  • Publication number: 20070288875
    Abstract: A method, graphical user interface, and computer program product on a computer readable medium are disclosed for presenting a user with a display of a skew clock tree for a digital circuit design. In the preferred embodiment, a computer system receives timing analysis data for a digital circuit. The computer system determines a propagation time delay between a first clock root and each of a plurality of clock sinks of the digital circuit associated with the first clock root based on the timing analysis data. The computer system then displays the first clock root and each clock sink associated with the first clock root of the skew clock tree along an axis representing time delay. In the displayed skew clock tree, each clock sink is positioned along the axis relative to the first clock root based on each clock sink's determined propagation time delay.

  • Publication number: 20070083350
    Abstract: A method for estimating the average-case activity in a digital circuit having a clock tree, includes the steps of obtaining seed activity values at various nodes in the digital circuit using a probability-based algorithm, creating waveform traces at various nodes in the digital circuit using the seed activity values, and propagating the waveform traces through the digital circuit to find improved activity values at various nodes in the digital circuit using a simulation-based algorithm.

  • Publication number: 20070078340
    Abstract: A method and system for providing an operational command signal to a workstation of an imaging system. The workstation is provided imaging data from a positionable transducer. The method and system convert at least one of a predetermined plurality of motion patterns imparted by an operator of the system to the transducer into the operational command signal.

  • Publication number: 20060282803
    Abstract: A method for estimating the average-case activity in a digital circuit includes the steps of assigning initial activity values to outputs of flops in the digital circuit, and repeatedly updating the activity values in an iterative procedure until a predetermined termination criterion is met, wherein the updating of the activity values uses a combination of standard probability updating techniques and predetermined formulae for obtaining the activity values of predesignated types of circuit elements in the digital circuit.
