  • Publication number: 20150227664
    Abstract: There is described a method of optimizing the design of an electronic device with respect to electromagnetic emissions based on frequency spreading. With the method, a designer can, for example, perform a transient simulation on the device only once, and then add frequency spreading with specific parameters by simulation. The resulting frequency spread signal can be observed. The designer can thus evaluate the reduction in electromagnetic emission level, and repeat this process by iteratively applying frequency spreading each time with specific parameters but without having to modify the schematic of the device and to perform another simulation of the device. The method according to this innovation is extremely rapid as the simulation of the design does not need to be repeated at each run of the frequency spreading simulation.

  • Publication number: 20150227663
    Abstract: There is described a method of optimizing the design of an electronic device with respect to electromagnetic emissions based on frequency spreading. With the method, a designer can, for example, perform a transient simulation on the device only once, and then process the obtained signal data to add frequency spreading with specific parameters by post-processing. The resulting data can be filtered by various methods and the resulting spectrum observed. The designer can thus evaluate the reduction in electromagnetic emission level, and repeat this process by iteratively applying frequency spreading each time with specific parameters but without having to modify the schematic of the device and to perform another simulation of the device. The post-processing according to this innovation is extremely rapid as it is not a simulation process such as SPICE™, ADS™, etc. Only data is manipulated.

  • Patent number: 9104478
    Abstract: A method of processing a job is presented. A packet selector determines a candidate job list including an ordered listing of candidate jobs. Each candidate job in the ordered listing belongs to a communication stream. Jobs in the candidate job list that are eligible for execution are identified by determining whether a preceding job belonging to the same communication stream as the candidate job is present in the candidate job list, and, for each candidate job in the candidate job list, determining whether a preceding job belonging to the same communication stream as the candidate job is being prepared for execution. The packet selector determines a priority for each eligible candidate job in the candidate job list by at least comparing the communication stream of each candidate job to a communication stream of a first job executing within the data processor.

  • Patent number: 9104826
    Abstract: A design verification system automatically identifies coverage of different constraints for a static model of an electronic device. The static model can be employed by a tool, referred to as a solver, that identifies whether the mathematical relationships of the static model can be reconciled, given a set of user-defined constraints that indicate a desired configuration, or range of configurations, of the electronic device. After a solution for a particular set of user-defined constraints has been identified, a constraints adjustment module can identify, based on coverage information generated by the solver, if other sets of user-defined constraints were implicitly solved by the solver. If such other sets were implicitly solved, the adjustments module can mark the sets as solved, such that they will omitted from constraints used for subsequent solutions of the solver.

  • Patent number: 9105657
    Abstract: Adverse tradeoff between BVDSS and Rdson in LDMOS devices employing a drift space adjacent the drain, is avoided by providing a lightly doped region of a first conductivity type (CT) separating the first CT drift space from an opposite CT WELL region in which the first CT source is located, and a further region of the opposite CT (e.g., formed by an angled implant) extending through part of the WELL region under an edge of the gate located near a boundary of the WELL region into the lightly doped region, and a shallow still further region of the first CT Ohmically coupled to the source and ending near the gate edge whereby the effective channel length in the further region is reduced to near zero. Substantial improvement in BVDSS and/or Rdson can be obtained without degrading the other or significant adverse affect on other device properties.
