SYSTEM AND METHOD FOR THREE-DIMENSIONAL VARIATIONAL CAPACITANCE CALCULATION

摘要

Capacitance extraction techniques are provided. In one aspect, a method for analyzing variational coupling capacitance between conductors in an integrated circuit design is provided. The method comprises the following steps. Coupling capacitance is computed between conductors of interest from the design using a set of floating random walk paths.One or more of the conductors are perturbed. Any of the floating random walk paths affected by the perturbation are modified. The coupling capacitance between the conductors of interest is recomputed to include the modified floating random walk paths.
