    • A method for providing a capping layer configured for an energy assisted magnetic recording (EAMR) head including at least one slider. The method comprises etching a substrate having a top surface using an etch to form a trench in the substrate, the trench having a first surface at a first angle from the top surface and a second surface having a second angle from the top surface. The method further comprises providing a protective coating exposing the second surface and covering the first surface, removing a portion of the substrate including the second surface to form a laser cavity within the substrate configured to fit a laser therein, and providing a reflective layer on the first surface to form a mirror, the cavity and mirror being configured for alignment of the laser to the laser cavity and to the mirror and for bonding the laser to the laser cavity.

    • A method comprises reducing power consumption of an electronic circuit, wherein the electronic circuit comprises at least one logic cone with at least one gate having a single output net, wherein representations of the at least one gate are instances of elements from a standard cell library. Reducing of the power consumption comprises determining an upper bound for dynamic power consumption by calculating transition metrics and power metrics for each gate. Reducing of the power consumption comprises selecting gates with an upper bound for power consumption greater than a predetermined threshold value. For each selected gate, performing operations comprising: testing multiple configurations from the standard cell library for the selected gate by calculating respective upper bound for power consumption for each of the multiple configurations; selecting gate configuration with minimum upper bound for power consumption; and modifying the gate-level design representation according to the selected gate configuration.
    • 一种方法包括降低电子电路的功耗,其中电子电路包括至少一个具有至少一个具有单个输出网的门的逻辑锥,其中至少一个门的表示是来自标准单元库的元件的实例。 降低功耗包括通过计算每个门的转换度量和功率度量来确定动态功耗的上限。 降低功耗包括选择具有大于预定阈值的功耗上限的门。 对于每个所选择的门,执行操作包括:通过针对所述多个配置中的每一个计算相应的功耗上限来测试来自所选择的门的标准单元库的多个配置; 选择门极配置,最小上限为功耗; 以及根据选择的门配置修改门级设计表示。
