  • Patent number: 8549448
    Abstract: Aspect of the technology are a method of designing a circuit layout and corresponding computer systems and nontransitory computer media. The circuit layout is for use in forming a lithographic mask set for use in fabricating an integrated circuit. In the method the computer system divides a synthesized circuit design into cell partitions along critical paths of the synthesized circuit design. The computer system associates pins of the plurality of cell partitions with normalized pin timing values. The normalized pin timing values store magnitude differences between a reference timing slack and timing slacks of the plurality of pins.
    Type: Grant

  • Patent number: 5737242
    Abstract: The invention relates to a method that makes it possible to automatically and exactly calculate the probabilities associated with a Boolean function. The probability of an event represented by a Boolean function (f) is determined by constituting a binary decision diagram of the function and by making recursive traversals through the diagram.
