  • Patent number: 8826213
    Abstract: A method includes generating a three-dimensional table. The table cells of the three-dimensional table comprise normalized parasitic capacitance values selected from the group consisting essentially of normalized poly-to-fin parasitic capacitance values and normalized poly-to-metal-contact parasitic capacitance values of Fin Field-Effect Transistors (FinFETs). The three-dimensional table is indexed by poly-to-metal-contact spacings of the FinFETs, fin-to-fin spacings of the FinFETs, and metal-contact-to-second-poly spacings of the FinFETs. The step of generating the three-dimensional table is performed using a computer.

  • Patent number: 8572537
    Abstract: A system and method for extracting the parasitic contact/via capacitance in an integrated circuit are provided. Parasitic extraction using this system can lead to an improved accuracy on contact/via parasitic capacitance extraction by taking into account of the actual contact/via shape and size variation. The common feature of the various embodiments includes the step of generating a technology file, in which the contact/via capacitance in the capacitance table is derived from an effective contact/via width table. Each element of the effective contact/via width table is calibrated to have a parasitic capacitance matching to that of an actual contact/via configuration occurring in an IC.

  • Publication number: 20130174112
    Abstract: A method of generating a bias-adjusted layout design of a conductive feature includes receiving a layout design of the conductive feature. If a geometry configuration of the layout design is within a first set of predetermined criteria, the bias-adjusted layout design of the conductive feature is generated according to a first layout bias rule. If the geometry configuration of the layout design is within a second set of predetermined criteria, the bias-adjusted layout design of the conductive feature is generated according to a second layout bias rule.

  • Patent number: 7181664
    Abstract: A method for reordering a scan chain meets given constraints and minimizes peak power dissipation. The given constraints include a maximum peak power dissipation, a maximum scan chain length and a maximum distance between two successive registers. The method includes embedding a developed tool into an existing VLSI design flow for low-power circuit designs. Furthermore, the characteristics quickly judge if the problem has corresponding feasible solutions and searching the optimal solution. Modified data from the given scan chain declaration data and the scan pattern data, which satisfy the constraints, can be obtained.
