  • Method and system for implementing parallel processing of electronic design automation tools
    Patent number: 7904852
    Abstract: Disclosed is an improved method and system for processing the tasks performed by an EDA tool in parallel. The IC layout is divided into a plurality of layout windows and one or more of the layout windows are processed in parallel. Sampling of one or more windows may be performed to provide dynamic performance estimation.
    Type: Grant
    Filed: September 12, 2005
    Date of Patent: March 8, 2011
    Assignee: Cadence Design Systems, Inc.
    Inventors: Eitan Cadouri, Krzysztof A. Kozminski, Haifang Liao, Kenneth Mednick, Roland Ruehl, Mark A. Snowden

  • Thermally coupled information transmission across electrical isolation boundaries
    Patent number: 4757528
    Abstract: An electro-thermal isolator coupler including a pair of electrically isolated thermal receivers specifically spaced from an electrically isolated thermal transmitter such that their combined signals will produce a thermally compensated electrical output. A second pair of electrically thermal receivers is included in an error circuit which corrects the driver of the thermal transmitter for losses across the thermal coupler. Depending upon the use, the thermal coupler can be used in combination with RF capacitive coupling. Individual power terminals for the electrically isolated regions assure electric isolation.
