Chris West has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7895555
    Abstract: Systems and methods provide improved techniques directed to simultaneous switching output (SSO) noise, which for example may be applied during the programmable logic device design process. For example in accordance with an embodiment, a method of structuring simultaneous switching output (SSO) noise data for an electronic device includes collecting hardware data on SSO noise conditions; generating additional data on SSO noise conditions based on the hardware data; and structuring the hardware data and the additional data to form data tables for SSO noise calculations.
    Type: Grant

  • Patent number: 7788620
    Abstract: Systems and methods provide I/O signal placement algorithms, such as for a programmable logic device. For example, a performing input/output (I/O) signal placement to pins of an electronic device, in accordance with an embodiment, includes placing all pre-assigned I/O signals to their assigned pin locations; placing unassigned I/O signals to initial I/O pin locations; and performing a simulated annealing for the I/O signals placed at initial I/O pin locations, wherein the simulated annealing accounts for simultaneous switching output (SSO) noise requirements.
