a circuit is provided. A sensing unit senses the voltage of a circuit. The sensing unit determines if the execution of another execution unit will cause the circuit voltage to drop below a threshold level. In response to a determination that the execution of another execution unit will cause the circuit voltage to drop below the threshold level, the execution unit is throttled.

Abstract: An auto routing method and system provides optimized circuit routing while maintaining proper reference return paths for critical signals. Critical signal paths are auto-routed simultaneously with corresponding reference return paths, and the reference return paths can be merged into reference planes if they are adjacent to regions connected to the same reference net. The reference return paths may be in a plane adjacent to the signal path plane in the same channel, or the reference returns may be routed in adjacent channels in the same plane as the signal path. A check may be performed on endpoints of each critical signal path to determine whether a reference return via is present within a proximity tolerance of the signal path endpoints, and a reference return via placed if not.

Abstract translation: 自动路由方法和系统提供优化的电路路由，同时为关键信号保留适当的参考返回路径。 临界信号路径与对应的参考返回路径同时自动路由，并且如果参考返回路径与连接到相同参考网络的区域相邻，则它们可以合并到参考平面中。 参考返回路径可以在与相同信道中的信号路径平面相邻的平面中，或者参考返回可以在与信号路径相同的平面中的相邻信道中路由。 可以在每个关键信号路径的端点上执行检查，以确定参考返回通道是否存在于信号路径端点的接近容限内，如果不是则通过放置参考返回。

Abstract: A circuit and a method for detecting noise events in a system with time variable operating points is provided. A switched capacitor filter comprising a plurality of capacitor units, samples a first voltage to determine an average of a set of voltage measurements, forming an average voltage. A filter control unit controls the plurality of capacitor units in the switched capacitor filter. A comparing unit compares the average voltage to the first voltage to form a comparison. A signaling unit generates a signal to instruct circuits in a processor to initiate actions to keep the first voltage from drooping below a threshold level in response to the comparison.

Abstract: A system for minimizing the length of the longest diagonal interconnection. A multiple chip module may comprise a first chip connected to a second chip located diagonally to the first chip. The first and second chip are interconnected by one or more interconnections commonly referred to as diagonal interconnections. Since the one or more diagonal interconnections between the first chip and the second chip are interconnected between a set of pins on each chip that form a triangular pattern, the longest diagonal interconnection is substantially the same length as the length of the longest orthogonal interconnection. Furthermore, since the one or more diagonal interconnections between the first chip and the second chip are interconnected between a set of pins on each chip that form a triangular pattern, the longest diagonal interconnection is substantially the same length as the length of the second longest diagonal interconnection.

Abstract: A first selection of mesh line segments of a mesh layer are of a first width and a second selection of mesh line segments of the mesh layer are of a second width, wherein the second width is greater than the first width. The second selection of mesh line segments of the second width are positioned in parallel to a selection of signal lines in a signal layer that are likely to introduce crosstalk, wherein the widening of the mesh line segments shadowing the selection of signal lines increases the likelihood that the return current associated with the signal will flow in the wider mesh line segment, thereby increasing the likelihood of containing the electromagnetic fields associated with the signal such that crosstalk to other signals is reduced or contained.
