    • Methods, systems, and devices are disclosed for automatically generating physical layouts of integrated circuits. A circuit is partitioned into one or more cells based on a circuit description. The method further checks availability of a layout of a cell for all the cells generated during the partition step. If a layout of a cell is not available, the method generates a layout of the cell by an automatic tool, and packages the generated layout in a form of a standard cell compatible with a standard cell placement and routing tool. Afterwards, the generated layout may be exported to the standard cell placement and routing tool. Finally, the standard cell placement and routing tool may merge individual layouts of the one or more cells of the circuit to generate a layout for the circuit.
    • 公开了用于自动生成集成电路的物理布局的方法,系统和装置。 基于电路描述将电路划分成一个或多个单元。 该方法进一步检查在分区步骤期间生成的所有单元的单元布局的可用性。 如果单元格的布局不可用,则该方法通过自动工具生成单元格的布局,并以与标准单元布局和布线工具兼容的标准单元的形式打包生成的布局。 之后,生成的布局可能会导出到标准单元布局和布线工具。 最后,标准单元放置和布线工具可以合并该电路的一个或多个单元的各个布局以产生该电路的布局。

    • Methods, systems, and devices are disclosed for implementing a fiber-waveguide evanescent coupling. In one aspect, a device having integrated photonic components includes a substrate, a waveguide formed on the substrate to include a terminal waveguide portion that terminates at one side of the substrate, and a fiber including a fiber core and fiber cladding surrounding the fiber core, in which at least a portion of the fiber cladding is removed at or near a fiber terminal end to enable optical evanescent coupling via a side surface of the fiber core at the or near the fiber terminal end, the fiber core at the or near the fiber terminal end is placed over the one side of the substrate to be above and to overlap with the terminal waveguide portion of the waveguide to enable optical evanescent coupling via side surfaces of the fiber core and the waveguide.

    • Techniques, systems, and devices are disclosed for implementing a quasi-linear spin-torque nano-oscillator based on exertion of a spin-transfer torque on the local magnetic moments in the magnetic layer and precession of the magnetic moments in the magnetic layer within a spin valve. Examples of spin-torque nano-oscillators (STNOs) are disclosed to use spin polarized currents to excite nano magnets that undergo persistent oscillations at RF or microwave frequencies. The spin currents are applied in a non-uniform manner to both excite the nano magnets into oscillations and generate dynamic damping at large amplitude as a feedback to reduce the nonlinearity associated with mixing amplitude and phase fluctuations.
