Abstract:
In a method of operating a computer to provide assistance in the design and modeling of integrated circuits, one of said integrated circuits including an electrical interconnect circuit that is described by measurable parameters that depend on geometric parameters determined by a vector x, said measurable parameters further depending, on the frequency, f, of an electrical signal passing through said interconnect circuit, said computer aided design requiring a value for one of said measurable parameters, the improvement comprising:storing information representing a plurality of coefficients that depend on f, C.sub.m (f);storing information specifying, the values of a plurality of multinomial functions, P.sub.m (x) for m=0 to M, wherein M>1; andcomputing an approximation, M(f,x), to one of said measurable parameters according to the relationship: ##EQU16##wherein each P.sub.m (x) is a multinomial for m>0.
