Abstract
A method for timing analysis includes using the processor to determine an impedance profile of a coupling between at least a first inter-level via (ILV) and a second ILV or a device, as a function of at least different frequency values. The impedance profile includes a plurality of impedance values corresponding to respective frequency values. An effective capacitance value corresponding to each respective impedance value is determined. At least one table is provided with respective impedance values and respective effective capacitance values for each respective frequency value. An RC extraction of a design layout of an ILV circuit is conducted using the populated table and based on determined effective capacitance values.
