  • Patent number: 10552570
    Abstract: A method, system, and computer product for performing a coupled noise analysis in an integrated circuit (IC) design include copying one or more victim circuit sections of a victim circuit in the IC, generating a blockage circuit section that represents a blockage aggressor circuit in the IC, using the copied one or more victim circuit sections of the victim circuit, determining at least one subcircuit from the blockage circuit section, selecting, for a victim pin on the victim circuit, a power-driven virtual node on the at least one subcircuit, applying a power source to the power-driven virtual node on the at least one subcircuit, calculating a coupled noise at the victim pin contributed by the at least one subcircuit in response to the power source being applied, comparing the coupled noise to a threshold noise level, and altering the IC design when the coupled noise exceeds the threshold noise level.

  • Publication number: 20080272048
    Abstract: A filter cartridge comprises a pleat pack including filtration media for removing particulates from a particulate laden fluid stream moving in a first direction through the filtration media. The pleat pack is formed into a tubular configuration with a plurality of circumferentially spaced pleats. The filtration media is periodically subject to a cleaning fluid stream moving in a second direction opposite to the first direction. Potting material is at axially opposite end portions of the pleat pack to maintain the filtration media in the tubular configuration. A support tube is located on a first side of the pleat pack downstream of the filtration media in the first direction of fluid flow. A retention device limits movement of a portion of the filtration media when subjected to the periodic cleaning fluid stream. The retention device comprises a metal band and located on a second side of the filtration media opposite the first side.
