  • Patent number: 9201107
    Abstract: A method for cell characterization with Miller capacitance includes characterizing input capacitance of an input of a first stage in a cell by considering a first current transition at the input of the first stage up to a first stop time. The first stop time occurs during the first current transition exhibits a substantial tail portion contributed by the later of a first input voltage transition and a first output voltage transition reaching a corresponding steady state voltage. The first input voltage transition is associated with the input of the first stage. The first output voltage transition is associated with an output of the first stage coupled to the input through a capacitor.

  • Publication number: 20150331990
    Abstract: A method of forming a semiconductor arrangement is provided. The semiconductor arrangement includes an interconnection arrangement comprising a first connection between a driver and a receiver. At least one buffer is disposed along the first connection to reduce delay associated with the interconnection arrangement. However, buffers increase power consumption, and thus a determination is made as to whether a buffer is unnecessary. A buffer is determined to be unnecessary where removal of the buffer does not violate a timing constraint regarding an amount of time a signal takes to go from the driver to the receiver. If a buffer is determined to be unnecessary, the buffer is removed to reduce power consumption.

  • Publication number: 20150302128
    Abstract: In some embodiments, in a method, placement of a design layout is performed. The design layout includes a power rail segment, several upper-level power lines and several cells. The upper-level power lines cross over and bound the power rail segment at where the upper-level power lines intersect with the power rail segment. The cells are powered through the power rail segment. For each cell, a respective current through the power rail segment during a respective SW of the cell is obtained. One or more groups of cells with overlapped SWs are determined. One or more EM usages of the power rail segment by the one or more groups of cells using the respective currents of each group of cells are obtained. The design layout is adjusted when any of the one or more EM usages of the power rail segment causes an EM susceptibility of the power rail segment.

  • Publication number: 20150213178
    Abstract: Among other things, one or more systems and techniques for tier based layer modification, such as promotion or demotion, for a design layout are provided herein. A metal scheme describes one or more metal layers of the design layout, which are grouped into a set of tiers based upon resistivity similarity between the metal layers. Wire segments of the design layout are evaluated for promotion to tiers providing improved performance, for demotion to tiers providing decreased performance so that relatively faster routing resources are freed up for other wire segments, or for modification such as widening of wire segments. Via count penalties corresponding to timing delays of additional vias used to reassign wire segments are taken into account during promotion. Routing resource gains associated with reassigning wire segments are taken into account during demotion. In this way, wire segments of the design layout are promoted, demoted, or modified.

  • Publication number: 20150200159
    Abstract: In some embodiments, a semiconductor arrangement comprises a stacked interconnect structure comprising a first interconnect structure and a second interconnect structure. The stacked interconnect structure has a relatively larger aspect ratio than the first interconnect structure or the second interconnect structure, which reduces resistivity and improves performance. In some embodiments, a duplicate interconnect path is inserted into a design layout for a semiconductor arrangement. The duplicated interconnect path provides an additional path between a first net and a second net connected by an interconnect path. Connecting the first net and the second net by the interconnect path and the duplicated interconnect path reduces resistivity and improves performance. In some embodiments, a semiconductor arrangement comprises cell pin operatively coupled to a duplicate cell pin. The cell pin and the duplicate cell pin are operatively coupled to a logic structure to reduce resistivity and improve performance.
