  • Publication number: 20180373830
    Abstract: A method of performing transistor simulation with improved sensitivity to parasitic by model order reduction in transistor-level timing is disclosed. The method includes reducing a number of derivative calculations during transistor simulation by representing parasitics as a reduced-order model, wherein the reducing includes: compressing the parasitics to a reduced-order model; simulating with load which is replaced with the reduced-order model; differentiating results of the simulation with respect to reduced-order model parameters; differentiating parameters of the reduced-order model with respect to parasitic values; differentiating the parasitic values with respect to statistical parameters; and computing the differential results of the simulation with respect to the statistical parameters via chain ruling.

  • Publication number: 20170313540
    Abstract: A collation folding device comprising one or more fold rollers mounted in fixed positions. Below and adjacent to the fold rollers are adjustable nip rollers to form nip spacing between the rollers. The adjustable nip roller is mounted on a nip axis shaft. An adjustment mechanism is used for moving the nip axis shaft to adjust the nip spacing. The nip adjustment mechanism includes a bearing block cam follower on which the nip axis shaft is fixedly mounted and supported. An eccentric cam in operative contact with the bearing block cam follower. Rotation of the eccentric cam on the eccentric cam axis drives the bearing block cam follower in its linear motion to adjust the nip spacing.

  • Publication number: 20170206294
    Abstract: Embodiments relate to multi-cycle signal identification for static timing analysis. An aspect includes identifying, in a circuit under test, a multi-cycle signal, the multi-cycle signal having a longer period than a main clock signal of the circuit under test. Another aspect includes mapping a plurality of additional signals of the circuit under test onto the multi-cycle signal, the plurality of additional signals each having a shorter period than the multi-cycle signal. Yet another aspect includes performing static timing analysis of the circuit under test based on the multi-cycle signal.

  • Patent number: 9684758
    Abstract: One or more processors group a plurality of timing arcs into a plurality of equivalence classes. Each timing arc includes one or more delay tables. One or more processors generate, for at least one equivalence class of the plurality of equivalence classes, an average sensitivity to a condition by performing a weighted average on respective sensitivities of timing arcs to the condition. One or more processors determine a sensitivity of an electronic circuit to the condition based, at least in part, a match between one or more attributes of the electronic circuit and one or more attributes present in the at least one equivalence class.

  • Publication number: 20160364519
    Abstract: Examples of techniques for analyzing and generating timing reports for circuits are described herein. A computer-implemented method includes splitting a netlist or cross section of a circuit into sub-circuits. The method further includes building a timing graph by combining generated timing models of the sub-circuits. The method includes determining a full set of dependencies based on each sub-circuit's dependent configuration parameters. The method also further includes generating a sample plan for each sub-circuit. The method includes receiving results from a simulation for each sub-circuit based on the sample plan for each sub-circuit. The method includes generating algebraic forms for an early delay, a late delay, and a slew by curve fitting across the configuration parameters. The method includes propagating arrival times and slew in algebraic forms throughout the timing graph. The method includes evaluating checks based on selected projections from the timing graph to find a worst slack configuration.

  • Patent number: 9357766
    Abstract: A perfusion apparatus including a perfusion circuit that perfuses an organ or tissue has a compartment that supports an organ or tissue during perfusion, an internal cover, and an external cover that closes the apparatus. A wall portion may extend substantially perpendicularly between the internal cover and the external cover to define a document compartment between the internal cover, the external cover and the wall portion. A tamper evident seal will not permit the external cover to open without creating a record of whether the external cover has been opened after the tamper evident seal has been activated.
