Abstract: A method generates a design layout for an integrated circuit. A design is provided for an integrated circuit. Library cells are selected according to the design. The library cells are mapped into a chip area map. Unmapped cells are filled with filler cells. Critical cells of the library cells are selected. The selected critical cells are altered with respect to contact resistance and/or contact capacitance. The map including the altered cells is provided as the design layout.

Abstract: An integrated circuit. The integrated circuit comprises an area having a layout aligned in rows. Each row is definable by a pair of row boundaries. The integrated circuit also comprises a plurality of cells, comprising a first set of cells. Each cell in the first set of cells spans at least two rows and comprises a PMOS transistor having a source/drain region that spans across one of the row boundaries and an NMOS transistor having a source/drain region that spans across one of the row boundaries.

Abstract: determining piece-wise polynomials which together would represent large data sets having multi-dimensional input vectors and corresponding output element. In an embodiment, a function/procedure/routine is recursively called/invoked to determine piece-wise polynomial is a data set cannot be entirely modeled by one polynomial. Another aspect of the present invention reduces the number of combinations (of orders for sub-polynomials forming the polynomials) to be tried in determining polynomials, meeting various accuracy requirements. Such a reduction is obtained based on a recognition that when the order in one dimension alone is increased and the result does not lead to acceptable accuracy of the polynomial, the combinations with a lesser number for the order (of the dimension) can be ruled out.
