    摘要: A method of analyzing and designing circuits comprising creating a set of interpolated models for transistor devices; creating a set of characterized (direct fit) models for the transistor devices; analyzing the transistor devices within a netlist for matches in the set of characterized models; and providing a choice of using the matched characterized models or one of the interpolated models in designing the circuits. The method further comprises schematically simulating a custom circuit; back annotating to a schematic circuit which of the transistors use direct-fit models and which of the transistor devices are interpolated; determining whether the transistor devices are in any of cutoff, saturation, static linear, and dynamic linear mode during simulation of the custom circuit; removing the saturation and dynamic linear mode transistor devices; back annotating the netlist to a schematic with a predetermined device state; and performing sensitivity analysis on saturation and dynamic linear mode transistor devices.

    摘要: A method for altering circuit characteristics to make them independent of processing parameters of devices within an integrated circuit is disclosed. A process parameter is measured by a kerf or on-chip built-in test on a selective set of chip on a wafer, and the results are stored on a storage device within each respective chip. Then, for each of the remaining chips, a two-dimensional interpolation is performed to determine the process parameter value for the respective chip based on the measured value. The interpolated values are recorded along with the coordinates of the chip in an efuse control file. Such information is subsequently stored into an efuse module within the chip. On-chip digital control structures are used to adjust certain operational characteristics of a functional component within the chip based on the information stored in the efuse module.

    摘要: A method for converting globally clock-gated circuits to locally clock-gated circuits is disclosed. A timing analysis is initially performed on an integrated circuit (IC) design to generate a slack time report for all globally clock-gated circuits within the IC design. Based on their respective slack time indicated in the slack time report, all globally clock-gated circuits that should be connected to locally generated clocks are identified. After disconnecting from a global clock tree, each of the identified globally clock-gated circuits is subsequently connected to a locally generated clock having a clock delay comparable to its slack time indicated in the slack time report.
