    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: 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.
