  • Patent number: 10402525
    Abstract: The described techniques implement an electronic design with transistor level satisfiability models by identifying a plurality of channel connected components of an electronic design for sensitization. These techniques further determine a set of transistor level satisfiability (SAT) models for the plurality of channel connected components of the electronic design and transform the plurality of channel connected components into a set of conjunctive normal form (CNF) formulae using at least the set of transistor level SAT models. The plurality of channel connected components of the electronic design may be sensitized at least by determining one or more satisfying assignments with the set of CNF formulae. These techniques may also generate transistor level satisfiability (SAT) logic models and transistor level SAT state models for a circuit component based in part or in whole upon design specifications and one or more characteristics of the circuit component.

  • Patent number: 9594858
    Abstract: Various embodiments scalable statistical library characterization for electronic designs by identifying an electronic design, performing circuit simulations on strongly connected components on a component-by-component basis, performing the logic cone analysis on the entire electronic design, and performing combinations of influences on the electronic design caused by variations of parameters. Some embodiments perform simulations on one or more stronger parameters or the strongest parameter of a circuit component and use the simulation results to calibrate the predicted behaviors of one or more remaining circuit components of the electronic design. Various statistical or mathematical techniques may be used for performing the combinations of influences on the electronic design caused by variations of parameters. The techniques described are scalable with the increase in complexities and sizes of electronic designs while reducing or minimizing the impact on sensitivity accuracy.

  • Patent number: 7363605
    Abstract: A method for analyzing a circuit design identifies a possible noise fault for a timing interval based on a timing analysis of a victim net and at least one aggressor net of the circuit design and determines whether the noise fault is feasible based on a behavioral representation of the victim net and the aggressor net for the timing interval.

  • Publication number: 20050256235
    Abstract: The present invention relates to environmentally sensitive organic binders stabilized by maleic anhydride and its derivatives. The unstabilized binders can rapidly hydrolyze and thicken when exposed to the environment, and especially to moisture. Maleic anhydride and its derivatives act to stabilize these binders. The stabilized organic binders of the invention are especially useful for forming marine antifoulant coatings.

  • Publication number: 20050255081
    Abstract: The present invention relates to triorgano phosphites, triorgano amines, heteroaromatic nitrogen compounds, and carbodiimides used as stabilizers for hydrolyzable organic binders. The stabilizers help to prevent viscosity thickening of polymeric binders containing carboxylic ester groups. Without stabilization, the binders can rapidly thicken when exposed to moisture air. The stabilized organic binders of the invention are especially useful for formulating marine antifoulant coatings.

  • Patent number: 6836873
    Abstract: Static noise analysis simulates crosstalk functional noise by estimating a crosstalk functional noise window and by calculating the propagation of the noise window through a network. For example, the analysis can include simulations of injecting a noise window onto a network, propagating the noise window through the network until it reaches a register, and comparing the noise window with a register's sensitive window. The noise window for the net is calculated based on a duration of time in which noise glitches caused by capacitive coupling to aggressor nets can occur. The noise window is propagated through the net in a forward direction until the noise is attenuated or reaches a register's input. At the register's input, a sensitive window can filter the noise window so that only the portion of the noise window that coincides with the register's clock trigger time is considered in the noise analysis.
