    摘要: A method for designing an integrated circuit involves a four step process. First, a behavioral circuit model (BCM) is read which contains assignment statements which identify the logical operation of an integrated circuit (IC). The BCM is translated to a data file which described a plurality of interconnected logic gate functions to duplicate the operation of the BCM. The gates in the data file are then assigned a specific Vdd and ground rail size, a specific drive strength for speed considerations, and a cell pitch or height to optimize physical layout, in any order. The result in a physical design file which may be used to form masks and integrated circuits having optimized speed and optimized circuit area in a short design cycle.

    摘要: A method and apparatus for designing and manufacturing integrated circuits (ICs) involves providing an initial library of IC cells (106) and a behavioral circuit model (100) in order to create a gate schematic netlist (102). The gate schematic netlist (102) is optimized by changing individual transistor sizes, power rail sizes, cell pitch, and the like in a step (103). Once the optimization has occurred, the initial library can no longer be used to place and route the IC. Therefore, a hybrid logic cell library is created from the gate schematic netlist (102) via a step (105). This hybrid library and the above optimizations provides a placed and routed IC via a step (126) in a short design cycle while optimizing performance of the IC.

    摘要: An integrated circuit, when designed, must adhere to timing constraints while attempting to minimize circuit area. In order to adhere to timing specifications while arriving at a near-optimal circuit surface area, an iterative process is used which selectively increases logic gates sizes by accessing logic gates from a memory stored logic gate library. A circuit representation is read along with timing constraints for circuit paths. Each circuit path in the circuit is processed to find it's actual circuit path delay. A most out-of-specification circuit path (in terms of speed) is chosen in the circuit and a sensitivity calculation is performed for each logic gate in the most out-of-specification circuit path. The logic gate in the circuit path with the maximized sensitivity (sensitivity=.DELTA.speed/.DELTA.area) is increased in size by accessing a larger gate in the library in order to improve speed at the expense of area. The above process continues iteratively until no out-of-specification circuit paths are found.

    摘要: An emulator including a beam splitter for splitting incoming light energy into a first component directed along a first optical path, and a second component directed along a second optical path distinct from the first optical path. The emulator includes a first receptacle positioned to pass light energy directed along only the first optical path. The first receptacle is capable of receiving an add lens for providing an add power. A beam combiner is positioned to combine light energy of the second component with light energy of the first component that has passed the first receptacle, i.e. to have the add power applied, and to direct the combined light energy along a common optical path. Additional receptacles are provided that are capable of receiving a sphere and/or a cylindrical lens in position to pass the combined light energy traveling along the common optical path.

    摘要: The invention provides contact lenses that substantially block either or both UV and blue light from entering the lens wearer's pupil by providing multiple concentric areas of certain materials that decrease or substantially eliminate the UV and blue light transmission. The lenses of the invention accomplish the light blocking without degrading the lens wearer's vision.
