摘要： Methods for modeling a random variable with spatially inhomogenous statistical correlation versus distance, standard deviation, and mean by spatial interpolation with statistical corrections. The method includes assigning statistically independent random variable to a set of seed points in a coordinate frame and defining a plurality of test points at respective spatial locations in the coordinate frame. A equation for a random variable is determined for each of the test points by spatial interpolation from one or more of the random variable assigned to the seed points. The method further includes adjusting the equation of the random variable at each of the test point with respective correction factor equations.

摘要： A method calculates a total source/drain resistance for a field effect transistor (FET) device. The method counts the number (N) of contacts in each source/drain region of the FET device, partitions each source/drain region into N contact regions and calculates a set of resistances of elements and connections to the FET device. The measured dimensions of widths, lengths, and distances of layout shapes forming the FET and the connections to the FET are determined and a set of weights based on relative widths of the contact regions are computed. The total source/drain resistance of the FET device is determined by summing products of the set of resistances and the set of weights for each of a plurality of contacts in series, the summing being performed for all of the plurality of contacts in one of a source region and a drain region of the FET. A netlist is formed based on the total source resistance and total drain resistance of the FET device.
