Abstract:
An apparatus for extracting a parameter of a component, said apparatus comprising:discretizing means for discretizing said component into a plurality of regions;quadrature node generating means for dividing said regions into a plurality of quadrature nodes;pairing means for forming a plurality of pairs from said quadrature nodes;processor means for computing a Green's function for each of said pairs formed from said quadrature nodes;memory means for storing said Green's functions generated by said processor means for said pairs;allocating means for allocating each of said pairs to a far field and a near field based on a criterion;first computing means for computing a Gaussian quadrature for said pairs allocated to said far field;second computing means for computing a high order quadrature for said pairs nodes allocated to said near field;combining means for combining information derived from said Gaussian quadrature and said high order quadrature to simulate said component,wherein said criterion for allocating each of said pairs includes the order of said high order quadrature, an accuracy, and said Green's function for each of said pairs and wherein said means for computing said high order quadrature includes a plurality of basis functions, said basis functions, denoted .psi..sub.i.sup.k (r'), comprising 1,x,y,x.sup.2,xy,y.sup.2.
