    摘要: An integrated circuit (IC) including at least one combinational logic path. The features in the combinational logic path are self compensating for out-of-focus effects. In particular, field effect transistor (FET) gates may be iso-focally spaced such that the gate (critical dimension) may move with changing focus, but the gate length remains the same. Alternately, logic circuits in a path may self-compensate for focus effects on individual circuits.

    摘要: A method and system for layout optimization relative to lithographic process windows which facilitates lithographic constraints to be non-localized in order to impart a capability of printing a given circuit with a process window beyond the process windows which are attainable with conventional simplified design rules. Pursuant to the method and system, lithographic capability and process windows are maximized to satisfy local circuit requirements and in order to achieve a maximally efficient layout. In this connection, there is employed a method utilizing a generalized lithographic process window as a measure when layout optimization is extended to a degree beyond that achieved by the simple fixed design rules which are applied to the design rules obtained is the advantage that a lithographic process window is determined purely through the calculation of image intensities and slopes, and as a result, the method can be quite rapid in application because it is possible to take advantage of known methods for rapid calculation of image intensity, and because there is obviated the need for geometrical shape processing during optimization.

    摘要: An integrated circuit (IC) including at least one combinational logic path. The combinational logic path includes two types of logic blocks cells that compensate each other for fabrication parameter effects on cell transistors. The two types may be dense cells with field effect transistor (FET) gates on contacted pitch and isolated cells with FET gates on wider than contacted pitch. Dense cell delay changes from the FET gates being printed out of focus are offset by isolated cell delay changes.

    摘要: In connection with the manufacture of chips having partitioned logic, a partitioned mask layout approach. This approach provides the chip exposure pattern as a set of partitions corresponding to macros or core functions and also handles glue logic and interconnect. A result of this approach is a simplified, cost-effective process that does not defer customization to other, potentially more time-consuming and inefficient tasks.

    摘要: This specification describes a decoder for use in a programmable logic array (PLA) of the type having opposite ends of input lines of the array connected to outputs of different decoders. Instead of using the outputs of two two-bit decoders to drive four input lines, as was previously done, four one-bit decoders are used to drive the four input lines. This arrangement permits the one-bit decoders with minor modifications to be used to perform four one-bit decodes of four input signals, two two-bit decodes on two sets of two input signals on either side of the array and one two-bit decode on two input signals that are on opposite sides of the array.

    摘要: This specification describes a decoder for a programmable logic array (PLA) having opposite ends of input lines of the array connected to outputs of different decoders. Previously two-bit decoders were arranged on opposite sides of the array to generate input variables from two sets of two different input signals each and feed those input variables to four input lines. Here, instead of using two-bit decoders, four one-bit decoders are positioned on each side. The outputs of these one-bit decoders are programmable to change the connections between them and the input lines of the array. The arrangement permits the decoders to perform one-bit, two-bit decoding on signals on the same side of the input lines, to do two-bit decoding on signals on opposite sides of the array and in combination with other sets of decoders to do three and four-bit decoding of input signals.
