Process of fitting function parameters that facilitates accurate pattern-based 3d capacitance extraction

A computing system comprising:

• a memory;
• and
• at least one processor, coupled to said memory, and operative to perform operations comprising:
• determine a wiring pattern for performing pattern-based 3D capacitance extraction;
• determine a target wire included in the wiring pattern;
• divide the target wire into segments based on effective spaces of the various crossing wires;
• determine a capacitance analysis that applies for each of the segments;
• determine a plurality of capacitance results corresponding to the capacitance analysis applied to each of the segments;
• and
• accumulate the plurality of capacitance results to extract a total capacitance corresponding to the target wire,
• wherein the segments are based on an effective spacing of crossing wires included in the wiring pattern, which are located above the target wire and extend across the target wire, and
• wherein the effective spaces of the various crossing wires are determined using a parameterized function (f(s)) that implements at least two adjustable parameters that are set to obtain the wiring pattern using a fitting process.
