  • Patent number: 7480888
    Abstract: A design structure embodied in a machine-readable medium is disclosed in one embodiment of the invention as including a flexible logic block to facilitate engineering changes at selected locations within an IC. The flexible logic block has a consistent and identifiable structure such that a simple automated process may be used to reconfigure the structure to perform different logical operations. In certain embodiments, the flexible logic block includes a circuit, such as a multiplexer, having multiple inputs and at least one output. A metal interconnect structure is coupled to the inputs and enables connection of each of the inputs to one of several electrical potentials using a focused-ion-beam (FIB) tool. In this way, the circuit may be configured to perform different logical operations after components in the IC exist in hardware.

  • Patent number: 7302673
    Abstract: A method for reticle design correction and electrical parameter extraction of a multi-cell reticle design. The method including: selecting a subset of cell designs of a multi-cell reticle design, each cell design of the subset of cell designs having a corresponding shape to process, for each cell design of the subset of cell designs determining a respective cell design location of the corresponding shape; determining a common shapes processing rule for all corresponding shapes of each cell design based on the respective cell design locations of each of the corresponding shapes; and performing shapes processing of the corresponding shape only of a single cell design of the subset of cell designs to generate resulting data for the subset of cell designs. Also a computer usable medium including computer readable program code having an algorithm adapted to implement the method for reticle design correction and electrical extraction.

  • Patent number: 6023567
    Abstract: An automated process for timing rule verification for an integrated circuit design is disclosed. The process includes the step of checking the generated timing rules by comparing a given timing rule against a synthesized model to determine timing relationships in the model that are not included in the timing rule and timing relationships in the timing rule that are not present in the model.
