    摘要: A method includes approximating a physical characteristic of a semiconductor substrate with a frequency-dependent circuit, and creating a technology file for the semiconductor substrate based on the frequency-dependent circuit. The physical characteristic of the semiconductor substrate identified by one of an electromagnetic simulation or a silicon measurement. The technology file is adapted for use by an electronic design automation tool to create a netlist for the semiconductor substrate and is stored in a non-transient computer readable storage medium.

    摘要: A method includes providing a layout of an integrated circuit design, and generating a plurality of double patterning decompositions from the layout, with each of the plurality of double patterning decompositions including patterns separated to a first mask and a second mask of a double patterning mask set. A maximum shift between the first and the second masks is determined, wherein the maximum shift is a maximum expected mask shift in a manufacturing process for implementing the layout on a wafer. For each of the plurality of double patterning decompositions, a worst-case performance value is simulated using mask shifts within a range defined by the maximum shift. The step of simulating the worst-case performance includes calculating capacitance values corresponding to mask shifts, and the capacitance values are calculated using a high-order equation or a piecewise equation.

    摘要: A method includes extracting a first netlist from a first layout of a semiconductor circuit and estimating layout-dependent effect data based on the first netlist. A first simulation of the semiconductor circuit is performed based on the first netlist using an electronic design automation tool, and a second simulation of the semiconductor circuit is performed based on a circuit schematic using the electronic design automation tool. A weight and a sensitivity of the at least one layout-dependent effect are calculated, and the first layout of the semiconductor circuit is adjusted based on the weight and the sensitivity to provide a second layout of the semiconductor circuit. The second layout is stored in a non-transient storage medium.
