  • Patent number: 8910107
    Abstract: Various embodiments identify a design including circuit features and identify an operation that produces an aggressor for victim(s). The operation on the aggressor and the set of victims are implemented using local maximally spanning spacetile(s) while satisfying some design requirements. Where the set of victims includes interconnects, the design may allow no bend in some interconnects. One or more spacetiles are used to perform the operation on the aggressor and implement the interconnects while introducing no bends in the interconnects by using local maximally spanning spacetile(s). Some implementation may perform block modeling for the aggressor to perform the operation on the aggressor and implement a set of victims while preserving the relative order of the interconnects by using the block modeling for the aggressor.

  • Patent number: 8640080
    Abstract: Disclosed is a method and system for visualizing pin access locations on an integrated circuit design. Visual feedback is provided to a user that is attempting to connect a wire or a via to a pin structure polygon on the integrated circuit design. The visual feedback comprises any visual cue that provides an indication of a legal location to access the pin.

  • Patent number: 8320542
    Abstract: Methods and systems provided telephone accessible services to callers which are responsive to information about the caller obtained during the call. A telephone service point located anywhere within the telephone network receives a telephone call to particular numbers referred to as hypernumbers and provides services specified for the dialed number. The service point may request data from the caller's communication device and provide services or route the call in response to caller-specific information received from the communication device. Caller communication devices may be configured with software to communicate with the service point, including gathering requested caller information and transmitting the information to the service point. The service point may be configured to send information to the caller's communication device. The service point may be configured to send caller data to a server of the hypernumber owner and route the call to particular destinations based upon the caller data.

  • Patent number: 6601226
    Abstract: A tightloop method of timing driven placement. The present invention interleaves timing analyses and updates net weight based on the timing analyses as part of the cell location refinement processes of a placement algorithm. Thereby, the placement algorithm is augmented to factor in timing information such that the final placement is effective from overlap, net length, and timing perspectives.
